Methods for determining feral goat abundance in rugged terrain

Estimation of the abundance and density of vertebrate pests is difficult but critical for management. A study in the rugged terrain of central eastern New South Wales used and compared several techniques to estimate the abundance of feral goats (Capra hircus). These methods include Aerial double-counts conducted with helicopters; Aerial videography; Ground-based area counts and area double-counts; Minimum number known to be alive (MNA) estimates calculated from ground counts taken at fixed points; Mark-recapture estimates resulting from musters; Mark-resight estimates gained from extensive field observations.
