Counting Squirrels in Indian Forests

superadmin Announcements, Articles Leave a Comment

Although the ecology of squirrels has been extensively studied, most past work is characterized by the failure to account for detection and heavy reliance on indices rather than directly measuring abundance. This has involved acoustic and visual surveys, sign surveys (tracks, middens and dreys) and capture-recapture sampling (trapping rates) methods are adopted to estimate squirrel abundance. Such field studies assume the detection probability of the species to be equal in all sites, leading to incorrect estimates of true abundance.

superadmin Ask CI Leave a Comment

Answer from Shekar Dattatri of Conservation India:

Radio-collaring of animals is a tried and tested method of studying free-ranging wild animals that has been in practice for several decades. It is primarily used for tracking the movement and activity patterns of the tagged animal, with the signals being sent to a handheld device or to a computer via a satellite. It is often the only method that is available for studying the movement and activity patterns of a secretive species … Read More
