Leopards have lost a third of their historical
range, and their current CITES status is ‘Near Threatened’ even though they have
the largest natural distribution among felids. In this paper the authors
describe the pros and cons of normal camera trapping versus baited camera trapping
in getting accurate data on leopard populations
unbaited camera-trapping has the disadvantage
of low capture rates which in turn affects the accuracy of the resultant density
calculations. Another disadvantage is that dependent cubs are underrepresented
in the data skewing demographic structure.
In their research the scientists found that baited
camera-trapping significantly increased leopard capture rates, as well as
recording dependent cubs. To boot it was also cost effective. It has the
potential to accurately survey unmonitored populations; including where their
density is too low to determine accurately via other means.
