Use of a Geographical Information System to evaluate Capercaillie (Tetrao urogallus) Habitat within the Glen Affric Caledonian Forest Reserve

Male capercaillie

In 2000, Colin Stewart, a Masters student at Edinburgh University, carried out research on the habitat of capercaillie in Glen Affric. Here is the abstract of Colin's work, from his thesis document.

Abstract

The capercaillie, Tetrao urogallus, is rapidly diminishing in numbers throughout its range within Scotland. Conservation of this species is dependent upon identifying core home ranges and managing these areas sympathetically. Thus studies identifying key habitat requirements are vital.

A habitat suitability model has been developed within a Geographical Information System to evaluate the extent of capercaillie habitat within the Glen Affric Caledonian Forest Reserve. The model is composed of two variables - habitat structure and security - values of which are combined in a simple relationship to produce a categorical assessment of habitat quality. This model indicates that optimal capercaillie habitat within Glen Affric is highly fragmented and restricted in extent. This poses serious concerns for the long-term survival of the capercaillie within this area.
