Field validation of a Species Distribution Model for the central Evolutionarily Significant Unit of the brush-tailed rock-wallaby through aerial surveys

Abstract

<p>Understanding the distribution of threatened species is key to informing their conservation. Species Distribution Modelling (SDM) is used for a wide range of conservation purposes, and can identify areas of suitable habitat and guide targeted field surveys to help refine our knowledge of a species' current geographic range. The brush-tailed rock-wallaby (Petrogale penicillata) is listed as endangered in NSW, with the central Evolutionary Significant Unit (cESU) of this species being of particular conservation concern. This species inhabits rocky refugia in rugged and often remote terrain, making it particularly difficult to survey. As a result, there is limited understanding of its current distribution.</p>
