This past summer, PhD candidate Ganesh Marin was hard at work trapping and collaring black bears on the US-Mexico border. His aim is to track the bears' movements to understand how development along the border affects wildlife movement and population connectivity.  


So far, the team trapped and released 4 bears and will be tracking their movements for the next 2.5 years. Geronimo, a male, cinnamon-colored black bear, was seen in wildlife cameras in the company of a female bear. Bears are solitary animals, but a mating pair stays together for several days during summer courtship and mating.

Studies that track animal movements are instrumental for identifying important wildlife corridors that require protection, or showing when populations have been cut off, indicating a need for management intervention. Marin will continue to track this region’s bears through 2025. Stay tuned for updates!
