From: Land-use change is associated with multi-century loss of elephant ecosystems in Asia
Loss of suitable habitat from 850 to 2015. Masked areas (Hainan Island and part of Pakistan) have been excluded from analyses, and for visual clarity all of China is not shown. Shaded area (Borneo) is outside the currently known historic range. (a) Habitat suitability predicted on the basis of elevation and the Land-use Harmonization (LUH) variables from the year 2000. (b) Binarized map where 1 (yellow) indicates “suitable” areas with values above 0.284 (threshold of ‘maximum training sensitivity plus specificity’) and 0 (blue) indicates “unsuitable” areas. (c) Changes in the extent and spatial configuration of suitable habitat, where each curve corresponds to the given threshold value. Total Suitable Area is the sum of all suitable habitat across the range. Area-Weighted Mean Patch Size is the weighted average of patch sizes. The Largest Patch Index is the percentage of total area occupied by the largest patch. The Landscape Contagion Index can be thought of as a measure of homogeneity, with higher probabilities representing fewer, more clumped patches. See Table S4 for complete list of fragmentation measures.
