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.

distribution range and environment limits.
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.
