Roost Features

An account of how Potential Roost Features (PRF) form, why they form, where they form, why they form where they form, and approximately how long they can be predicted to last;

Trees

An account of how bat species native to the British Isles use trees

Dichotomous Key

A dichotomous key to potential bat-roosts in trees for use in the formation of a hypothesis used to guide further survey effort, and also an interpretive tool to give a hypothesis of what might have been present, where conclusive evidence has eluded survey.

Bat Tree Habitat Key is a free web-hosted publication in three parts that was written by AEcol Principal Ecologist, Henry Andrews.

Bat Tree Habitat Key comprises:

  1. An account of how Potential Roost Features (PRF) form, why they form, where they form, why they form where they form, and approximately how long they can be predicted to last;
  2. An account of how bat species native to the British Isles use trees; and
  3. A dichotomous key to potential bat-roosts in trees for use in the formation of a hypothesis used to guide further survey effort, and also an interpretive tool to give a hypothesis of what might have been present, where conclusive evidence has eluded survey.

In order to complete the project a database framework has been defined and an ‘open-access’ database created. This data will be¬†collated and analysed¬†annually in order to produce a report. The first report was published in 2016 and is provided under the relevant tab above. The results and conclusions will then be used to revise Bat Tree Habitat Key.
