NSW koala baseline survey 2025 - occupancy and abundance models

Brief description

The statewide koala baseline survey is a standalone snapshot of the occurrence, distribution and relative abundance of koalas in NSW in 2025. The baseline survey covers the plausible range of koalas in NSW and over 1,000 sites were sampled across land tenures using heat-sensing drones and passive acoustic recorders. The survey also provides a baseline population estimate from which to evaluate koala population trends over time. \r\n\r\nThis dataset comprises state-wide occupancy and abundance models derived from acoustic and drone data and environmental covariates as described in the NSW koala baseline technical report, 2025
