No Mow May 2024: An Update

Each year, Plantlife launch their national campaign of #NoMowMay. This initiative encourages people across the UK to allow their garden lawns to grow wild in the spring, providing vital habitats for many species. Here at NHBS, this is our fourth year taking part – each year in awe of the diversity of species in our lawn. Find our previous No Mow May blog posts on our conservation hub. Here, we give an update on the species we saw throughout last month.

The wilder lawns that develop during No Mow May provide a haven for invertebrate species in our gardens. At NHBS, we saw a whole host of insects in and around our lawn last month, from wasps to weevils and Green-veined White butterflies. Other highlights have included:

A Small Yellow Underwing (Panemeria tenebrata) – a diurnal moth species frequenting meadows and grassland.

Mayfly (Ephemera vulgata) – found near rivers and areas of freshwater between May and August.

Volucella bombylans – a bumblebee-mimicking hoverfly common throughout the UK.

Beautiful Demoiselle (Calopteryx virgo) – a damselfly with a striking blue, metallic body found near rivers and streams.

And some beautiful wildflowers, including Red Clover (Trifolium pratense) and Perforate St John’s Wort (Hypericum perforatum). Here are some of our favourites:

The Southern Marsh Orchid (Dactylorhiza praetermissa) – the most common and widespread of marsh orchids, features spectacular purple petals.

Bee Orchid (Ophrys apifera) – named for its mimicry, the Bee Orchid self-pollinates due to a lack of appropriate pollinators in the UK. The specimen on our lawn has yet to bloom (left), but we have a striking image from last year showcasing the mimicry of this species (right).

Cuckooflower (Cardamine pratensis) – also known as ‘Lady’s-smock’, this flower is one of the first signs of spring, often found near riverbanks, wet meadows and grassland.

Germander Speedwell (Veronica chamaedrys) – considered a ‘good luck charm’ for travellers, this plant has a beautiful blue flower and is found in meadows, woods and hedgerows across the UK.

Our Product and Purchasing Manager, Mark, has documented the progress of his local park during No Mow May. Towards the end of the month, the green expanse had varying lengths of grass and plenty of wildflowers, encouraging pollinating species – a great example of how local councils can boost biodiversity in public spaces.

And our Sales and Marketing Manager, Adam, has grown his lawn throughout May creating a corridor for local wildlife brimming with wild buttercups, dandelions and many other self-seeded plants.

No Mow May is a fantastic initiative to engage with, attracting homeowners, businesses and local councils with its wealth of benefits. If you have enjoyed taking part, then Let it Bloom June could be a great opportunity to continue supporting your garden wildlife. This scheme simply involves continuing the No Mow May philosophy throughout the summer with less garden maintenance. You may choose to allow your entire garden to grow wild or leave some areas untouched for wildlife.

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.

Toads in the Roads

It is in the earliest months of the year, when the weather turns milder and deeply saturating rains arrive, that adult toads, frogs and newts begin to emerge from their wintering hibernacula and make their long-standing annual journeys to the waterways in which they breed. It’s an ancient way of life for amphibians and a behaviour that pre-dates humankind by millennia.

Roads are a relatively new addition to the landscape by comparison. A blink of an eye in toad evolution. They frequently bisect the paths that amphibians must navigate in order to reach their ancestral ponds. Being relatively slow-moving, small, and cryptically coloured, amphibians are incredibly vulnerable on tarmac roads. As such, it is estimated that two tons of toads are killed on roads each year in the UK.

This February was one of the warmest and wettest on record in England, and it felt every bit of it. Despite the gloom of early darkness and torrential rain, I was thrilled to sign up and join an enthusiastic local volunteer group of Toad patrollers, deep in the Devon laneways, to learn what work is being done to mitigate our impact on the amphibians currently making these critical journeys.

The Toads on Roads project was spearheaded by the amphibian charity Froglife over twenty years ago. Volunteers that are involved in the project put in considerable effort each year to monitor known and established toad crossings around the country. These are the places where toads gather in their largest numbers and are at significant risk of being run over in their attempts to reach spawning ponds.

The group I joined have, for a number of years, been protecting an intersection where three roads meet beside a large pond. As we gather in high-vis vests at around half five in the evening, it’s already fully dark. We’re wearing latex-free gloves and bearing large white buckets. The pond is swelling up either side of the road, flooding the tree roots in a muddy soup. The rain falls intermittently and, sure enough, a proud collection of male toads is already eagerly lining the roads awaiting the females.

We walk along the lane counting the toads we find and placing markers near them that are more visible for passing cars than the toads themselves are. It’s not such a busy road, but it is narrow and steeply enclosed between old earthen hedgerows that cars and tractors have clipped away over time, resulting in an overhang that the toads are incapable of climbing. Often, they become trapped along the lane. Where we find them in a predicament, we watch to observe the direction of their travel, and if the cars come, we gently lift the toads off the tarmac and place them in the verge where they appear to be headed.

A few drivers who come by slow down and ask what we’re doing. Many seem intrigued by the response, often vowing to take care as they go on. I’m told this is an improvement. As awareness of toad crossings and the work being done to monitor them increases, people are more understanding, though I’m assured there’s still animosity from some drivers who feel inconvenienced.

During some of the evenings on the patrol we encountered beastly weather; driving rain and flooded roads; and I marvelled at the dedication of the volunteers and their care for the amphibians crossing the roads. I learned that more people are approaching Froglife to get involved and that, due to increased awareness and publicity, the plight of toads is reaching more and more would-be patrollers. There have also been successful cases of temporary road closures to divert traffic during the heights of toad migration in the UK this year.

It’s a complex web of challenges that contribute to amphibian population declines – not just nationally but globally. Land-use intensification threatens our waterways with myriad pollutants and our roads and construction projects fragment vital habitats or obliterate them entirely. It’s heartening that awareness is building. It has been such an inspiration to me to learn there’s a network of enthusiastic and caring volunteers out there in the winter nights, working at limiting the damage to amphibian populations, championing these remarkable and charismatic animals, and building hopeful connections in local communities while doing so.

If you feel call to get involved, visit the Froglife website where you can learn more about local toad crossings. There’s also abundant information on ways that you can make any local green spaces or gardens more amphibian friendly, such as making ponds, allowing wilder patches and encouraging greater invertebrate diversity.

The Big Garden Birdwatch: NHBS Staff Results 2024

The RSPB’s 45th Big Garden Birdwatch took place between Friday 26th and Sunday 28th January 2024. This annual event is one of the largest citizen science wildlife surveys in the UK and helps us gain an understanding of how our garden bird populations are changing in abundance and distribution over time. Over half a million people took part in last year’s event, recording a total of 9.1 million birds. House Sparrows took first place, despite a gradual 57% decrease in sightings since the first Birdwatch Count in 1979. They were closely followed by the Blue Tit and Starling.

Although the Big Garden Birdwatch has finished, there is still time to submit your results on the RSPB website by the 18th February, or by post before the 13th February. Even if you didn’t see anything, it still counts!

With birds being faced with an increasing number of challenges each year, it’s more important than ever to make your garden and outdoor space wildlife friendly. This can include installing bird feeders or tables which provide an important food source throughout the winter months when natural food sources are scarce., You can also provide clean, fresh drinking water in shallow containers such as bird baths or saucers, and install nest boxes for breeding in the spring. Also, don’t forget to regularly clean and maintain your feeders and baths as this helps stop the spread of disease. Head over to the RSPB website to find out more about how you can help your garden birds.

No Mow May 2023

In Spring 2023 NHBS have, for the third year running, participated in Plantlife’s #NoMowMay initiative. We’ve requested that the grass areas around our premises are spared from mowing for the duration of the month of May, allowing a host of flowering plants to expand and in some cases complete their flowering cycle.

May is a vital time in the lives of many flowering plants, as they grow up in a rush after the winter months of dormancy in the soil to meet the pollinators upon whom they rely for regeneration. In our gardens and municipal green spaces, we tend to keep lawns tamed and green by regularly mowing and clearing out flowering plants in favour of a neat and uniformed low-cut grass. This has benefits for us in some of our recreation activities, but it wreaks havoc on our ecosystems. If pollinating invertebrate species can’t find the flowers they rely on, they disappear from an area, which also has a knock-on effect on the species that need the invertebrates as a food source, and the flowering plants that need them to spread their pollen and reproduce. Over time, this fragments habitats and drives down both biodiversity and abundance of species.

So, by committing to #NoMowMay, no matter what size of a green space you have, you offer real potential for reconnection between plants and their pollinators, which in turn supports a greater number of birds, bats and other mammals large and small, including us!

This year, after quite a wet spell of late winter weeks with cold winds blowing through, May arrived with a warm embrace of pleasant sunshine that supported a quick growth of many flowering plants. Early flowers here were the Cut-leaved Crane’s-bill (Geranium dissectum), Common Vetch (Vicia sativa) and Cuckooflower (Cardamine pratensis), that spread rigorously through the grass along with a matt of Creeping Buttercup (Ranunculus repens). As soon as mowing ceased Daisies (Bellis perennis) and Germander Speedwell (Veronica chamaedrys) flowered throughout, alongside Dandelions (Taraxacum officinalis), Spotted Medick (Medicago arabica) and Herb-robert (Geranium robertianum). Many of the species present this year are listed in our species tally from last year (See our No Mow May 2022 blog here for a more comprehensive plant list).

This year, it’s been a real wonder to witness some more of the invertebrate life across our May meadow. In the still warm sunshine, we’ve seen a fair few bumble, honey and solitary bee species dashing by, some impressive wasps and flies (including scorpion flies) and, owing to our riverside location, we’ve started seeing Mayflies and Damselflies in the last week or so. There’s been some fleeting glimpses of spiders sunning themselves on the walls and walkways and a beautiful Nursery Web spider (Pisaura mirabilis) touring the vegetation.

Along the edges of the plot here where trees and shrubs tower up, surrounded by Cleavers (Galium aparine), Brambles and Docks, we’ve found a few small green weevils (that we’re struggling to ID beyond the subfamily of Entiminae) and Red-and-black Froghoppers (Cercopis vulnerate) – plus, a short distance away we were delighted to encounter an incredible Horned Treehopper (Centrotus cornutus)! There’s also been a regular meeting of Iris Weevils (Mononychus punctumalbum) on the blue marking flags we had put out to highlight points of particular interest.

We’ve had regular visits from Orange-tip butterflies (Anthocharis cardamines), Holly Blues’ (Cauchas rufimitrella), Peacock (Aglais io) and Green-veined White Butterflies (Pieris napi) throughout the month, and, when the afternoon sun has been particularly strong, a handful of beautiful Meadow Long-horn moths (Cauchas rufimitrella) have gathered in a shimmering dance around the blooming Cuckooflowers. We’ve also been treated to some short appearances of a Burnet Companion moth (Euclidia glyphica) as they quickly nipped between the vetch flowers.

We’re hoping that we can leave the plants a little longer into June again this year, as there’s still some remarkable species yet to flower, and it’s such a delight to see so many invertebrates thriving alongside the plants in this wayside patch. Suffice it to say if this place had kept to the same mowing schedule as some other local verges, there’d be little or no opportunity for the plants or their pollinators to proliferate or regenerate, and that’s without even considering the benefits to us humans of allowing and encouraging this dynamic ecosystem. Small contribution as it may be in the grand scheme of things.

We hope you’ve been inspired to join in with Plantlife’s #NoMowMay this year too, or perhaps through June, and next summer too! We sell a wide range of handy books for identifying wild plants and animals, and there’s a growing number of books that are helpful resources for gardening for wildlife!

No Mow May 2022

Just days into May the flowers begin. Image – Oli Haines

Throughout May 2022 Plantlife have once again made their impassioned annual plea for garden owners across the UK to resist the urge to mow lawns and tidy up their gardens and to join in with #NoMowMay. It’s a simple enough premise to leave grassy areas alone for a month, and it has huge benefits for biodiversity at this time of year to do so, giving a wide variety of flowering plants a chance to bloom early in appeal to our rich network of vital pollinators.

As in 2021, we here at NHBS have participated this year by letting the grassy areas on our premises flower and the results were quickly quite astounding. Within days there was a carpet of daisies and dandelions, Germander Speedwell and Black and Spotted Medic, and, as the month progressed and we explored further, the picture grew more and more complex. Tangles of Common Vetch, Creeping Buttercup and Common Mouse-ear proliferated, and tall fronds of Beaked Hawk’s Beard, Ribwort Plantain and Prickly Sow-thistle appeared. Hidden deep within a mixed mat of grasses the miniscule flowers of Cut-leaved Crane’s-bill, Thyme-leaved Speedwell and Scarlet Pimpernel flourished and, at the lawn edges, tall stands of Garlic Mustard and Cleavers towered over the last of the seasons Bluebell flowers.

It can still feel strangely radical to let an area of public space, or even a private garden, to grow wild. Perhaps it can feel like going against the flow to sit back and not mow or trim the grass, and to embrace a modicum of wild chaos. Much of our wildlife relies on the flowering plants that we suppress with our tidiness and our control of lawns. Multitudes of beetles, bees, ants, moths and butterflies have evolved alongside plants that, given half a chance, can still thrive in our green spaces. No Mow May offers us a glimpse into this rich relationship, this conversation in time, and it provides a lifeline. One flower that showed up in our lawn here, by way of an example, is the Cuckoo flower or Lady’s Smock, a light and elegant pink flower of grasslands that is almost exclusively selected by the Orange-tip (and Green-veined White) butterfly in spring to lay their eggs on, as it feeds the caterpillars when they hatch. Growing up to 50cm in height its reach is well within the mowing range.

In addition to the No Mow May initiative, Plantlife have also introduced Every Flower Counts, a citizen science survey that asks participants to count, record and report back the flowers found in a single metre squared patch of lawn . This will enable them to gather important data on the impact that leaving areas to grow can have on abundance and biodiversity.

As May winds to a close, species are still beginning to emerge in our lawn ready to flower in June: Spear Thistle, Oxeye Daisy, members of the Carrot family and, with a final flourish of the month, a Bee Orchid slowly opens its blooms right by the footway, surprisingly cryptic until you meet it at ground level.

We hope that we can leave our grass uncut for a little longer so we can see who’s still there to flower, and that those of you who have participated in No Mow May may feel inspired to do the same.

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.

No Mow May 2021

Plantlife’s “No Mow May” campaign asked gardeners around the UK to lock up their lawnmower and let the wild flowers in their lawn bloom. This simple change in mowing has been shown to bring huge benefits, providing a feast of nectar for our hungry pollinators.

At the end of May, Plantlife opened its “Every Flower Counts” survey, a fun and easy way to discover how many bees the UK’s lawns can feed. People from all around the country took part, recording the different flowers which had bloomed on their lawn. These results will then be compiled to produce the National Nectar Score.

Here at NHBS we were delighted to take part in No Mow May, with a number of our staff members saying “no” to the mow in order to help our bees, butterflies, and wildlife!

You can find out how we got on below:

Outside the NHBS building

The grass outside the NHBS building was left unmown during May, allowing lots of daises, dandelions and speedwell to bloom. This created a beneficial space for a variety of insects and pollinators.

Nigel

Nigel turned his lawn into a wild haven, allowing an abundance of dandelions and forget-me-nots to blossom.

Nigel also contacted the local council, persuading them to set aside an unmown patch of grass at a local cemetery – an area usually mown twice a month from March to November. The photo below shows the contrast between the the unmown area and the area which continues to be mown and strimmed. As shown below, leaving an unmown patch has allowed a number of daises and dandelions to sprout up.

Oli

Oli’s garden remains wild year-round, attracting a variety of plants and wildlife. Most recently, his garden saw the arrival of this rather impressive-looking slow worm!

Natt

Natt’s lawn was left unmown during May, with the long grass helping to provide habitat for a variety of different insects.

Elle

Elle’s garden saw the blooming of these stunning buttercups, ideal for pollinators and other wildlife.

Marie

Marie’s lawn was also left to grow during May, allowing lots of lovely daises to sprout up.

Angeline

Angeline’s dog Freya enjoyed exploring a field of buttercups which had been left untouched during May.

Butterfly Conservation Moth Recorders’ Meeting 2021

On Saturday 30th January I attended the first online Moth Recorders’ Meeting of 2021, organised by Butterfly Conservation and chaired by Dr. Richard Fox. Although it was still a couple of months from the time when people would be putting their traps out in earnest for the spring/summer influx of species on the wing, there was a poignant and reflective look back on the strange year that had just been. It was also noted how, through national lockdowns and social distancing measures brought on by the global pandemic in 2020, there had been an indisputable increase in appreciation for the importance of moths and butterflies. It was mentioned that, at the time of the meeting, there had been 14 million impressions across social media platforms using the hashtag #mothsmatter and an insatiable appetite for the Butterfly Conservation hawk-moth identification sheets and for moth traps!

The impact of lockdown on moth recording

The first talk of the morning from Dr. Zoe Randle discussed the connection to wildlife that was kindling in our homes and gardens through 2020, and reported that there was, in the last year, a 62% increase in records submitted to Devon Moth Group, and a 72% increase in recorders! This speaks volumes about a growing awareness and appreciation for moths and provides vital data on the bigger picture of how our native species are faring. There is also evidence to suggest that 2020 was a boom year for the Jersey Tiger moth, with abundant national sightings indicating that the species could be expanding its range further north.

Inevitably, this influx of records requires consolidation by county moth recorders on local levels in order to feed them into the national dataset, and it was these hard working volunteers who were the focus of Zoe’s talk. Specifically she discussed the best ways to support them in their rolls and investigated the demographics of county moth recorders alongside details on the submission status at the time.

The pandemic has resulted in a huge increase in submitted records and email correspondence

This need to streamline the information in support of county moth recorders was echoed and advanced by Dr. Katie Cruickshanks who was next to speak.

Katie spoke about the benefits of this widening pool of public participation suggesting that, not only does it expand our understanding of national biodiversity, but it also connects us meaningfully with wildlife and has positive effects on our own personal wellbeing. Public perception of moths and butterflies is improving through events like Butterfly Conservation’s Big Butterfly Count, which encourages people to log the species they see in their local patch for a set period of time using a dedicated app. The wealth of sightings that come through apps like this and iRecord – alongside information gathered from social media and anecdotal sources – has meant that the recording process is a vast and time consuming activity for volunteers. Katie spoke on how this process currently works and speculated on how it might be streamlined moving forwards.

Data from citizen science projects and moth recording is vital for making conservation decisions, compiling atlases and for directing policy.

As a follow up to the publication of the Atlas of Britain & Ireland’s Larger Moths at the end of 2019, Dr. Richard Fox spoke next on the state of Britain’s larger moths.

The compilation of data for the new State of Britain’s Larger Moths 2021 report was an ambitious project and took into account 50 years worth of accumulated information, providing a unique understanding of moth population trends. To date, it represents the longest-running standardised monitoring of insect populations anywhere in the world. The study divides data to create a more accurate picture of the abundance and distribution of larger moths across the country, and takes into account northern and southern records separately to build a stronger idea of where increases and declines in species numbers are occurring. Overall abundance of larger moths caught in traps over the 50 year survey period points to a concerning 33% decline across the country (with a southern decline of 39% and a northern decline of 22%). There is, however, evidence that moth species in the UK have increased their distribution by 9% over a 47 year period (1970-2016).

Changes in moth abundance over a period of 47 years

Dr. Fox also talked through the understanding we now have of distribution indicators for different habitats including woodland, grassland, moorland and heathland. These indicators suggest that “loss and deterioration of wildlife-rich habitats is probably still the main cause of population declines”.

Distribution indicators for several habitat types

There are, however, many nationwide projects working to correct for this and enrich habitats once again; such as the Highways England roadside verge scheme managed by Butterfly Conservation’s Dr. Phil Sterling, which is working to create improved grassland habitat corridors along roadsides.

Next came a passionate report on moth trapping through lockdown from Luke Phillips (Dorset RSPB). In this personal account of how national restrictions pushed him to connect more keenly with wildlife locally, Luke described some of the star species that visited his patch throughout the long spring and summer season of 2020, including a scarce Alder Kitten (Furcula bicuspis) and an unusual Birch Mocha variant (Cyclophora albipunctata).

Luke has been involved in a number of public engagement activities that encourage individuals and families to embrace the wildlife in their own spaces, including nationwide moth trap reveals and The Big September Sleepout, which sees hundreds of families across the country meeting to camp in wild places and witness the wildlife around them. In the last year these activities have still occurred, but with participants camping in their own gardens and spaces (in accordance with social distancing measures) and then convening virtually to discuss their findings. The uptake on these activities has been really encouraging and, besides the obvious benefits to wellbeing of connecting people and wildlife in these ways, these moth mornings and camp-outs also produce lots more data for Butterfly Conservation!

The final speaker of the day was Dr. David Wagner, a systematist and lepidopterist from the University of Connecticut, who spoke about Insect Decline in the Anthropocene and How Moths are Faring. David discussed our current understanding of anthropogenic impacts on climate through habitat destruction and the intensification of agricultural practices around the world, and how their knock-on effects impact on parts of the tropics that are still feeling little to no direct harm from these practices. As a result of spreading drought conditions through the world’s grasslands and cloud bank diminishment in the tropics it is clear that insect abundance is in decline (although some species are faring better than others, and even increasing in numbers).

Cloud bank diminishment in the tropics over a period of 30 years

David pointed out that the most concerning thing is situations where there are declines in common/abundant species in parts of the world where there is little to no anthropogenic impact. This indicates a systemic problem that we can’t yet see. But in the unique case of the United Kingdom, where we have a vast archive of data collection and large levels of public involvement in monitoring, we can see more clearly the impacts of emerging anthropogenic factors, and this can inform our understanding to a certain degree. This depth of research has still not been realised in most parts of the world which means our global view of how insect populations at large are faring is incomplete.

The morning wound up with an important message to anyone passionate about moth and insect conservation: keep working at collecting the data, keep submitting records, lend your voice as an ambassador for insect surveying where you can, and continue to learn and encourage learning.

An important checklist for anyone passionate about insect conservation
