Indeed, populations of T. plicata in Khao Chong Phran
have declined by 12.5% from 1999 to 2005 (Hillman, 2006) presumably
due to pesticide use in the area (S. Bumrungsri personal
observations). Leelapaibul et al. (2005) also report guano mining
from roosting caves of T. plicata, which in general is known to affect
bat populations (Csorba et al., 2008). Across Asia these bats are
widely hunted or their roosting caves are converted into quarries
(Clements et al., 2006; Csorba et al., 2008). Hunting pressure and
habitat loss in the Philippines has led to almost complete eradication
of the once abundant Wrinkle-Lipped Bat (Csorba et al., 2008).
