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 6th 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.”

If you like the idea of taking part in Waterway Surveys (or other kinds of bat surveys) then contact the Bat Conservation Trust or have a look at their website here. It’s great fun and you can put your bat detector to important use!
Lars: Let us say that in my case only 15 of these 18 years were spent on the new handbook. I was involved in doing the second edition of the 
Hadoram: At least as I see it, BWP was made some 20-30 years ago when it was still possible to squeeze information into one project – on distribution, population estimates, atlas, ecology, seasonal biology, behaviour, voice, and so on, as well as identification and variation (but with generally only very basic illustrations, paintings) – and to be satisfied with it!
Lars: To assemble the many photographs (there are well over 4000 photographs together in the two passerine volumes) and to achieve full coverage of male and female, young and adult, sometimes also in both spring and autumn, plus examples of distinct subspecies, was of course a major challenge. Hadoram was in charge of this and did a great job, and we got good support from our publisher setting up a home page for the project where photographers could see what we still needed photographs of. Thanks to the prolonged production, many gaps (if not all!) were filled during our course.
Hadoram: Lars described in his answers very well, the combined efforts with the museum collections work and building the photographic collections and selections for the project.
Lars: Digital photography and the existence of internet and websites for documentation and discussion of bird images are the main changes compared to when I started as a birdwatcher. This has speeded up the exchange of news and knowledge in a remarkable way. True, field-guides and birding journals keep offering better and better advice on tricky identification problems, and optical aids have developed to a much higher standard than say 50 years ago. But the new cameras with stabilised lenses and autofocus have meant a lot and have enabled so-called ‘ordinary’ birders to take excellent photographs. This has broadened the cadre of photographers and multiplied the production of top class images of previously rarely photographed species. Which of course made 
Lars: I have planned for many years now to revise my 
My books are not field guides at all. A field guide gives you a list of plant names, with pictures and descriptions, sometimes with a brief introduction. My books are all introduction: to field botany in general, to plant families and to grasses (maybe sedges and rushes next year . . .). A beginner armed only with a field guide has either to work their way from scratch through complicated keys, or to play snap: plant in one hand, book in the other; turn the pages until you find a picture that matches – ‘snap!’ By contrast, my books lead you into plant identification by logical routes, showing you where to look and what to look for. Their aim is to show you how to do ID for yourself.
If you possibly can, go on a workshop for a day, a weekend or even a whole week. Having a real live person giving enthusiastic teaching, someone to answer all your questions and fresh plants to study is the best thing you can do. Look for a local botany or natural history group you can join, and go on their field meetings. When you get even a little more serious about your study, join Plantlife and/or the Botanical Society of Britain & Ireland. Identiplant is a very good online course but it is not really suitable for absolute beginners. Be a bit careful with apps and websites: some are incredibly complex, some seem to be aimed at five-year-olds, others are just inaccurate and misleading. The best ID websites I am aware of are run by the 
The main threat is not people picking a few to study, or even simply to enjoy at home. Climate change is, of course, a threat in one sense, but I believe we shouldn’t necessarily dread the rise of ‘aliens’ from warmer climates which are now able to establish themselves here. Every plant in Britain was once an alien, after the last Ice Age ended, and I would rather learn to live with change than blindly try to turn the clock back. There may be a few exceptions like Japanese Knotweed, but their evils are often exaggerated and some natives like bracken can be equally invasive. The real problem we face is habitat loss: to house-building and industry, land drainage, vast monocultural fields without headlands, destruction of ancient forests and so on. And this is an area where watchfulness and action really can make a difference.

The unique features of churchyards mean that they offer a valuable niche for many species. Enclosed churchyard in particular provide a time-capsule and a window into the components of an ancient British landscape. Well known botanist, mycologist and broadcaster Stefan Buczacki has written 
Managing a cemetery in a way that keeps everyone happy seems an impossible job. Last August I was photographing a meadow that had sprung up at a cemetery, when another photographer mentioned how disgusting it was. I was slightly bemused until the man explained he was a town councillor and was disgusted that the cemetery was unmaintained – “an insult to the dead” was how he described it – I thought it looked fantastic! whatever your opinion, how can we achieve common-ground between such diametrically opposed views?
All the significant flora and fauna of churchyards their own chapters or sections; from fungi, lichen and plants, to birds, reptiles, amphibians and mammals? Which class, order or even species do you think has the closest association with churchyards and therefore the most to gain or lose from churchyard’s future conservation status?
With church attendance declining and the future of churchyard maintenance an increasingly secular concern; could you give a brief first-steps outline as to how an individual or a group might set about conserving and even improving the natural history of their local churchyard?
If someone, or a group become custodians of a churchyard what five key actions or augmentations would you most recommend and what two actions would you recommend against?
