Development of a bird habitat resource classification scheme based on vegetation structure analysis

Abstract

In order to design a conservation strategy for birds inhabiting the Great Western Woodlands (GWW) in southwestern Australia, we adopted a new approach for classifying birds into functional groups (BHFGs) based on an analysis of vegetation structure-related habitat resources (VHR). On the basis of hierarchical cluster analysis of the VHR variables we selected here, we selected a model that incorporated nine-BHFGs. This yielded a classification system that, due to our different input sources, is distinct from an existing foraging guild-based system. In conjunction with GIS technique, this new classification system has potential for effectively predicting and mapping landscape-scale habitat distribution.
