New habitat monitoring tools find hope for tigers
here’s still enough forest left — if protected wisely — to meet the goal of doubling the number of wild tigers (Panthera tigris) by 2022, says an international research team.
That ambitious target, set by a summit of 13 tiger-range nations in 2010, aims to reverse the species’ alarming plunge toward extinction. Forest loss, poaching and dwindling prey have driven tiger numbers below 3,500 individuals.
The existing forest habitat could sustain the doubling if, for instance, safe-travel corridors connect forest patches, according to researchers monitoring forest loss with free, anybody-can-use-’em Web tools. Previously, habitat monitoring was piecemeal, in part because satellite imagery could be expensive and required special expertise, says Anup Joshi of the University of Minnesota in St. Paul. But Google Earth Engine and Global Forest Watch provide faster, easier, more consistent ways to keep an eye out for habitat losses as small as 30 meters by 30 meters (the space revealed in a pixel).
