Badru Mugerwa is part of an international effort to monitor changes in vegetation and animal composition from climate change. His piece of the puzzle is in Bwindi Impenetrable National Park in Uganda, where he sets dozens of camera traps designed to record the movements and habits of animals, which range from agile felines to stolid primates and from tiny deer to giant elephants. It’s a job that connects Mugerwa not only to Bwindi’s animals, and local biodiversity concerns, but also to the global issue of climate change.
