Research & Development - Bats & Trees training

AEcol Principal Ecologist Henry Andrews is a specialist in woodland bat ecology and an experienced trainer who has helped many organisations fill in gaps in their knowledge.

AEcol Training - We won't teach you the methods for searching, we'll teach you the methods for finding

As the author of Bat Tree Habitat Key Henry has a comprehensive knowledge of tree-roosting ecology and can teach you how to identify all the Potential Roost Features (PRF) present in and on trees.

He can explain how each PRF forms, and teach you where they form on the tree and how to search for them. He can show you how the individual bat species use each PRF. He can show you how to survey for tree-roosts in woodlands using field-craft that you probably already possess, but just need to put into context. He can demonstrate practical methods for PRF mapping, assessment and repeat survey. He can show you not only how to find bats in PRF using torches and endoscopes, but which field-signs are reliable indicators of past presence when there are no bats present on the day you look.

So, whether you're a forest manager, woodsman or woman, an arborist or an ecological consultant, Henry can provide you with sufficient knowledge to be confident of finding bats in trees for yourself. 

At the moment, we offer a three-day course in Somerset that focusses in depth on all aspects of tree-roosting ecology and survey. Each day comprises class-room talks and field-based exercises visiting and inspecting a wide variety of roosts used by a wide variety of bat-species. You'll be equipped with lots of helpful reference material (all with practical application in mind), and closely assessed so we can test what you have learned and we can fill in any gaps. The course has a maximum of 12 participants and two full-time instructors.

Remaining 2015 courses will be running from 10th to 12th November and 8th to 10th December.
