In an effort to keep black bears safe, Yosemite National Park has introduced Keep Bears Wild, a tracking system anyone can access. The program will relay the bears’ movements through the park’s 1,100 square miles via GPS collars. Park rangers are hoping the tracker will help motorists exercise caution driving in areas where bears have been hit, and sadly often killed, by cars. Last year alone, more than 5% of Yosemite National Park’s black bear population was struck by visiting drivers. The information gathered from the GPS is also intended to protect humans, by helping ensure the animals stay away from campgrounds and parking lots. Already, the Keep Bear Wild program is revealing data that surprised even the rangers, such as the bears mate in May, a full month before they were thought to.
