West Sussex Bat Trapping

Over the summer, the Inspired Ecology team travelled down to West Sussex to assist AECOM with bat trapping surveys. Between July and September, surveys were conducted at three different sites, with one at each site during each month.

Harp traps, so called because they look remarkably similar to a harp when set up, were the most successful at catching bats, though mist nets also managed to catch a small number of bats. Once caught, the team identified the species, took wing measurements and weighed the bats, before releasing them again.

Numerous different species were recorded by the team, including common pipistrelle, soprano pipistrelle, brown long-eared bat, Natterer’s bat, whiskered bat and noctule. The most exciting catch of the summer was reserved for Bechstein’s bat however. This species is one of the UK’s rarest bats and is found in just a small number of places in the south of England and Wales, making it a very important and special find for the project and for UK bat conservation!

’tis the season…

…for bat hibernation checks!

The bat activity survey season may be finished for the year, but the team at Scarborough Nixon Associates Ltd will be carrying out hibernation surveys for bats throughout December, January and February.

Sites to be surveyed include Tattershall Carrs, a Woodland Trust site, recently seen on BBC Countryfile! Over the last couple of years, Ian Nixon has led a project to transform some of the Stanton shelters and remaining wartime structures within the woodland to provide winter roosting features for bats. The features include bat boxes and the specially designed Lincolnshire Bat Brick. These features have now been in place for 18 months, and hibernation surveys in winter 2015/2016 showed that the structures were being used by small numbers of bats, including brown long-eared and Natterer’s. This winter, further hibernation surveys will take place to monitor the population of hibernating bats within the woodland, and all data will be submitted to Bat Conservation Trust as part of the National Bat Monitoring Programme.

Water vole update

In January 2016, a class licence (CL31) was introduced to “intentionally damage or destroy water vole burrows and to disturb by displacing water voles occupying burrows before carrying out lawful development works”. Scarborough Nixon Associates Ltd are pleased to announce that they have completed the licensing process with Natural England and are registered to use the class licence to carry out water vole displacement work.

Scarborough Nixon Associates Ltd offer water vole surveys both as part of our general walkover surveys and ecological assessments and also as focused species specific surveys, for a range of clients including private developers, internal drainage boards and The Environment Agency. All our survey work and water vole displacement work is undertaken by experienced ecologists in accordance with the latest industry guidelines, published in The Water Vole Mitigation Handbook (Dean et al. 2016).
