Evaluation of methods for ground survey of feral pigs and their sign

Abstract

Methods for surveying the extent of feral pig rooting, feral pig dung and feral pigs counts were investigated in Namadgi National Park, Australia. The repeatability, precision and accuracy of the methods were examined over twelve months. Repeatable measures od pig rooting and counts of dung pellets were obtained. Rooting was a more accurate indicator of past feral pig presence than dung and counts of feral pigs. The results and their implications for surveying populations of feral pig are discussed.
