Discover ABMI Data & tools
Estimating the density of animal populations over time is an important goal of wildlife monitoring programs like the ABMI. However, estimating density of unmarked populations is a challenging task. Based on a quadrat sampling approach, the Time in Front of Camera (TIFC) method calculates how long individual animals spend in the remote camera field of view based on the images collected.
