The model predicted there were 24,583km2 classified as takin suitable habitat(Figure 2), equaling 18.97% of CDR. The number of patches larger than seasonal home-range of takin (5km2; Guan et al.,2015) was 122, covering 23,710km2 or 96.45% of the UDR. The total habitat size in patch B was less than 7km2, and the largest contiguous habitat within patch B (2.8km2) is much less than takin annual home range (15km2, Guan et al.,2015). There was no suitable habitat in patch C.

Takin distribution update By delineating the grids corners on the edges (Figure 3), we created a range based on conservative predictions and known environment limits. Then, after overlapping the range with polygon published in the IUCN Red List, we derived the updated map of takin distribution (Figure 4). The size of UDR of takin in Sichuan was 79,449km2, 61.31% of the total area of the CDR.
