Conservation Volunteering at Prawle Point with Buglife

The NHBS team are passionate about nature and conservation, and to help them to get involved with local volunteer schemes, NHBS encourages colleagues to apply for up to three paid days each year to volunteer with a conservation project or organisation of their choice. Catherine Mitson, Assistant Editor for British Wildlife and Conservation Land Management, tells us about her time volunteering with Buglife and the bee species she is surveying.

The Long-horned Bee Eucera longicornis truly lives up to its name. The males sport bizarrely long antennae, and this in combination with their large size makes them instantly recognisable. Female Long-horned Bees, however, lack these oversized antennae and are more robust compared to the males, and can sometimes be confused with Anthophora (flower bees) species. Although the Long-horned Bee is a type of solitary bee and each female will dig her own nest hole, they tend to nest in aggregations in a variety of habitats, such as woodland rides and clearings, brownfield sites and coastal meadows. Here, however, we are focused on the south-facing soft cliffs along the South Devon coastline.

Prawle Point SSSI is a fantastic site for invertebrates, including the Long-horned Bee which can be found nesting in the cliff face or foraging on plants such as clovers, Bird’s-foot-trefoil and Narrow-leaved Everlasting-pea along the cliff top. What makes Prawle Point even more special is that it is the only site in the UK where the Long-horned Bee’s cuckoo, the Six-banded Nomad Bee Nomada sexfasciata, is known to be found. Like the bird, cuckoo bees lay their eggs in the nest of another bee, the host, and once hatched the larvae will eat the food stores that had been gathered by the host for its own larvae.

The Six-banded Nomad Bee is arguably the UK’s rarest bee, and relies on a healthy, viable population of its host. Sadly, due to the loss of flower-rich grassland, the Long-horned Bee has declined dramatically; once found in most southern English counties, its range is now restricted to the south coast of England and Wales with a few scattered inland sites. But a new project is hoping to turn the tide for the Long-horned Bee, the Six-banded Nomad Bee and many other rare invertebrates along the South Devon coast.

Life on the Edge 

Life on the Edge, funded by the National Lottery Heritage Fund, is an exciting new partnership with South Devon Area of Outstanding Natural Beauty, Buglife, National Trust, Torbay Coast and Countryside Trust, and the South West Coast Path Association. Focused on the South Devon coast between Berry Head and Wembury, Life on the Edge is aiming to restore viable populations of some the UK’s rarest invertebrates, including the Six-Banded Nomad Bee, by expanding and reconnecting the vital coastal habitats on which these species depend. There are 30 invertebrate species that this project will support, such as the Moon Spider, Great Green Bush-cricket, Mediterranean Oil Beetle and the Devon Red-legged Robberfly, but of course, by improving and expanding the habitats used by these species, a plethora of wildlife will benefit.

Buglife will be working alongside its project partners to create opportunities for local communities, landowners, parish councils and schools to get involved via volunteer days, habitat management and creation workshops, wildlife gardening and species monitoring. The project is currently in its development phase and is focused on public consultation and species and habitat monitoring – this work will help to secure funding for the next phase of the project.

NHBS conservation volunteering day 

My role as a volunteer is to undertake surveys throughout the flight season of both the Long-horned Bee and its cuckoo between May and July and record the number of individuals seen along this stretch of coast, with a particular focus on known nest aggregation sites and the coastal path between Gara Rock and Mattiscombe Sands. The survey consists of slowly walking along the coastal path, stopping to count Long-horned Bees when I see them. I record the number of males and females, the location/grid reference, and any extra information that may be useful, such as the plants that they are feeding on.

It was wonderful to see so many Long-horned Bees foraging along the cliff top throughout the day. As mentioned above, they tend to favour plants such as Bird’s-foot-trefoil, clovers, Narrow-leaved Everlasting-pea, brambles and Kidney Vetch, and there are sections of the coastal path where these can be found in abundance. Unfortunately, these plentiful patches are in short supply, and Buglife hopes to identify the key areas for habitat enhancement to support the population of Long-horned Bees, which will in turn benefit the Six-banded Nomad Bee.

The highlight of the day was watching one nest aggregation in particular, a site that we have become quite familiar with over the years. It is always a bustling hub of activity and is primarily where the Six-banded Nomad Bee has been recorded in the past. Female Long-horned Bees were repeatedly flitting in and out of the nest entrance holes, with the occasional male patrolling the nest entrances in search of a mate. Sadly, I did not see the Six-banded Nomad Bees this time but was pleased to count a total of 75 Long-horned Bee sightings throughout the day.  

I have been involved in monitoring this site since 2017 and so it was wonderful to have the support of NHBS to spend some time at Prawle Point to contribute to this year’s records. It is vital that monitoring along this stretch of coastline continues, especially as our records of the Six-banded Nomad Bee are so few.

Buglife Q&A with Paul Hetherington

Buglife is the only organisation in Europe devoted to the conservation of all invertebrates. Invertebrates are currently facing an extinction crisis.
Today, thousands of invertebrate species are declining and many are heading towards extinction. Worldwide 150,000 species could be gone by 2050 if we do nothing. We spoke to Paul Hetherington at Buglife about the work they are doing to stop the extinction of invertebrates.

Can you tell us a little bit about the history of Buglife and what you consider to be your main goals?

The conservation movement grew during the 1990s, but there was no organisation specialising in invertebrates. This was brought sharply into focus by the creation of the UK Biodiversity Action Plan in 1994, when no organisation existed to fly the flag for invertebrates – to make sure their conservation needs were being looked after. A Feasibility Committee was established to look at the details of setting up an invertebrate conservation body, and ‘A Statement of Need for a New Organisation’ was produced. Twenty of the leading conservation organisations (including the RSPB and Wildlife Trusts) acknowledged that the conservation movement lacked a major spokesman for invertebrate conservation, and welcomed the establishment of one. The result was the foundation of Buglife in 2000, the only organisation in Europe devoted to the conservation of all invertebrates.

Buglife’s aim is to halt the extinction of invertebrate species and to achieve sustainable populations of invertebrates.

We are working hard to achieve this through:

– Promoting the environmental importance of invertebrates and raising awareness about the challenges to their survival.

– Assisting in the development of legislation and policy that will ensure the conservation of invertebrates.

– Developing and disseminating knowledge about how to conserve invertebrates.

– Encouraging and supporting invertebrate conservation initiatives by other organisations in the UK, Europe and worldwide.

– Undertaking practical conservation projects that will contribute to achieving our aim.

In an ideal world where funding for conservation was limitless, what would be your top priorities for ensuring the survival of invertebrates and rectifying the damage that has been done to their populations and habitats?

Putting connectivity back into the landscape. Invertebrates are suffering from a plethora of issues: habitat loss, pesticides and herbicides, climate change, isolation of habitat. Connecting up the remaining good habitat is the single most important change for invertebrates as they can escape natural or human made disaster where they live and can migrate to avoid extreme climate change. This is the principle behind Buglife’s B-Lines project that has plotted a route for connectivity between the best remaining invertebrate habitats across the UK.

On your website you feature the famous quote by David Attenborough that concludes with the terrifying line: “…if the invertebrates were to disappear, the world’s ecosystems would collapse.” Do you think that in general we still place too much emphasis on saving what is often referred to as the ‘charismatic megafauna’ and do not value the smaller animals and plants that are the backbone and life support of our world?

A look at how money is invested in saving species reveals that larger mammals are by far the biggest beneficiaries at over £60 per species whilst invertebrates the worst funded at under 6 pence per species. A sad reflection on how humans fail to understand that if we don’t look after the small creatures the big ones will disappear too, bottom-up conservation has far more likelihood of long term sustainability. Yes, tigers and similar have cute cuddly eyes but without invertebrates the food chains that they depend on would collapse and with them the megafauna would go too. Too often we take the invertebrates for granted as something that is just there, small and ‘insignificant’ forgetting that in reality they are small but irreplaceable foundations for the whole web of life that supports the megafauna and people too.

2020 has been an extremely challenging year for most individuals and organisations. How has the pandemic affected Buglife and the work that you are doing?

The Covid pandemic has had a massive impact upon all of us and Buglife have had to be extremely careful with project organisation and financial controls, to ensure that vital conservation work has been delivered safely and that our staff resource has been retained in gainful employment. Ways of working have changed with the closure of offices and a shift to home working for all made possible through recent investment in new IT systems. Most engagement activities have shifted from face to face to online platforms as have meetings to influence policy and media. Some of these enforced changes are likely to have a long term beneficial outcome in reducing our organisational carbon footprint and finding new ways of delivering training and engagement that can reach larger audiences. A few of the impacts have meant works being delayed a year such as surveys for specific invertebrates that are only around for short periods. It should also be recognised that new ways of working can place extra burden on staffing resources as meetings flow on without breaks so we have also looked to bring in external supports for staff when needed. The biggest negative impact has been the closure of most project funders to new applications over the pandemic, making it impossible to establish all the new projects hoped for in 2021.


What would you consider to be your greatest success as a charity?

This is a really tough question as over the last 20 years Buglife has achieved  saving many sites for invertebrates from developments, banning extremely harmful chemicals, persuading governments to adopt pollinator strategies, but for sheer scale, B-Lines mapping completed across the entire UK has got to be the number one achievement, as there is now a route map for future interventions to ensure the long term survival of the small things that run the planet.

Finally, for anyone inspired to get involved in invertebrate conservation, how would you recommend that they do this?

Practical experience of conservation work is as important as qualifications, a sound knowledge of a few groups of invertebrates is a great extra to have but equally important is experience of public engagement, volunteer leadership and above all else an ability to multitask.
