Bats – Surveying in Trees and Woodland

With the month of May comes the warm springtime weather, an influx of moths, butterflies and other invertebrates taking flight and – of course – bats taking full advantage of this foraging opportunity after the long winter spent hibernating. For the life of an ecologist, this means one thing: it is bat survey season.

It is only right then, that with this commencement of the survey season, the industry survey guidelines are updated. The British Standard has published a draft version of guidelines for Surveying for Bats in Trees and Woodland BS 8596 which is due for final release in September this year.

This British Standard gives guidance on surveying bats in individual trees, groups of trees and woodland. The aim of which is to bring together all relevant information – covering scoping, roost and activity surveys and record keeping – and is designed to be used by both specialist bat surveyors and non-specialist woodland managers alike. This allows those non-specialists to attain the necessary understanding of the surveys and checks that they can do themselves, while identifying the occasions when the services of a bat specialist might be required.

Even with the support that these guidelines provide, surveying for bats can take time and it is important to consider the constraints these protected species may have on a development at the early stages of the pre-planning process.

At Greengage our team comprises competent bat surveyors including Morgan Taylor who holds a Class 1 Natural England Bat Survey Licence to carry out all necessary roost and activity surveys, as well as a skilled arboriculturalist Tom Luck who is a Technician Member of the Arboricultural Association. The profiles of our staff can be found here.
