Wembury BioBlitz 2019- Interview with Nicholas Helm

A BioBlitz is an intense period of biological survey of all the living creatures in a specific area, bringing together volunteers, scientists and naturalists to discover as many species as possible in a precise time frame. This year is the 10^th anniversary of the UKs first marine and coastal BioBlitz and it returns to the first location- Wembury Bay. This year’s event is being organised in partnership with the Devon Wildlife Trust, the Marine Biological Association of the UK and the South Devon AONB.

One of the organisers, Nicholas Helm has taken time to speak with us about this year’s event.

The BioBlitz has taken place in different locations across Devon and Cornwall, UK for the last 10 years, what makes this BioBlitz different to other years?

The first BioBlitz we ran in 2009 was at Wembury and was the first public, marine BioBlitz in the UK. Since then we have run one or more events each year for 10 years, several of which have partnered with Devon Wildlife Trust. Returning to Wembury 10 years on allows us to observe what has changed in that time as well as providing a great opportunity to celebrate the milestone. It also coincides with the 25^thanniversary of Wembury Marine Centre, which provides a fantastic backdrop to the event.

Can you tell us about Wembury Bay and what makes it a great location to explore?

Wembury Bay is a unique and special place. Due to its aspect and location, the shore is home to many southern species, not found anywhere else in the UK outside of Cornwall. The Bay incudes a whole host of habitats, from sand and seagrass in the mouth of the Yealm Estuary to the diverse rocky reefs stretching from Wembury Point – where they are exposed at low water – down to deeper, subtidal ledges beyond the Mewstone. These ledges are home to corals and a huge diversity of fish. The area provides nursery areas for sharks and feeding grounds for basking sharks, sea birds and marine mammals. As well as a diverse marine environment, the bay is fringed by fascinating and biologically diverse woodlands and coastal heathlands, home to rare birds, insects, reptiles and mammals, making it perfect for an event of this kind!

What’s your favourite animal you’ve ever found at Wembury Bay?

Personally, my favourite animals in the bay are the giant gobies (Gobius cobitus) which is a large goby, protected under the Wildlife and Countryside Act and not found anywhere in the UK outside of Cornwall. It is common in the upper shore pools of Wembury and is always an exciting find. The other star is the ‘St Pirran’s crab’ – a colourful hermit crab thought to have disappeared from the area in the 1960s but making a return in the last few years and now fairly common. Again, Wembury is the only site in the UK outside of Cornwall where this species has been recorded. I also love finding the stalked jellyfish and colourful nudibranchs that can be found in abundance in pools and under rocks if you know where to look!

This year, the BioBlitz is returning to Wembury after 10 years. How do you think the types of creatures found this year will compare to the first Wembury BioBlitz?

I expect we will observe a lot of changes, in particular there are likely to be a number of new introduced species and several species which have extended their range into the area as a result of climate change. We will also hopefully record the St Pirran’s crab (Clibanarius erythropus) which, in 2009 was not found in the area.

What happens to the data that volunteers, scientists and naturalists will collect at Wembury BioBlitz 2019?

All the data collected will be archived in DASSH (the national data archive for marine and coastal species and habitats) and made publicly available through the National Biodiversity Network Atlas. It will also be taken and held by Devon Local Records Centre and summarised in a final event report, which will be freely available online.

How can readers get involved with the activities available at Wembury BioBlitz 2019?

There are lots of ways to get involved, as a volunteer, species recorder or as a participant in the many activities we have scheduled throughout the event. Visit www.mba.ac.uk/bioblitz for more information.

NHBS Field Sessions: Waterway Surveys for Daubenton’s Bats

NHBS’ staff members are wild about wildlife! To showcase this, we are encouraging our team to write blogs about their experiences with nature.

During the Summer months, Jon Flynn, a member of NHBS’ Wildlife Equipment Team attended a number of Waterway Surveys for Daubenton’s bats (Myotis daubentonii). Read more about his survey experiences below:

“On Monday 6^th July I took part in a Waterway Survey for Daubenton’s bat along a stretch of the River Teign in Devon. The survey is completed twice per year in conjunction with the Bat Conservation Trust and is part of an ongoing data collection programme for bat species around the UK. The lead for this particular survey was John Mitchell who has been surveying this particular length of the Teign, near Teigngrace, for a good number of years. It was my third survey there.

The survey was due to start 40 minutes after sunset, so we met at 9.00pm and made our way along the edge of a maize field to arrive at our first stopping point. This was to be a transect survey which meant walking a length of the river bank and stopping at ten predetermined points to record bat activity at each one. We stood at the river’s edge and immediately noticed that the river level was a lot lower than it was during our last visit a year or so ago. We recorded air temperature and cloud cover and, as we prepared, various species of bats could already be seen zooming around the trees and openings as they commenced another night of nocturnal foraging. The air was very warm, still and humid, and flying insects were everywhere including a host of moths and some less welcome biting species.

As the light faded it was time to start. With bat detectors switched on and earphones in place, we directed a torch beam on the river’s surface and awaited the arrival of the first Daubenton’s.

The Daubenton’s bat is a species which typically occupies riparian woodland. They often roost in trees along the river bank and hunt by skimming low over the surface of the water for insects. They can take prey from the water’s surface using their feet or tail membrane.

As bats skimmed through the torch beam we were able to count them. We counted the number of passes that we observed and for this a clicker counter is always useful! The bats that we heard but did not see were also recorded as additional information. I set my Magenta 5 at 50hz and listened whilst John relied on his trusty and more accomplished Bat Box Duet.

After four minutes on the stopwatch we finished counting, compared counts and wrote down results. At stop number 1 there were certainly bats present, but they were swooping around quite high above the water surface and not showing the typical behaviour of Daubenton’s – John was dubious that they were our target species so we recorded them only as potential sightings.

Using GPS devices and torches we left for Survey Point 2 further down the river bank and repeated the same process as before. At this location there was no denying that these WERE Daubenton’s bats, as the torch beam caught their pale almost white ventral fur, confirming their identity. Our detectors were full of noise too, including the typical intense zap as a bat homed in on prey.

On we progressed with eight more stopping points to go. Occasionally our river bank scrambles took us through thickets of invasive Himalayan balsam (Impatiens glandulifera) and Japanese knotweed (Fallopia japonica)– a sobering reminder of how our countryside is changing. The night remained still and warm and it almost felt like we were in a different country.

After eight more stops my watch said 11:20pm. It was good to see that bats were in profusion that night, as John stated ‘It was one of the best ever totals, with one stopping point recording over 50 passes!‘.

Two weeks later and we repeated the process. But this second night felt noticeably cooler and there were fewer insects on the wing. Nevertheless bats were still out and about in reasonable numbers and an average score was calculated between the two Waterway surveys. Overall there were encouraging signs that the Daubenton’s bat continues to do well along this particular stretch of the Teign.”

Conservation Volunteering at Ambios Farm and Wildlife Fayre

At NHBS, all members of staff have the opportunity to partake in conservation volunteering days as part of the company’s philanthropic initiative to carry out nature conservation locally. As part of this initiative, I recently chose to volunteer at an event for a cause that is close to my heart nearby in Totnes.

On Friday 8th June, I volunteered at a Farm and Wildlife Fayre run by Ambios, an organisation that provides education and volunteering opportunities in nature conservation in the UK and abroad. Set in the beautiful Sharpham Estate, with the river Dart and rolling hills surrounding the farm, it was the perfect setting to engage others in nature conservation. This place is special to me, as this is where my initial nature conservation training began before I joined NHBS in 2017. Below is a video of the Wildlife Fayre filmed by Ross Gill of Fresh Ground Films.

At the Wildlife Fayre I worked alongside conservation volunteers, knowledgeable experts in the field and the charity, United Response, who provide a range of support services for individuals with physical and learning difficulties. The aim of the event was to get a wider audience of people involved in nature conservation by allowing them to take part in accessible activities that help individuals to get up-close and personal with local wildlife. More than 200 children and young adults from special needs schools and colleges attended, in addition to young families from the local area.

Engaging and educational activities drew in crowds, including bug hunts, bird box making, forest school sessions, green woodworking and plant identification. The air was filled with excitement as children and adults alike rushed around with their newly carved spatulas and bird boxes. Footsteps hurried as groups rushed between activities with freshly picked produce from the farm in their hands.

The farm office was transformed into a wildlife information hub, which hosted an array of interesting finds. Through microscopes you were transported into another world where you could view bumblebees and Garden Chafer Beetles at close range.

Tanks held Palmate Newts hiding amongst curtains of pond weed and field guides lay next to plaster-cast footprints of creatures who had visited the farm. In one corner, a table was covered with flora found locally for anyone wishing to test their plant identification skills. In another, an array of uncommonly seen finds were lined up including the skulls of animals and tightly woven dormouse nests.

Something that really drew me in were the screens in the wildlife information hub which displayed stories of the wild residents of Sharpham, including nest box inhabitants and various small mammals. You could watch a timeline of Blue Tits building their nest and sitting on eggs. Later you saw the chicks being fed, strengthening their wings and finally fledging!

My responsibilities whilst volunteering at the event revolved around providing support and an extra pair of hands. I helped groups to move between activities and demonstrated how to use tools and equipment such as nets and pooters. At NHBS I work as a Wildlife Equipment Specialist, so it was great to be able to show others first-hand how to use the equipment that we have access to every day. It was lovely to see how excited the children got about using the equipment to get closer to nature.

The Farm and Wildlife Fayre was a fantastic success! The event proved to be a brilliant way of captivating young minds and introducing them to the natural world. By partaking in accessible activities, each person felt confident enough to try something new and learnt a great deal along the way.

Ambios Director and Farm Manager said,

“Our farm and wildlife fayre was a huge success – we are delighted! We had nearly 200 people over the day, from all walks of life experiencing what we do at lower sharpham farm, and getting up close and personal with wildlife as well as getting to know our farm animals. Our farming practice aims to prioritise wildlife, and we are delighted to share our work and our story with a wide audience. Our next event will be a barn dance in the late summer, so watch this space!”

It was great to be involved and I love to think that if this event has inspired just one person to appreciate and protect nature a little further, then it was all worth it!

Stay tuned for more volunteer event posts from my colleagues at NHBS as they embark on their own conservation volunteering days.
