The goal of this project is to detect northern muriqui individuals in small and isolated forest fragments surrounding the Caparaó National Park, using drones and thermal cameras, to drive management and conservation strategies. Recent studies on northern muriqui at the CNP have pointed out two female muriquis isolated in the neighbouring of the park (one already managed in partnership with the MIB NGO), and two other muriqui individuals (one female, one male) have died during attempts of moving between forest patches. Along with these activities, this project aims to evaluate the extension of the area used by northern muriqui groups and other primate species, identify potential routes for dispersion of female muriquis, and determine potential areas for restoration inside the park.
