NSW Koala Baseline Likelihood Map 2016

The map presents the distribution of the likelihood of koala occurrence across NSW based on publicly available data held in the Atlas of NSW Wildlife ( The proportion (’p’ column) of koalas (‘Koala’ column) recorded relative to a suite of arboreal mammals is presented in a 10 kilometre grid across NSW. A separate 5 kilometre grid is also available for Koala Management Area (KMA) 1 – North Coast. A measure of the confidence (‘Conf’ column) in the likelihood estimate is also presented. In KMA 1 Atlas of NSW Wildlife (Bionet) record data has been supplemented with data from koala spot assessment (SAT) survey along with “rapid SAT” method undertaken where major data deficiencies remained. SAT surveys observation efforts and resulting koala records were used in the same manner as arboreal mammal records. This map can be used to inform the likely occurrence of koalas and informing decisions on mitigation of activities such as native forestry.
