John Wilkinson, Science Programme Manager with ARC Trust, on amphibian conservation

The Amphibian Survey and Monitoring Handbook is the latest volume in the Conservation Handbooks series, tackling all aspects of amphibian survey. Author John Wilkinson is Science Programme Manager with The Amphibian and Reptile Conservation Trust (ARC Trust).

What is your background in herpetology and what have been some of the highlights of your work?

After university, where my undergraduate dissertation was on amphibian diversity in Northern Italy, I worked on some short-term academic contracts before getting a job coordinating the international response to global amphibian declines with the IUCN SSC Declining Amphibian Populations Task Force (now the Amphibian Specialist Group). I learnt a lot there about the complexities of amphibian declines and the importance of systematic surveys.

A recent highlight of my conservation work was the discovery, building on my PhD research, that toads on the Channel Island of Jersey are a completely different species than those in mainland Britain – they’re actually Bufo spinosus, a species that evolved in Iberia millions of years ago whilst English toads were spreading out of the Balkans. Most importantly, their ecology is very different and they therefore require different conservation measures!

Could you tell us about any major trends that have been discovered by the monitoring schemes you have been involved with?

Part of my work is coordinating the UK National Amphibian and Reptile Recording Scheme (NARRS), which has so far highlighted the serious declines of British adders and changes in the relative abundance of our smaller newts (palmate newts seem relatively more widespread than in former national surveys, possibly indicating a change in quality in Britain’s ponds).

How does a decline in amphibian and reptile biodiversity affect ecosystems?

These creatures are hugely important for many ecosystems as they occupy key niches in the middle of the food chain: as well as being important prey for a wide range of species from otters to marsh harriers, they are themselves important predators, consuming millions of pest invertebrates every year. Healthy amphibian populations in particular are therefore important to human food production and population losses have economic implications as well as resulting in more pesticide use.

What can be done to reverse this decline which is pervasive worldwide?

Though numerous factors cause declines, habitat loss and fragmentation is still the most significant problem. Local planning must take into account the need to keep breeding and foraging habitats connected to boost population resilience – as well as incorporating habitat into landscape-level schemes. At ARC, we’re leading the way on using predictive modelling and GIS techniques to model the effects of development and produce the best outcomes for amphibians (and other species).

If you were given the chance to implement one policy, today, in support of amphibian & reptile conservation, anywhere in the world, what would it be?

It would be easiest to come up with a list! I will, however, highlight a problem in the UK: our widespread amphibians have NO real protection under the law – though the NERC act outlines a “duty to consider” declining species like toads in development. ALL our amphibians and reptiles need full legal protection which is enforced, and which includes their habitats – otherwise developers can continue to fill in ponds and disconnect populations at will. Our widespread species are really a lot more threatened than the most highly-protected ones (the effects of this can already be seen with recent declines in the adder and toad)!

How can the general public get involved with projects to help their local herpetofauna?

Join a local Amphibian and Reptile Group (ARG) and ask them if they can participate in NARRS, as a group, to ensure their local information is considered nationally.
Build a pond and make a compost heap.
Volunteer to help create and manage habitats through ARC and/or other bodies such as local wildlife trusts.
Always report sightings of amphibians and reptiles (see www.recordpool.org.uk) – this will help their conservation.
Take local councils, conservation bodies (or anyone else!) to task when any local sites are planned for development or disconnection!

Update for Wildlife Acoustics users: SMX-U1 and SMM-U1 Microphone Weather Protection

We have received the following message from Wildlife Acoustics which contains essential information for users of the SMX-U1, SMM-U1, and SMX-Horn microphones.

Due to a small number of microphone failures occurring from wind driven rain in our continued testing, we have decided to include protective windscreens with all future microphone shipments. We have also decided to provide windscreens to all existing SMX-U1 and SMM-U1 microphone customers at no charge. Additionally, we will be providing a larger windscreen for the SMX-Horn directional attachment, and again providing these at no charge to existing customers.

Though we did not experience microphone failures in our initial rigorous weather testing of the microphones, some recent failures observed in the field indicate that the microphone element may still be at risk of damage in the event of extreme weather. The main concern is specifically high-velocity wind-blown rain resulting in water spray entering the FG sensor causing damage to the membrane and/or electronics inside. The risk is greater when deployed with the ultrasonic horn attachment. Though we have seen issues with only a handful of microphones, we recommend that you use windscreens for long-term deployments in all areas susceptible to heavy wind driven rain out of an abundance of caution. We view the use of windscreens as a preventative measure to avoid any chance of damage to the microphone element when used in severe weather. For short-term deployments with predictions of less severe weather and in dry climates, you can avoid using windscreens.

The windscreens will attenuate ultrasound by only a few dB when dry. However, they will block most ultrasound when soaked with water, until they dry. Drying time can vary significantly based on temperature, humidity and wind. Given this information, we leave it to you to decide the best course of action for each deployment.

wa-windscreen-1

Secure the windscreens for the SMX-U1 and SMM-U1 microphones with the included C-clip. Make sure there is an air gap between the windscreen and the microphone as shown below. (Do not pull the windscreen down tightly).

For the SMX-Horn directional attachment, secure the large windscreen with the included zip-tie as shown below. Exact positioning is not important.

wa-windscreen-2

If you have purchased one or more SMM-U1, SMX-U1 microphones or the SMX-Horn attachment from NHBS you do not need to do anything, we will send your microphone covers to you free of charge in the next few days.

Sweden’s first regional dragonfly atlas – interview with author Tommy Karlsson

Tommy Karlsson, author of Östergötlands Trollsländor [Dragonflies in Östergötland]

Congratulations on the book and on publishing the first regional distribution atlas for dragonflies in Sweden. What is your background in natural history? Have you always been interested in dragonflies?
Thank you very much! I am a biologist and work since 2005 at the department of Nature Conservation at the County Administrative Board of Östergötland, mainly with action plans for threatened species. I have always been interested by natural history, and as a kid I liked to collect larvae of dragonflies, stoneflies, mayflies and other limnic insects. However, my interest for imago dragonflies and identification of species started during my biology studies, about 2002-2003.

For those who may not be familiar with the natural history of Sweden, what sort of place is Östergötland in terms of biodiversity and landscape?
Östergötland is situated in south east Sweden and covers 14,500 km sq. It is situated in the boreonemoral vegetation zone and can be divided into four natural geographic regions: the southern woodlands, the plains, the archipelago, and the northern woodlands. The woodlands and the archipelago mainly consist of coniferous forests, while the plains mainly consists of intensively cultivated agricultural land. The woodlands have great numbers of lakes and mires, while the plains are very poor in water. The main part of Östergötland is lowlands, but in the southern woodlands there are considerable areas above 200 m.a.s.l. The bedrock in the county is mainly acid but in the western part of the plains there is an area of Cambro-silurian calcareous rock. During the last glaciation, calcareous material was dispersed southwards, resulting in calcareous soils in some parts of the southern woodlands with granite bedrock. As a consequence of bedrock and soils you find mainly oligotrophic and dystrophic waters in the northern woodlands, eutrophic waters in the plains, and a mix of oligotrophic, dystrophic and mesotrophic in the southern woodlands. Östergötland, along with other southeastern regions, is one of the most species-rich regions in Sweden considering invertebrates due to its relatively warm and dry summers. It is well known for its considerable areas with hollow oaks and the saprolyxic fauna and flora associated with them.

How do you co-ordinate a project like this, with 150 volunteers over the course of five years (2008-2012), and what were some of the highs and lows?
It worked out very well since all was based on voluntarism. After getting initial information about surveying and identifying dragonflies, the participants could work quite independently. Most of the communication with the participants was made through e-mail. In addition, several activities were organized: kick-offs every spring, survey courses and excursions during summer, and reporting courses during fall. Many of the participants had no experience of surveying dragonflies before, and the fact that we managed to get so many volunteer amateurs out surveying dragonflies was one of the highlights of the project. Furthermore, the participants were a heterogenous group in terms of age and gender, and not only older men which is common in entomological contexts.

In the study you make comparisons with 10 other regions in Europe. What conclusions have you been able to draw through these comparisons?
Yes, I compare Östergötland with some other European regions where dragonfly surveys have been performed. Most of the regions have more species than Östergötland because they are situated south of Östergötland. On the other hand, Östergötland has two species which generally are missing in the other regions: Coenagrion johanssoni and Aeshna serrata. When comparing the species the regions have in common, the frequency for some species differs a lot between Östergötland and the other regions. Östergötland is distinguished by the fact that species classified as red-listed and/or decreasing in Europe occur more frequently in Östergötland than in most of the other regions. Particularly Coenagrion armatum and Leucorrhinia caudalis can be pointed out as much more common in Östergötland. Thus, Östergötland has both a national and international responsibility for these species, together with A. serrata, Aeshna viridis and Nehalennia speciosa. The reason for this is that important habitats for these species, such as bog ponds and mesotrophic lakes are naturally more common in Sweden, and that the exploitation of waters in Sweden has not been as severe as in central Europe.

Östergötlands Trollsländor [Dragonflies in Östergötland]

What were some of the other significant findings of the project?
Probably because of global warming there is an ongoing change in the European dragonfly fauna where several southern species have expanded rapidly northwards and some northern species have retreated. In Östergötland the establishment of Lestes virens and Ischnura pumilio has been documented during the survey. L. virens was observed for the first time in the county in 2005 and, during the period 2008-2012, was found at several new localities every year. I. pumilio was first noted for the Östergötland in 2012.

And what is next for you and for the Östergötlands Entomological Society?
This year I have got the assignment to co-ordinate Sweden’s monitoring of the dragonflies species listed in the EU’s habitat directive. It will be very nice to work professionally with dragonflies and I have learned a lot about these species and dragonfly monitoring during the survey in Östergötland. I started this work last week with a field study of Ophiogomphus cecilia, a species only occurring in some few unregulated rivers in the very far north of Sweden. Concerning the Entomological Society in Östergötland, we have discussed the possibility of starting up another voluntary survey of some other easy identified insect group, e.g. shield bugs or grasshoppers, but nothing is ready to start yet.

Supplier Interview: Jack Skuse of Ambios Ltd

Ambios are an educational charity based a mile or so down the river Dart from NHBS at a tenant farm on the historic Sharpham Estate. They provide conservation education, inspiration and training to a wide range of people at their farm, Lower Sharpham Barton. Over the last few years Ambios and NHBS have worked together on a range of products including the NHBS Kent Bat Box and reptile survey felts. The Lower Sharpham Barton site is managed by Jack Skuse.

Tell us a little about your organisation and how you got started.

Ambios Ltd are a nature conservation training organisation established in 2001. We aim to offer inspirational education, practical action, science and technology training and volunteering opportunities in the UK and EU. In partnership with Robert Owen Communities (ROC), a charity based in South West England supporting adults with learning disabilities, we run a farm on the stunning Sharpham estate outside Totnes, Devon. The aim of Lower Sharpham Farm is to use farming as a way of improving biodiversity, whilst offering people the chance to engage with wildlife and the outdoors – the farm runs as a care farm and base for our residential training activities. In partnership with UK and EU nature conservation organisations people can stay and learn at our farm, or in one of five EU countries including Norway, Hungary and Portugal. The people who engage with our farm (EU trainees, adults with learning disabilities) produce wildlife boxes for sale by NHBS.

What challenges do you face as an organisation working in the ecology/natural history sector?

There are a number of challenges we face, primarily relating to funding. We have historically accessed funding to run training for the next generation of wildlife professionals, as well as engaging and stimulating nature conservation-related provision for disabled people. This funding is proving harder to access, and we are aiming to diversify into a number of areas that generate revenue: training and volunteering placements where the learner pays, or is part subsidised by grant funding; wildlife experiences where learners can stay in our yurts for a number of days and gain employability skills and experience hands-on nature conservation projects, including bumble bee research, bird and badger surveys and practical habitat management; and producing, adding value to, and selling the products of the farm including organic beef, lamb, and eggs along with the wildlife boxes (typically made from wood sourced from the Sharpham Estate!).

What do you consider the most important achievement of your organisation in recent years?

To still be here 15 years later! We are proud of our legacy, and of the number and range of people who have benefited from our training, along with the wide and diverse network we have established here in UK and across EU. The farm tenancy is a leap of faith and grounds us in place and we are proud of the partnership with ROC and of the opportunities created here, and the potential available to us over the coming years.

What is your most memorable wildlife/natural history encounter?

I have seen wildlife around the world, and have strong memories of orca whales in Patagonia, and cobra snakes in Thailand (a close encounter whilst riding a bike). I was lucky enough to work with the Barn Owl Trust here in Devon, radio tracking barn owls whilst they fledged the nest for the first time. This close observation and appreciation of an enigmatic creature that is found here in UK was profound.

Ecologist Derek Gow on beaver reintroductions in the UK

Ecologist Derek Gow (The Derek Gow Consultancy) is the co-author of The Eurasian Beaver, published in January 2015. His involvement with Devon Wildlife Trust’s trial reintroduction and the Tayside beaver reintroduction makes him uniquely placed to discuss the topic of beaver reintroductions in the UK.

How would the presence of healthy beaver populations enhance the UK’s landscape and biodiversity?

In Eurasia and North America beavers are the keystone species around which all other wetland life revolves. Their simple dam building and tree felling activities trigger a whole range of complex changes in their surrounding environments which clearly result in greatly enhanced levels of biodiversity and biomass. In landscapes which are semi-natural the cascade of dynamic changes they produce harbours the potential for breathtakingly spectacular results, such as the return of the black stork. While in highly manipulated, human engineered environments they can literally breathe life back into the land.

You are involved with the Devon Beaver Project, which has created a test environment to see how reintroduced beavers would affect their local ecosystem. Can you tell us more about this project, and what results it has produced so far?

The initial stage of the Devon Beaver Trial was designed to evaluate from ground zero the impact of a beaver family in an enclosed area of wet-woodland of approximately 3ha. Between 2011 and 2015 the beavers created a series of approximately 14 major dam systems on a 200 metre length of a seasonally flowing water course at the northern end of the site. They maintain long dams in the winter when water is abundant and short dams in the summer when water is scarce. At the time of writing their impoundments are capable of retaining approximately 1000 tonnes of water, none of which would have seasonally remained on site without them. The return of the beaver has been accompanied by a proliferation of wildlife. Flowering and other vascular plant communities now abound on site. On warm sunny days meadow browns, marbled whites and a host of other butterflies flit through its open woodlands. Dragonflies and damselflies occur in ever greater numbers while amphibians such as common frogs have increased in numbers fiftyfold. Juvenile common lizards hunt through the deadwood understory while marsh tits, spotted flycatchers, greater spotted woodpeckers, tree creepers and redpolls hunt insects in the trees. Water fowl have moved into occupy environments which formerly did not exist. Red and roe deer jump the perimeter fence to drink in its pools.

It is an absolutely amazing project and a brilliant site.

What does a reintroduction look like in practical terms? Can you break down the logistics of species reintroduction?

Well if you ask the Germans its simple: you get lots of beavers – 40 plus per release, drive along the road, spot a likely location, and let them go. A crude system which works! Reintroductions in Britain are often subject to a large degree of politics, which can be frustrating as this is a species well understood throughout its natural range which simply offers so much. We could do much better. To date, beaver reintroduction has been a haphazard affair with major public spats between those that wish them to remain and those that are opposed – the history of the Tayside and Devon beavers demonstrate this well. Given that this species was last present in Britain outside of our living memory, it is assumed that licensed releases require a scientific demonstration of how this animal will impact a British landscape – as though it will be any different from what our European and American counterparts have already demonstrated. In realistic terms, in Britain an official reintroduction would involve a small number of animals, released into a specific site, with thorough scientific monitoring of impact and public opinion. Though we may take heart that beavers are now back in our landscape, the process to full restoration is likely to be slow and cautious.

What precedent does the approval of the River Otter beaver population set for reintroductions as a wider concept? Are we likely to see lynx roaming wild any time soon?

We need to learn to live with and tolerate beavers before I think we can accomplish anything more adventurous in Britain. If we can’t move forward with reintroducing this charismatic rodent that has such significant impacts on its environment, and can single-handedly do so much to restore our wetlands, then we need to be seriously realistic about our collective ability to accept top predators on this island – no matter how nostalgic or headline grabbing the notion of lynx may be.

What would you say to people who consider reintroduction to be somehow against the natural order of things?

When you consider our contemporary British landscapes and their land-use practices, which are entirely dictated by human activity, they represent little in the way of natural order. In truth they are not ecosystems and we are probably grasping at straws to even describe what’s left as tattered fragments blowing in the wind. Instead we have a wealth of isolated areas of biological richness, generally produced as a result of relict human activities which are difficult to maintain and increasingly vulnerable and fragile. Do we accept that these nature zoos are it, or do we try to foster and encourage a process whereby we change the pattern of the landscape we have made to make it better for people and wildlife alike? Reintroductions, where human activities have caused the past extinction or diminution of a species in Britain, are simply a tool we should employ with competent ease where the circumstances justify its use.

We recently heard the news about the successful litter of kits produced by the River Otter beavers. What did this news mean to you personally?

Brilliant!! It’s been a long time coming. Let’s move on now from these vital but small and isolated pockets of beavers and see the full restoration of this incredible species.

Nature’s Architect: The Beaver’s Return to Our Wild Landscapes is the latest book from leading nature writer Jim Crumley. The book explores the natural history of the beaver, and Crumley makes his case in favour of beaver reintroduction.

The NHBS guide to hand nets

The type of hand net you require can depend on a number of factors – including the type of environment you will be sampling, whether you will be using it for professional surveys or for pleasure (or perhaps both!), the type of sampling you will be conducting (i.e. pond dipping vs. kick sampling) and also your budget. Take a look at the different types of hand nets we supply to decide which is right for you.

Professional and Student Hand Nets

Professional Hand Nets are the original nets used by consultants, researchers and river authorities worldwide. In the U.K. they are approved and used by the Environment Agency, the Riverfly Partnership, the London Natural History Museum and the Salmon and Trout Association. They are suitable for both kick sampling and pond dipping in all types of aquatic environment and can last for 10 years or more, even with regular use.

Professional Hand Nets have a 250mm wide head and are available with a wooden or aluminium handle. Two-part and three-part sectional wooden handles are also available which can be unscrewed for transport or extended with extra sections. Frames with an aluminium handle are lighter and cheaper but are less comfortable to use, particularly in cold weather. Net bags to fit the Professional Hand Net are available in 1mm and 2mm woven mesh or 0.5mm and 0.25mm precision mesh. All bags are manufactured to international standards and mesh is guaranteed to stay the same shape and size, even under stress.

The Professional Hand Net is also available in a smaller Student version which is 200mm in width. This is designed to the same high quality as the larger Professional net but is ideal for educational use.

Lightweight Eco-Nets

The Lightweight Eco-Net has a strong aluminium frame which will withstand regular use both for kick sampling or pond dipping. Net heads are 160mm in width and 1mm and 2mm mesh bags are available to fit this frame. Bags attach to the head using industrial velcro, making them easy to replace.

Telescopic Pond Nets

The Telescopic Pond Net is designed for pond dipping only. Its lighter-weight construction means that it is not suitable for kick sampling, dragging along the bottom of streams or for sampling in dense vegetation. However, its light weight also makes it very suitable for students and younger users. The telescopic handle extends from 66cm to 115cm providing excellent reach. The net bag fixes to the frame using strong velcro.

Economy Pond Nets

For children or those that are new to pond dipping (or rock pooling) the Economy range of pond nets feature a plastic handle and frame and are available in three sizes. The smallest has a net head of just 15 x 13cm and a 76cm handle – perfect for small children. These nets are lightweight and affordable.

State of the Planet assessments

Ever since George Perkins Marsh’s seminal 1864 work, Man and Nature: Or, Physical Geography as Modified by Human Action, books assessing the state of the planet have become a staple part of the environmental literature. Marsh’s magnificent work spawned some valuable retrospectives, including Man’s Role in Changing the Face of the Earth (1956) and The Earth as Transformed by Human Action (1993).

But, since 2000, most of the really good stuff on biosphere and ecosystems science has been beyond the reach of many, behind the paywall of scientific journals (e.g. John Estes’ superb Trophic Downgrading of Planet Earth, Dirzo’s Defaunation in the Anthropocene, and Diffenbaugh’s Changes in Ecologically Critical Terrestrial Climate Conditions).

Following his 2012 paper in Nature, Approaching a state shift in Earth’s biosphere, Anthony Barnosky might well have followed the same route – but thankfully this brilliant and passionate scientist is also a believer in reaching out to a broader public: see his latest book, End Game: Tipping Point for Planet Earth.

Another leading light of planetary ecological assessment is the Swedish scientist, Johan Rockstrom, inventor of the ‘planetary boundaries’ concept, and author of perhaps the most influential peer-reviewed paper of the last decade (A safe operating space for humanity). He also has a new book just out, Big World, Small Planet.

Other notable recent publications on this theme include: The God Species (Lynas), The Sixth Extinction, an Unnatural History (Kolbert), the magisterial Millennium Ecosystem Assessment, Eaarth (McKibben), The Living Planet report 2014, (WWF), Here on Earth (Flannery), and Global Environmental Outlook 5.

BugDorm: Insect survey and rearing equipment

BugDorm have been supplying equipment for entomological research and teaching since they were established in 1995. Their products have become firm favourites with both professional and amateur entomologists and they are continually being developed to address the challenges encountered by field and lab workers everywhere. NHBS is proud to be a distributor of the BugDorm range.

Bugdorms — BugDorm Cages and Tents are available in a range of styles and sizes

For breeding and rearing insects, the BugDorm range of cages and tents offer a solution for every situation. Available in a wide range of sizes and mesh apertures, most have both entrance sleeves and zippered doors for convenient access. All pack flat for storage and transport. For rearing and studying insects in situ, insect rearing sleeves and bags allow you to contain leaves and branches within a temporary enclosure.

For field sampling, BugDorm offer malaise and migration traps, berlese funnels, emergence traps and bait traps. The ez-malaise and ez-migration traps use shock-corded poles to create a frame to which the net is clipped making them quick and easy to assemble. The ez-migration trap is cleverly designed with two collection areas, each with their own collecting bottle so that flight direction can be determined.

The innovative Slam Traps work on the same principle as the malaise traps, but can also be strung in a vertical chain to sample at different heights in the canopy. When used with the bottom collector (available separately), they will also collect insects such as beetles, that drop when they hit the trap. A four-headed version allows you to study migration patterns by collecting insects entering each of the four quadrants into separate collecting bottles.

The BugDorm range of insect net sets let you create your own net from a selection of frames, bags and handles. Net frames are collapsible and handles are telescopic with the longest options extending up to 530cm in length; ideal for sampling in the canopy.

Supplier interview: Volker Runkel of ecoObs

ecoObs are a small German company at the forefront of full spectrum bat call recording and identification. They produce the Batcorder 3, a highly optimised bat detector (each new microphone arrives with its own calibration factor to ensure that comparisons between units are valid) designed to consistently record bat calls of sufficiently high quality to make auto-identification possible. Calls can then be processed using ecoObs software bcAdmin 3.0, bcAnalyse 2.0 and batIdent. These enable the rapid and accurate identification of common bat species, speeding up the identification process by up to 70% and allowing users to focus more time on rare or interesting bat species. We asked ecoObs co-founder and managing director Volker Runkel to introduce the company.

Tell us a little about your company and how you got started

For my PhD thesis I developed a quite basic and rather well working solution for passive monitoring of bats. Already then I saw that automation in data collection as well as analysis was one of the keys to focus on, instead of all raw analysis work. We quickly realized there is a huge demand for such a solution. We then were lucky and found an engineer who partnered up with us and redesigned the hardware so it was power efficient, small and easy to use. The batcorder system was born.

What challenges do you face as a company in the ecology/natural history sector?

The sector is rather small and as a hardware producer we for example often have problems acquiring small quantities of parts. In electro-engineering small companies still require some hundred thousand parts while we ask for a mere thousand. Also the demand for devices is highly seasonal – 90% of orders arrive within a few weeks in spring when the bat season starts. On the other end, we have a very vivid and heterogeneous bat worker scene.

What do you consider the most important achievement of your company in recent years?

I think getting the batcorder and the analysis software out in the wild and thus pushing the whole field of passive monitoring and automated bat call identification to where it is now. When we started in 2004 no one believed it would be ever working, and now a rising number of devices and software exists.

What is your most memorable wildlife/natural history encounter?

Spotting and touching an Echidna in the wild!
