Conference – Hoopoe – A blog by nhbs

South West Marine Ecosystems conference 2024

The 2024 South West Marine Ecosystems (SWME) conference was held at the Plymouth Marine Laboratory in April. Running since 2007, the conference brings together organisations and individuals involved in research on and management of the marine environment to report on annual system changes in the south-west. The conference covers the oceanography, plankton, seabed and seashore, fish, seabirds, seals and cetaceans of the south-west. Alongside key trends and interesting occurrences from the past year, SWME also encompasses management themes: marine planning, protected areas, fisheries, water quality and plastic pollution. This year’s theme focussed on the interconnectedness of the environment and its management, demonstrating this connectivity through interaction and discussion between guest speakers. In this blog we provide a roundup of SWME 2024.

Environment

The first session began with a rundown of oceanography and weather conditions across the UK, setting the scene for our marine environment. The UK experienced an increase in mean air temperature and increased sunshine duration over winter. There was also a decrease in mean rainfall across the UK and record-breaking heatwaves – some of us may remember the scorching temperatures of June last year, a worrying 2–3°C anomaly.

From March 2024, a new bylaw prohibits the use of bottom towed gear in defined areas of 13 marine protected areas (MPAs). Hartland Point to Tintagel Marine Conservation Zone (MCZ), Cape Bank MCZ, Lands End and Cape Bank MCZ, South of Celtic Deep MCZ, Wight-Barfleur Reef MCZ, East of Haig Fras MCZ and Greater Haig Fras MCZ are the MPAs that will benefit from this designation in the south-west. Devon Wildlife Trust vocalised a desire for a ‘whole-site approach’ for MPAs in the region – managing the site in its entirety, not just where protected species or features are present.

The Devon Maritime Forum stressed an urgency to address issues surrounding water quality in the south-west. They reported that no single stretch of river was found to be in ‘good’ overall health in 2023 – with quality impacted by agricultural run-off, sewage overflows, climate change and urban diffuse pollution. The UK Government has pledged to invest £1.6 billion to improve the water quality of rivers, lakes and coastal waters. Investments will be used to tackle storm overflow discharges, treatment works pollution and water resilience. South West Water will also be investing £70 million to upgrade infrastructure to reduce discharges in the region.

Analysis of plastic pollution showed that polyethylene was the most common material in plastic waste and marine litter fragments. To tackle the issue of plastic pollution on a global scale, the Global Plastics Treaty is under negotiation, and is expected to be legally binding by 2024. The treaty will address the full life cycle of plastic products and aim to end the pollution by these materials worldwide.

Key points:

Higher average winter temperatures and sunshine, with decreased rainfall were observed in 2023
A new bylaw will prohibit the use of bottom-towed gear in seven MPAs.
The UK Government has pledged to invest £1.6 billion to improve freshwater and coastal water quality
The Global Plastics Treaty will be legally binding by the end of 2024, intending to end plastic pollution

Organisms

Plankton researchers saw a higher abundance of salps (a barrel-shaped pelagic tunicate), consistent with a general increase in filter feeders over the past 30 years. There was also an influx of Barrel Jellyfish strandings across the south-west, with the species accounting for 27% (467) of the annual total of jellyfish sightings. A new method of plankton sampling has been developed, called Automated In-situ Plankton Imaging and Classification System (APICS). This new technology will help to determine the impacts of environmental changes on plankton, allowing for long-term, broad-spectrum measurements of the group.

New observations have improved our understanding of Basking Shark behaviour, revealing that this species may remain in UK waters throughout winter, instead of migrating south as previously believed. Blue Sharks were also caught more readily than previous years, exhibiting a higher catch per unit effort (CPUE), with over 1,000 caught off the coast of Looe, in Cornwall. The UK had its first sightings of Smalltooth Sand Tiger Shark, with a 10-foot individual washing up in Lyme Regis, Dorset. Typically seen in tropical and temperate waters, the discovery of this species in the UK is indicative of the effects of climate change on marine megafauna. Atlantic Bluefin Tuna have also been returning to the south-west with most sightings between July and February. There has been a marked increase in catch rate (over 5,000 were landed in 2023) which has prompted the introduction of fisheries plans (see below).

Rat eradication has been hugely successful for a number of seabirds. On Lundy, Manx Shearwaters and Puffins have responded positively and have seen population increases in 2023, and Storm Petrels have recolonised the island. Razorbills and Guillemots are also recovering well and are breeding successfully without predation from rats. The south-west has luckily missed the worst of avian influenza, although some small gulls and terns were affected in Dorset last summer. However, Kittiwakes are having local productivity issues which is prompting concern, and several species of gull are experiencing significant declines: Herring Gulls, Lesser Black-backed Gulls and Great Black-backed Gulls have all experienced losses over 40%. The English Seabird Conservation and Recovery Pathway (ESCaRP) report was published at the start of 2024, highlighting the sensitivity of seabird species to a range of pressures. Vulnerability assessments were conducted to inform the recovery pathway, and the report has made recommendations for conservation measures to address negative impacts.

There are concerns over the impacts of climate change on Humpback Whales. Increasingly, we are seeing individuals which are choosing not to migrate and are instead remaining in UK waters. Researchers believe that these animals are not undertaking seasonal movements due to a lack of food resources during winter – demonstrating that decreased productivity at the base of the food chain can cause issues further down the line for other marine organisms.

Key points:

New technology will provide a greater understanding of the impact environmental change may have on plankton
Atlantic Bluefin Tuna and shark sightings have increased in the south-west, including the Smalltooth Sand Tiger Shark, never previously recorded in the UK
Rat eradication programmes have been hugely successful in protecting seabirds
Kittiwakes and a number of gull species are experiencing declines
Climate change is thought to be impacting Humpback Whale migration

Industry

The Crown Estate have announced plans to develop more offshore wind farm projects, generating an additional 4GW of electricity to contribute to the 50GW by 2030 goal. This additional capacity could power up to four million homes, contributing to the UK target of net zero by 2050. Large, floating platforms have been proposed to enable deployment in deeper water – installation further offshore provides more reliable wind resources, generating more power for the same installation on-shore. There have been assessments to prepare for the deployment of extensive offshore wind in the south-west – with pre-consent surveys run by The Crown Estate. Celtic Sea Power, owned by Cornwall Council, is supporting offshore roll-out and has identified areas for data collection in the region. There are three project development areas where aerial, geophysical, acoustic and LiDAR surveys are taking place to improve data collection, accelerating the programme. The Poseidon Project was established by Natural England to provide a sensitivity map across the EEZ (exclusive economic zone –a surrounding area of 200 nautical miles offshore, where the nation has jurisdiction over resources) through digital aerial surveys. Collecting detailed information on seabirds, marine mammals and habitats, the project aims to improve models of abundance and distribution for key species which may be impacted by offshore development.

Sardine and Anchovy stocks are reported to have had a good year, continuing to support fisheries in the south-west, while Sprat fisheries have slowed due to insufficient stock size and 0-group fish (fish in their first year of life). We can see that new fisheries are emerging in the region (e.g. Atlantic Bluefin Tuna quota of 39 tonnes), while other, more traditional stocks are declining (e.g. Edible Crab). Five fisheries management plans have been developed for bass, King Scallops, crab and lobster, whelk and non-quota demersal species – these plans are put in place to deliver sustainable fisheries while minimising negative impacts on marine species. Dogger bank SAC, The Canyons MCZ and Inner Dowsing, Race Bank and North Ridge SAC were protected from damaging fishing activity in 2022 by prohibiting trawls, seines, dredges and bottom towed gear – this bylaw seeks to protect cold-water coral reefs, seabed, sandbanks and biogenic reef.

Key points:

Offshore wind development is being accelerated by better data collection and availability, supporting the UK in reaching renewable energy targets
Some traditional stocks are declining, while new fisheries are emerging
Five fisheries management plans were introduced
Four areas of conservation concern were protected to prohibit bottom towed gear

This year’s conference was an enlightening insight into the marine ecosystem in the south-west and highlighted some inspirational conservation work undertaken by several organisations, and individuals, dedicated to this environment. The SWME YouTube channel has a selection of webinars and further information on the conference can be found on the SWME website.

European Botanical and Horticultural Libraries Group (EBHL) Annual Conference

From Tuesday June 20th to Friday June 23rd, NHBS attended the business meeting of the European Botanical and Horticultural Libraries Group, or EBHL for short. This annual conference brings together librarians from academic libraries and herbaria for several days of talks and behind-the-scenes tours. For NHBS, this is always a valuable occasion to meet and speak to some of our key customers in person, both from Europe and the USA. This year, the meeting took place in London and was co-organised by four institutes: The Natural History Museum, London; The Royal Botanic Gardens, Kew; The Linnean Society of London, and The Royal Horticultural Society. So, what happens at such a meeting?

A Wardian Case on display at Chelsea Physic Garden

This year’s theme was “plant humanities”, resulting in an eclectic mixture of talks from, not just librarians, but also historians and arts and humanities scholars. For example, medieval historian Isabel Davis talked about digitisation of collections and the drawbacks and advantages that come with dealing with scanned documents rather than the originals. Mark Nesbitt and Kiri Ross Jones both related the experience of Kew in developing an interdisciplinary research programme with external partners in fields outside of botany. A recurrent theme in several of these talks was how botanical gardens are dealing with their origin and history as colonial institutes, and the legacy of their collections that have been built with objects taken from other countries. Given today’s discussions and debates around decolonisation, this is, understandably, a topic that requires serious attention, and humanities scholars and historians can often bring new perspectives and ideas to the table. Palace of Palms author Kate Teltscher, for example, spoke about a new project she is working on that will reexamine the history of Kew, which might just result in another book.

The Royal Botanic Garden, Kew now has a permanent treetop walk in its garden offering stunning views across London.

This conference also saw a break-out session, chaired by Dr Anna Svensson from Uppsala University, on a topic of particular interest to archivists: the presence of pressed plants, or traces thereof, inserted in old books. She is studying these as part of a three-year research project to identify why people did this, how it relates to the development of early bound herbaria (books known as horti sicci, the plural of hortus siccus), and what conservation challenges they pose for archivists and librarians.

The Linnean Society has a rare collection of documents and books that belonged to Karl Linnaeus, including early editions of his works that he annotated while developing his system of biological nomenclature.

Alongside this busy programme of talks, during the afternoons the organisers had arranged behind-the-scenes tours around parts of the collections of all four institutes that are normally not accessible to the public. As such, on Tuesday I was able to marvel at Sir Hans Sloane’s collection of bound herbarium books that are held at the NHM in London. Not only did he put together some of these himself, later in life he bought or inherited collections of other people, resulting in over 200 large volumes with pressed plants from around the world. In the evening, I stood right next to a Wardian case during a tour of the Chelsea Physic Garden. Wednesday I admired some remarkable archival material at Kew (and enjoyed their treetop walk), while on Thursday I marvelled at the large collection of original manuscripts and books from Carl Linnaeus that are held in the basement room of the Linnean Society. This included a copy of an early edition of the Systema Naturae that has his handwritten annotations all over the margins. Friday the whole group took a coach to RHS Wisley, just outside of London, where we toured both the original research buildings and the brand-new library and herbarium of this remarkable horticultural institute.

The new library at RHS Wisley has been awarded several prizes for its architecture and offers views into the garden throughout the building.

We would like to thank the organisers of this year’s conference, in particular Isabelle Charmantier and Will Beharrell who headed it all up. NHBS is looking forward to next year’s meeting and welcomes opportunities to develop closer ties with some of the professional and amateur organisations that we count amongst our customers, whether through attendance or sponsorship. Do not hesitate to reach out to us.

South West Marine Ecosystems Webinar Programme 2022: The State of the South West’s Seas

The South West Marine Ecosystem conference series has been running for more than a decade, bringing together those involved in marine conservation, scientists and managers to share information to improve understanding, future monitoring and management.

This series of webinars on the state of the south-west’s seas presented a number of topics, including cetaceans, climate change, seals, south-west fisheries in 2021, marine and coastal birds, fish and turtles, oceanography and plankton, seashore and seabed, water quality and marine protected areas. These webinars give a well-rounded update on the south-west marine ecosystem, its processes, challenges and successes. We were very pleased to be able to support and attend this series of webinars. Below is a summary of some of the engaging and thought-provoking talks from what was an insightful and educational programme.

Seals:

The Cornwall Seal Group Research Trust (CSGRT), who work to survey, record and process data for the identification and monitoring of seals within the south-west, discussed the current state of the grey and common (harbour) seal populations in the region. The webinar highlighted the threats seals face in south-west waters, including entangling and disturbances. There was a large number of disturbances seen in 2021, with almost 1,500 seals affected. These disturbances can be caused by a number of human activities, including noisy walkers, dogs, beachgoers, kayaks, SUPs, small watercraft, commercial fishing boats and local trip boats. The impact of instances such as entanglement and disturbances are cumulative, having severe consequences on the survivability of seals.

Marine impact deniers, apathy, misconceptions and the general prioritisation of humans over wildlife seriously impact the conservation efforts for seals in the UK, but CSGRT are working to counteract this within the south west. Through conservation activities, censuses and public awareness campaigns, the CSGRT has managed to promote best practices amongst a number of companies to reduce their chances of causing disturbances. They have also been working with Natural England and National Trust to install trail cameras, checked and monitored by a local volunteer, to record the response of seals to the presence of people.

Marine and Coastal Birds:

The south-west marine ecosystem is home to a vast number of seabirds. Regionally, there is also a mixed picture of the health of seabird populations, with population recovery and decline in different species across Lundy, the Isles of Scilly, Cornwall, Devon and Dorset.

In 2021, RSPB staff and volunteers reassessed the abundance and distribution of cliff-nesting seabird populations on Lundy, forty years after the initial census in 1981. They found over 27,000 breeding seabirds on the island, mainly auks and Manx shearwaters. In 2000, the seabird population was approximately 6,000, but since the removal of rats in 2004 populations have been able to make an amazing recovery. Historically, however, the area supported around 80,000 birds, suggesting that further conservation efforts and surveys are needed.

In the Isles of Scilly, rat removal on certain islands has also contributed to an increase in some seabird numbers and breeding success, such as for the Manx shearwater. The number of breeding pairs of kittiwakes, however, has been declining over the last few decades, and last year, for the first time in living memory, there were no kittiwakes nesting on the Isles of Scilly.

In Cornwall, Devon and Dorset, certain seabirds are also declining, including a steep decline in the main wintering population of black-necked grebes in Carrick Roads, Cornwall. There is no obvious reason for this decline, as there are fewer disturbances and better management of the area. In Exmouth, Devon, occupied kittiwake nests have been increasing since 2000, but their breeding success has been reducing since 2018, from an average of 1.05 to 0.43 overall across all 3 plots monitored. In Dorset, several species are struggling, even with close management and conservation. On Chesil Beach, only 3 little tern chicks successfully fledged from 48 nests, 155 eggs and 102 chicks.

In the near future, there are several key areas that need addressing to help seabird conservation efforts in the south west. More standardised recording is needed in key estuarine sites, to ensure that there is proper data on populations such as the black-necked grebes. Additionally, there needs to be closer monitoring and increased take-up of nest recording for widespread seabirds, as well as management of possible tourism disturbance.

Seashore and Seabed:

Using information harvested from observations on social media and other sources, Keith Hiscock of the Marine Biological Association presented the state of the seashore and seabed of south-west seas in 2021. By comparing current sightings with previous records, such as the recording of Poecilochaetus serpens in 2021, where it was previously noted in 1902, the persistence of species and biodiversity within these areas can be analysed. They were able to see the gains and losses of species on the seashore and seabed, for example lower numbers of crawfish (Palinurus elephas) in areas where significant numbers had been seen in the last few years, and increases in abundance and extent of other species, including Zostera noltii and Z. marina.

They were also able to note the presence of new species within areas of the south west, including the Mediterranean feather duster worm (Sabella spallanzanii), and the increasing abundance and extent of non-native species, such as the Pacific oyster (Magallana gigas). The number of non-native species within south west waters has continued to grow, with the range and abundance of some species already present also increasing. The very slight increase in the presence of warm water species suggests that ocean warming is having an effect, but it is not having a marked impact on biota composition. Overall, this webinar called for a better process for the systematic recording of events and change in south-west seas.

Our thoughts

This year’s webinar programme was an enlightening insight into the ecosystem of the south west, as well as the ongoing conservation efforts undertaken by multiple different groups and volunteers across the region. For those who were unable to attend the live lectures this year, recordings of each are available on the South West Marine Ecosystems youtube channel. Further information about conferences can be found on their website, along with an archive of their previous conferences.

2022 Herpetofauna Workers Meeting: Part 1

Invasive non-native species cost the UK approximately £122 million per year and are a huge driver of biodiversity decline worldwide. There are a surprising number of non-native reptile and amphibian species in the UK, from non-breeding released pet terrapins to established populations of midwife toads, although the impact of some of these species on our native wildlife is not yet fully understood.

The first part of the 2022 Herpetofauna Workers Meeting included a number of talks that discussed the latest research on introduced reptile and amphibian species in the UK, including the Aesculapian Snake in Wales and the Alpine Newt in Northern Ireland. We were pleased to be able to attend and take part in this event again this year, and below is summary of some of the fascinating talks from what was an interesting and informative afternoon.

The Aesculapian Snake

The Aesculapian Snake Zamenis longissimus is a non-venomous species found across southern and central Europe, with relic populations in northern Europe. Although not native to the UK, there are two known introduced populations, one on the grounds of the Welsh Mountain Zoo in Colwyn Bay, Wales, and another along Regents Canal in London. There is also a possible third population in Bridgend in South Wales, but this is unconfirmed as of yet. Tom Major from the University of Bangor is using radio telemetry to study the population at Colwyn Bay to understand how this species is surviving, and he has gained some incredible insights into the ecology of the Aesculapian Snake over the past year.

While tracking nine adult individuals he found that on average the snakes travel the distance of approximately three and a half rugby pitches, and tend to visit one particular place where they stay for roughly four days before setting off again. This seemed to be anywhere that was warm and dry, from a chapel roof to a compost heap. By the end of the tracking period four individuals were still alive. Buzzards, stoats and cars were the reasons behind a few of the deaths, but one interesting cause was cannibalism – one tracked snake was recorded being eaten by another tracked individual, the first known occurrence of this behaviour in this species.

Turtle Tally

Reptiles and amphibians are becoming increasingly popular pets, but a lack of knowledge of their complicated care requirements or an unexpected change in an owner’s circumstances, amongst other reasons, can lead to the intentional release of these exotic animals into the wild. In order to gain an understanding of the distribution and impact of released pet terrapins in the UK in particular, Turtle Tally UK is a nationwide citizen science project that calls for the general public to submit their own terrapin sightings and photos. During her talk, Turtle Tally project lead Suzie Simpson shared some of the findings since the project began in 2019. Each year since has seen an increase in the number of sightings submitted, and hotspots have become apparent in London, Cardiff, Swansea and Liverpool. Yellow-bellied and Red-eared Slider were amongst the most frequently recorded species, and generally only one individual was recorded per sighting.

When they are out of water, terrapins are usually spotted on logs, rocks and even litter – any raised platform in a water body that they can use for basking. This also includes the nests of waterbirds, but so far there has been no evidence that these terrapins show signs of aggression to waterbirds, or that they predate on chicks. Some species, such as snappers and soft shells, would be more of a concern, however, and the Turtle Tally UK project aims to continue to collect data to further our understanding about the impacts of released pet terrapins on native wildlife. Egg laying has been observed on occasion, but due to the UK’s cooler climate, reproduction is very rarely successful. However climate change could result in more suitable conditions for breeding in the future.

The Alpine Newt in Northern Ireland

The Smooth Newt is Ireland’s only native species of newt and, with its distinctive orange belly and spotted pattern, it is easily recognisable. In September 2020, a strange looking newt was found in Northern Ireland during a bat survey. With a similarly orange belly, but without the spotted markings on its underside and darker in colour, this particular individual did not match the description of a Smooth Newt. It was soon confirmed that this was an Alpine Newt, a species found in Europe but not native to the UK. The discovery of this species is a particular concern as the Alpine Newt is a known vector of chytrid fungus. Rob Gondola, Ryan Boyle and Éinne Ó Cathasaigh provided an update of the consequent Alpine Newt surveys that took place during the following summer in 2021. Thankfully, all the swabs that were taken to test for diseases have come back negative, and they were able to determine the presence of two established populations. Further surveys and testing are hoped to continue in 2022.

Our thoughts

There were a number of other talks throughout the conference, from the ongoing study of midwife toads in the UK (another non-native species that was introduced over 100 years ago) to the impact of climate change on UK herpetofauna. This was an enlightening and fascinating afternoon and we look forward to Part 2 of the 2022 Herpetofauna Workers Meeting later on in the year. The date and location of the event will be confirmed at a future date, but any details will be made available on the ARC or ARG UK website. A recording of Part 1 will also be made available – keep an eye on the ARC website for further details.

Bat Conservation Trust – National Bat Conference

The Bat Conservation Trust’s annual National Bat Conference, held online via Zoom from 29th–31st October, covered many aspects of bat conservation through a wide variety of activities and talks, including monitoring, surveying and development. We are extremely pleased to have sponsored this event and we were lucky enough to have been able to attend many of these sessions, including talks by Professor Tigga Kingston from Texas Tech University on the human dimensions of bat conservation, and Thomas Foxley, University of the West of England, who spoke about the role of landscape features in spatial activity patterns of greater horseshoe bats. We also attended a few of the amazing workshops that took place, such as Shirley Thompson’s gardening for bats.

Bat Conservation Trust update

Bat Conservation Trust also shared an update on their current and future work. Bats make up more than a quarter of all mammal species in the UK, but sadly, these species face many threats. Habitat loss and fragmentation, decreasing food resources, chemical use, disturbance to roosts and threats from cats have all led to a dramatic decline in bat populations over the last century. Diseases, wind farms, flypaper, artificial lighting and the presence and construction of roads also negatively impact.

Currently, Bat Conservation Trust supports a number of local bat groups, working with volunteers, scientists, industry and government on a range of projects. They focus on discovering more about bats, taking action to protect them, inspiring people to care about bats and strengthening their work by improving relevant skills and knowledge. Their programmes include a National Bat Monitoring Programme, education and engagement, the National Bat Helpline, Landscapes for Bats, and science and research.

During this update, Bat Conservation Trust spoke of the many ways they will be increasing their efforts to help bat populations, for example by increasing the spread of their monitoring programs and organising a petition regarding key amendments to the Environment Bill, including legally binding targets for wildlife recovery. Through new acoustic and monitoring approaches, they also aim to improve their evidence base and Bat Conservation Trust are also working towards improving their engagement with policymakers, the public and the media. Their Bat in Churches project has also been expanded to include training on bat care basics, surveying a church, the best architectural practices for bats and cleaning workshops.

One key scheme they are developing is the Bat Roost Tree Tag Scheme where recognisable tags are placed on trees that contain bat roosts. The aim of this is to make sure all trees that have been surveyed and found to contain bat roosts are easily identifiable. When woodland managers and workers see a tag on a tree, they will know to seek advice before proceeding with work. This will also give a significantly increased level of protection for ancient trees, which are vitally important for a large number of species.

Future events and how to get involved

The National Bat Conference was a very interesting and educational event, and it was wonderful to see such a wide range of knowledge and skillsets being shared through the many talks, activities and workshops throughout the weekend. If you missed out this time or would like to attend further events, the Bat Conservation Trust has a number of future events planned, including Spring into Action, Midlands Bat Conference and the East of England Bat Conference. More information about these and other events can be found on the Bat Conservation Trust website.

There are a number of ways you can help to support Bat Conservation Trust, such as by becoming a member or donating. You can also contact your local bat group, fundraise for bats or volunteer for their various projects. However you choose to get involved, you can make a real difference to the future of bats in the UK.

6th International Berlin Bat Meeting 2021

The 6th International Berlin Bat Meeting was held online from 22nd–24th March 2021 and consisted of a series of varied and fascinating live lectures based around a timely theme: ‘The Human Perspective on Bats’. Over the three days, speakers from around the world spoke on topics such as bat coronaviruses, bat health, human interventions, bats in anthropogenic habitats, ecosystem services, conservation marketing and citizen science.

The first day of the conference began with a keynote talk from Prof. Felix Drexler (Institute of Virology, Charité Berlin) who spoke about emerging viruses with a focus on bats and SARS-CoV-2. He began by relating the fact that most (around 60%) of human pathogens have a zoonotic origin and that several notable animal-borne diseases have originated in bat hosts (eg SARS 2003, Ebola), although it is currently still debated whether bats are particularly prone to becoming reservoirs of zoonotic pathogens or whether they are just very diverse and numerous in comparison to most other mammals.

It is a constant challenge to predict where future diseases or pandemics may arise, although important factors appear to be Exposure (whether humans have close contact with the species), Ecology (aspects of the animals’ behaviour or ecology that are favourable for the maintenance and transmission of pathogens) and Evolution (as pathogens are more likely to cross species boundaries if species are genetically and antigenically related).

Moving forwards, Prof. Drexler suggested that better surveillance is required to respond to cases of zoonotic spillover, as an early response is vital in preventing future pandemics. This is particularly important in peripheral healthcare settings such as where small numbers of cases initially crop up in developing countries.

Later on in the day, Dr. Jon Epstein (EcoHealth Alliance, USA) continued this theme with a talk that looked at the interconnectedness of animal and human health. He stated that, although the exchange of microbes between animals and species is normal, many aspects of modern life, coupled with our dense populations, have made it more likely that pathogens will make the jump from animal to human. Emerging disease hotspots often show the same trends in terms of high species diversity, large numbers of intensively farmed livestock, high human population densities and land use changes which increase contact with local wildlife. Intensive agriculture, wildlife provisioning and legal or illegal wildlife trade, which often occurs in unsanitary ‘wet markets’, are thought to be particularly problematic.

As stated by Prof. Drexler in his earlier talk, Dr. Epstein concluded that surveillance is critical, alongside appropriate community interventions in cases where spillover has been found. These may include, but are not limited to, reducing the commercial trade of wildlife, building barriers so that wild animals cannot come into contact with farmed livestock and their food, and protecting food sources (such as the date palm sap that is widely collected in Bangladesh and which is often contaminated with saliva and faeces from local flying foxes who have exploited this practice as a useful food source).

Towards the end of the day we were treated to an interactive session from Dr. Tigga Kingston (Texas Tech University, USA) who used the online whiteboard, Miro, to allow the audience to discuss and document what they felt were the biggest challenges for bat conservation. Personal observations were added in the form of virtual ‘sticky notes’ to each category and then the audience was asked to vote on which areas they felt confident in tackling, and which they felt less able to deal with. Persecution of bats, habitat loss, and restrictions on fieldwork/research due to Covid-19 were found to be areas that people generally felt were the most problematic and challenging to address. The talk ended with a brainstorming session to pose various solutions to these issues.

The second day featured a session on ecosystem services. This began with a keynote speech from Dr. Rudolf de Groot who spoke about the economic importance of bats. Much of his talk focused on the limitations of our current economic models (eg GDP) when it comes to conservation and the environment, as conservation is generally only ever considered as a cost, while ecosystem values and services are rarely factored into the equation.

In a paper published in Nature (1997), the global value of ecosystem services and natural capital was calculated to be US $33 trillion. To put this into perspective, global GDP at the time was US $27 dollars. A later paper, published in Science (2002) estimated that the cost of ecosystem loss was 2-5% GDP per year, and this was expected to increase to 7% by 2050. (Interestingly, and worryingly, the amount currently spent annually on protected areas is US $24 billion, just 40% of the amount that is spent each year on ice cream).

Speaking more specifically about bats, Dr. de Groot listed several of the services that are dependent on bats, including pest control, pollination of more than 300 food plants and 80 medicinal plants, as well as the development of several important vaccines following research into bat viruses.

His concluding remarks reminded us of the importance of raising awareness and spreading the message about the value of the natural world and the services it provides.

On the third and final day of the conference we heard a fascinating talk from Dr. Diogo Verissimo (University of Oxford, UK / Institute for Conservation Research, San Diego Zoo Global, USA) titled ‘Can Conservation Marketing Save Bats’. Many of the sessions from the final day had focused on the importance of social scientists and biologists working together to implement change and promote conservation practices. Dr. Verissimo’s talk took this a step further by discussing how effective marketing can contribute to conservation science.

The problem with bats – he initially stated – is that people don’t like them. In multiple surveys conducted around the world, bats rank low on the list in terms of popularity, and the current Covid-19 situation has done little to improve this state of affairs. He then went on to discuss how Batman is, conversely, one of the biggest media franchises of all time, and this indicates that the way in which a subject or species is marketed and packaged can have a huge impact on its public appeal.

Dr. Verissimo explained that ‘social marketing’ involves the use of marketing principles to influence the behaviour of individuals and communities for the general good. When it comes to conservation this means that we need to show individuals how conservation and ecosystem services have a value to them, whether that is a tangible benefit (such as pollination being vital for the food they enjoy), or intangible (such as pride in a local rare species or habitat).

He went on to suggest that emotions are much better at driving change and decisions than facts, and environmentalists must always remember that everyone in the world is not going to think in the same way as them, as people have different life experiences and therefore different priorities. It is incredibly important to understand the target audience of any marketing campaign and to appreciate that only a small percentage of this audience are likely to be influenced – however, these are the people that need to be focused on. Finding out who they are is a huge part of the process.

In his final remarks, Dr. Verissimo stressed the importance of including social science research when considering conservation and conservation marketing campaigns. Although working in such an inter-disciplinary manner can be a challenge in itself, he believes it is critical for the future of global conservation.

The talks and poster presentations that we saw over the three days of the meeting were lively and varied and it was great to hear from people from a variety of disciplines and backgrounds. I’m certain that everyone who attended would join me in congratulating the organisers of the meeting for an exceptionally well planned and executed meeting that brought together people from around the world to share their expertise and opinions on ‘The Human Perspective on Bats’.

6th International Berlin Bat Conference – Interview with Christian Voigt

The 6th International Berlin Bat Meeting is due to be held online from 22nd–24th March 2021 and will consist of a series of live lectures delivered via video link. To make it possible for people to attend from around the world, the lectures will also be available to watch on demand. At NHBS, we’ve always loved being involved with the Berlin Bat Meeting and hope that soon we can attend again in person!

In the build up to this exciting event, organiser Dr. Christian Voigt kindly took the time to answer some questions about this year’s meeting. Dr Voigt is Head of the Department of Evolutionary Ecology at Leibniz Institute for Zoo and Wildlife Research, Lecturer at the Freie Universität Berlin and Member of the Berlin-Brandenburg Centre for Stable Isotope Ecology.

The theme of this year’s International Berlin Bat Meeting is ‘The Human Perspective on Bats’. Can you tell us why you decided to choose this particular theme?

We decided on this topic because we became aware of the necessity to address bat conservation from a more holistic approach. Conservationists often have the saying ‘wildlife management is the management of humans’ and this is very much true. We need to better understand the emotions and attitudes of humans towards wildlife in general and bats in particular, in order to protect wildlife and bats respectively. Ultimately, this will make conservation more efficient. The Covid-19 pandemic told us that we were right because many aspects of bat conservation have turned more difficult when some people changed their attitude towards bats. It is important to remember that bat conservation does not only mean dealing with the protection of bat populations but also with their ecosystem function. In many cases, bats are very helpful for humans, e.g. by consuming large numbers of pest insects or because they pollinate flowers or disperse seeds. Becoming aware of these ecosystem services might change people’s minds about why they should care for bats. Lastly, zoonotic diseases such as Covid-19 emerge because the way we treat wildlife is wrong. Poaching, wet markets, our whole interaction with wildlife has to be reconsidered and we will be talking about this during the International Berlin Bat Meeting. The topic of the upcoming IBBM `’The human perspective on bats’ is more relevant and timely than ever.

What do you think are the key conservation challenges currently faced by bats?

The major challenge is now to re-establish a good reputation for bats. Bats are key players in ecosystems, they are important indicator species, and many species are rare or even threatened. We need to care for them.

How do you hope that this meeting will contribute to the work required to address these challenges?

Our hope is that we come up with ideas about how to approach bat conservation and human-bat interactions from a different angle. This conference will bring together people from various geographic backgrounds and from a variety of disciplines. It is this exchange of ideas and perspective that make the IBBM quite unique among bat conferences.

Meetings such as these provide an unrivalled chance for attendees to share ideas and network. Do you know of any key projects or collaborations that have arisen from previous International Berlin Bat Meetings?

The networking that happens during these meetings is huge. The very first IBBM on bat migration brought this topic to the attention of many people and lots of papers have been published since then. Specifically, our meeting on bat diseases, right when white-nose syndrome hit North American bats, stimulated a lot of excellent research on both continents. I remember that we sat together during the IBBM and discussed what should be done and what to expect.

Organising an online meeting must be very different in comparison to organising an ‘in person’ event. How have you found the process? And have you noticed that there are benefits to this format, as well as challenges?

Organizing an online meeting is overall not difficult, it was the postponing of the conference, not knowing when to reschedule it and not knowing how people would respond to an online instead of a presence conference that caused us sleepless nights. Now that we have already organized a few online events, the task seems doable. Overall, the benefits are that people from many more places on our globe can participate in this event without having to pay the travel costs. The challenge for these kinds of conferences is to maintain a format in which people feel encouraged to discuss and to interact. This can be better achieved when you meet in person, e.g. during coffee breaks. It is my hope that we have a very lively discussion and a very stimulating event.

CIEEM Autumn Conference 2020: Time to Change

CIEEM’s “Time to Change: Putting the Environment at the Heart of Social and Economic Wellbeing” conference was accessed remotely, like so many of our gatherings this year. The virtual platform was used with great ease, allowing many people to access the talks which seamlessly focused on the various key speakers. The day also included live Q&As and breakout rooms, with all sessions ending in lively panel discussions. The conference took place over three days and focused on six different sub-topics. The general theme was ‘The Future’; how best to arm ourselves and the importance of collaboration, including people from all sectors and the general public.

At NHBS, we were particularly interested in the ‘New Tools and Technology Advancing Professional Practice’ session that was held on the final afternoon. This session covered Artificial Intelligence (AI), remote sensing and soundscape ecology, and explored the best methods of using the information that these technologies provide us with.

Tom August (UK Centre of Ecology and Hydrology) took us through how AI can learn when being used for species identification. It can also be a great tool for involving the public in research and an aid to improving our own identification skills. He discussed how we can help encourage technology learning by making positively identified photographs attached to species ecology widely available. He also assured us that AI is continually learning and improving: for example in 2014 AI could identify species to the same level as an average skilled person, whereas by 2017 it could function to just below the level of a species expert.

Jonny Miller and Joshua Aves (WSP) then took us through a working example of using drones and camera footage alongside GIS to improve survey and analysis efficiency (in this example up 70%). They explained that this can be great for creating baseline information and can help with safety when surveying more dangerous areas such as roadsides. They anticipate that the use of this technology will increase due to new needs to demonstrate biodiversity net gain.

Oliver Metcalf (Manchester Metropolitan University) demonstrated the use of audio recording devices to survey for various species and the benefits thereof. These benefits included removal of the surveyor effect on the target species’ behaviour as well as being able to analyse the same recording multiple times, in different ways and by different people – this helps to reduce error and increase the number of target species. When used in areas with reduced sight it can also be more productive than traditional visual surveys. His talk covered the drawbacks of the method, for example, there is no rule book around this technology, and if there is a loss of data then it is a big loss. At the moment, the technology is biased towards birds, and although large amounts of data are produced (which in itself has its benefits and challenges) there is not yet a wide database for all species. However, automated functions such as species identification and identifying false positives are continually improving. Oliver went on to explain that the use of acoustic indices does not require a high level of skill and has a huge variety of applications such as habitat type prediction (which maps well onto wilderness perception), variation in sound bar correlating to species richness, and detection of temporal trends.

As the use of all of these technologies result in large databases, Gregory Slack and Matthew Whittle (Jacobs UK Ltd) took us through a working example of how much data to collect at a site survey for bats and how to analyse it. They explained that there is a need to collect data with deeper analysis reporting more than means and medians (and believe this will be reflected in new guidelines) but that with use of acoustic recorders and statistical software such as R, minimal added survey effort does not add much when it comes to analysis, as this can be automated. Analysis like this can also be used throughout the study rather than only at the end.

The overarching takeaway from this session was that we should embrace the use of new technologies and that we all have a part to play in helping to develop them. There were discussions as to whether these new technologies would replace us (ecologists) but all speakers were reassuring that they would only make our lives easier. There was emphasis that their use should be carried out by (or at least alongside) ecologically trained professionals to provide meaningful data.

All of the talks from this inspiring session left me excited for the beneficial impacts of new technology.

CIEEM Online Conference Review

CIEEM’s summer conference this year discussed the urgent need to address the interlinked climate emergency and biodiversity crisis for the sake of the planet, the species and habitats it supports and for future generations. Due to lockdown and social distancing restrictions, the conference took place online, with speakers and participants attending from their homes via Zoom.

Wildlife Equipment Administrator Claire Graham attended the conference and has summarised her experience of the event and the talks below.

Logging into Zoom to take part in my first online conference, I couldn’t help but wonder if this is going to be the future of large events for a while… But, given the topic of the CIEEM conference ‘Climate and Biodiversity Crises: Professional Approaches and Practical Actions’, maybe there are positives to this! Certainly, creating a way to hold important conferences, without the need for everyone to have to travel (often long distances by plane or car) has its upsides.

So, with everyone speaking and listening from home, the day began with an introduction from Max Wade, the president of CIEEM. Following a quick mention of the unusual circumstances being dealt with by everyone this year and a reference to the growing importance of issues such as climate change and biodiversity loss, it was time for the first talk.

Diana Pound from Dialogue Matters opened with the keynote presentation: ‘Seize this Moment and Get Fresh Momentum’. She took us straight into a positive and inspiring talk, encouraging people to shift from an attitude of fear and doubt to one of optimism and hope. Diana asked us to highlight strengths instead of problems in conversations and dialogue, as a more effective way of motivating people to change, rather than focusing on everything that is being done wrong. Diana stated that the world is starting to wake up and a recent survey showed that 97% of those surveyed thought climate change was serious and 70% thought it was very serious. It also showed that 77% of people believe we should make as many lifestyle changes to stop climate change as we are doing to stop Covid-19. Overall, we were reminded to remain hopeful and be inspired to action; a quick poll demonstrated the power of this.

This led us into the next talk by John Box (from the CIEEM Action 2030 group) which discussed the actions that CIEEM are taking to deal with the interlinked climate emergency and biodiversity crisis. He provided lots of advice about offsetting carbon emissions and explained that CIEEM aim to achieve net zero carbon emissions in all its activities by 2030. John also emphasised the importance of environmental organisations sharing knowledge and building relationships.

Penny Anderson (a member of the Action 2030 group and Ecological Restoration and Habitat Creation SIG) followed with a talk about ‘Habitats and Carbon, Storage and Sequestration’. She explained that, to meet the latest 2050 net zero target, the Committee on Climate Change have recommended tree planting, peatland restoration and green infrastructure. Penny explained that around half of emissions from human activity are absorbed by land and oceans and the rest in the atmosphere. Surprisingly, there is globally 3-5 times more carbon in soils than in vegetation and 2-3 times more than in the atmosphere. All semi-natural habitats hold more carbon than arable or improved grassland and these types of habitats are also better for biodiversity. Therefore, we need to concentrate on diversity within habitats and not just think about trees; there is a simultaneous need to protect remaining habitats and minimise losses in soil while also undertaking habitat creation or restoration.

The next talk was by Ben McCarthy, the Head of Nature Conservation and Restoration Ecology with the National Trust. He explained the role the National Trust are going to play in the climate change and biodiversity crises, as well as the challenges they face as the largest land-owning NGO in Europe. Ben explained the organisations plan to repurpose farmland and create 20,000ha of new woodland and 25,000ha of new priority habitat, including restoring peatlands – a big challenge, but one they are determined to achieve! The National Trust recognise the significance of their land which is home to 44% of UK species including 737 that are threatened with extinction. Half of their properties have priority habitats that are highly sensitive.

Continuing on the subject of peatland restoration, the next talk was by Clifton Bain from the IUCN Peatland Project Programme. His talk on ‘The Peatland Code: Business Funding and Environmental Assessment’ discussed the importance of peatlands and their many benefits and gave an overview of the Peatland Code. The Peatland Code is a voluntary certification standard that helps to gain funding for peatland restoration projects by giving assurance to buyers; they fund the projects in exchange for climate benefits and mitigation. He compared the ecosystem services in healthy vs damaged peatland and discussed how damaged peatlands emit carbon rather than acting as a carbon sink. He also mentioned the loss of unique biodiversity that comes with damaged peatlands.

After lunch we jumped back into the next talk with Richard White from NatureBureau with his fascinating talk ‘Blue Carbon – The Sea, the Coast, and the Climate Crises’. Richard discussed ocean warming and acidification, sea level rise, shifting species distribution and methods of mitigation. He reviewed the role that ocean and coastal ecosystems have in the carbon cycle and the link between protecting and restoring marine biodiversity and mitigating our carbon emissions. Seagrass beds and saltmarshes act as globally significant carbon stores but only 21% of these habitats are currently protected by our Marine Protected Areas (MPAs). There is a need to work to protect these habitats and support restoration projects.

Richard Lindsay from East London University continued with more information about the importance of peatlands with his talk ‘Peatland Restoration and Carbon: Sphagnum, Carbon and Timescales’. He advised that, despite many peatlands and blanket bogs being damaged and emitting carbon, restoration projects can sometimes be challenged as successful carbon mitigation due to them being thought of as slow-growing systems. However, Richard discussed the use of adding Sphagnum to peat restorations due to it being a significant carbon sink and advised that it can be grown rapidly in optimum conditions.

The next talk was David Holland from Salix on ‘Soft Engineering Approaches to River, Wetland & Swale Projects’. He talked about the high carbon cost and negative ecological impacts of traditional hard engineering techniques and discussed low carbon solutions that can be used instead. Using natural materials and processes, rather than materials such as concrete, rock or metal, generates less waste, needs less future maintenance and improves the water quality and habitat, as well as providing vegetation that will continue to absorb carbon and benefit the environment.

The closing talk of the day was by Lee Dudley, Head of Environmental Carbon with the Woodland Trust and focused on ‘Carbon and Woodland Creation’. He explained that the Woodland Trust aim to conserve, restore and re-establish trees; their vision is a UK that is rich in native woods and trees for wildlife and people. The fact that woodland creation is now being recognised as a cost-effective method of climate change mitigation enables the potential for more woodland creation projects. Lee also discussed the importance of matching the right species to the right sites for the best outcomes and reminded us that it is not just about trees, but about the whole environment.

The day was wrapped up with a quick conclusion from David Parker from CIEEM. He thanked the speakers for all their extremely important and interesting talks and with that the event was over. My first experience of an online conference was positive all round; the talks were fantastic, and everyone enjoyed them from the comfort of their own homes with few technical difficulties. Hopefully the next conference can be attended in person but, if not, this experience has demonstrated there are definitely ways to keep talking and learning about these important issues.

Herpetofauna Workers’ Meeting 2020

Wind farms, conflicts in conservation, and the use of photo identification as a population monitoring technique were amongst the many themes covered at the 2020 Herpetofauna Workers’ Meeting. Running for over 30 years, this popular event attracts ecological consultants, academics, students, and conservation organisations from far and wide. As the weather worsened with the arrival of Storm Dennis, we settled in for a jam-packed two days filled with presentations, workshops, and poster displays.

So how is a talk on wind farms relevant at a herpetology conference? Wind farms cover a large expanse of land and, as Jeanette Hall from the Highland Biological Recording Group explained, could provide a conservation opportunity for Adders Vipera berus. Birds of prey are typically the main predator of Adders, but these predators are present in low numbers on wind farms. If managed correctly, wind farms could offer a suitable refuge for Adders. To test this Jeanette and her team used clay snake models to measure avian attack rates both within the wind farm and on a control site roughly a kilometre away. The models were made to roughly the same size as a yearling Adder, and the attacks were recorded by the presence of talon marks on the clay models.

Despite observing raptors in both sites, they found that attack rates were significantly lower on the wind farm. Interestingly, attack rates were higher in areas where grazing sheep were present.

With grazing and habitat management in mind, could these vast areas that wind farms cover offer an opportunity for reptile conservation?

Clay snake models are one simple but effective approach for measuring attack rates. Suzanne Collinson, from the University of Cumbria and the Cumbria Amphibian & Reptile Group, discussed another interesting technique that she used when studying Slow Worms Anguis fragilis. She used photo identification to study the size and dynamics of a Slow Worm population in a churchyard in Dalston, Cumbria. Slow Worms are a UK Biodiversity Action Plan priority species and protected under the Wildlife and Countryside Act 1981 due to their overall decline, therefore this population in the village of Dalston is of great interest, especially to the locals. Due to their morphology and cryptic behaviour, mark and recapture is a difficult method to use to survey Slow Worms. In addition to this, the markings on the neck and chin of a Slow Worm are unique to the individual and so, photo identification could offer a viable monitoring method.

In order to take a photograph of an individual, the Slow Worm would be placed on a clear tray, enabling photographs of the Slow Worm’s ventral surface to be taken quickly. The Slow Worms were found at various shelters or ACO’s (artificial cover objects) that were positioned across the churchyard. Suzanne also measured the body length of each new individual that she photographed and recorded the ambient temperature and the number of ant nests and snails present at the ACO. Suzanne counted 25 individuals in total (the original population estimate was 18) and found that as temperatures increased, Slow Worm encounters decreased. Ending on this note, Suzanne discussed the potential implications of climate change and how future monitoring will be necessary to understand what these future impacts could be on the population.

On both days there was a choice of five different workshops, all on very different topics, that we could take part in. On the first day, we attended ‘Managing habitats for conflicting species’ led by Jim Foster and Andrew Hampson from the Amphibian and Reptile Conservation Trust. Faced with a real-time scenario, we discussed in small groups the potential conflicts that could arise and what approach should be used to move forward – our scenario was based at the dunes of Sefton coast, and focused on the population of Natterjack toads that reside there. This was an interesting opportunity to hear what lessons had been learnt from previous conservation projects and how this knowledge can be used for effective conservation planning in the future.

Of course, this is just a snapshot of the range of topics discussed over the duration of the conference. Hearing first hand what organisations such as the Amphibian and Reptile Conservation Trust and Amphibian and Reptile Groups of UK are doing to conserve reptile and amphibian species in the UK, plus the ongoing research on both British species and those of other countries was fascinating.
