BSG Ecology’s Guy Miller, one of our licenced bat ecologists, supported by Adam Long (Access Techniques Ltd), an industrial rope access specialist, has recently conducted aerial surveys of the Grand Bridge at Blenheim Park, Oxfordshire. The aim has been to identify and inspect features of the bridge that have the potential to support roosting bats and nesting birds. The resulting information will be used to inform the approach taken to forthcoming repair work, ensuring that it is legally compliant and that opportunities for birds and bats are retained within the structure following renovation.
We have recently captured and tracked bats to inform mitigation for impacts on woodland in north-eastern England. This short article outlines why these methods were necessary and how the results will benefit our client.
The footage below shows lesser horseshoe bats Rhinolophus hipposideros emerging from a stone shed that supports a maternity roost. It was captured in early August 2019 by BSG Ecology’s Guy Miller and Hannah Daniels, using one of BSG Ecology’s FLIR T650sc thermal imaging cameras. The location is near Abergavenny, Monmouthshire.
Environmental DNA (eDNA) survey can provide a rapid and cost effective means of determining the presence or likely absence of great crested newts. This short article gives some insight into the benefits and limitations of the technique.
At BSG, we regularly use thermal imaging technology to supplement more standard methods of data collection, and answer questions that need to be addressed in Ecological Impact Assessment and Habitats Regulations Assessment work. In some circumstances, it can provide a more robust evidence base for our clients’ projects. The value of thermal imaging in wildlife recording has been recognised by NHBS, the largest supplier of wildlife, ecology and conservation books and equipment in Europe, who have used footage provided by BSG in their latest article entitled ‘NHBS Guide to Night Vision and Thermal Optics.’ Most of this footage has been collected in the course of commercial work.
