 Slow lorises are threatened by deforestation and the wildlife trade , which includes the exotic pet trade , traditional medicine , and bushmeat . Other threats includes road construction , selective logging , and slash and burn agriculture . Habitat fragmentation obstructs biological dispersal for these species that rely on vines and lianas to move from tree to tree . Consequently , slow lorises are found dead on power lines or are victims of roadkill in areas where roads cut between forest patches .
