The map displays detection data on koalas by site and date of survey. Detection has been carried out via low level surveillance using drones and machine learning (see Corcoran et al, 2019, Scientific Reports 9:3208 for details). The number of detections is also displayed. Note that the number of detections is not the equivalent of abundance. All monitoring methods have some associated error and appropriate statistical estimation methods should be applied to the detection data to estimate abundance.
