In both years, we sampled the
exact same locations inside and outside the Chitwan National Park [both
regions dominated by Sal (Shorea robusta) forest] in four successive blocks,
each sampled for ∼20 d at ∼20 locations. In 2011, we also sampled one additional
location in each block; thus, we placed traps in a total of 76 locations
in 2010 and 79 locations in 2011 (one trap was stolen in 2011) (Table S1).
