The fifty four species of mammals recorded at the H.J. Andrews Forest include black bear, flying squirrel, spotted skunk, and red tree voles. New techniques such as DNA metabarcoding allow researchers to detect species that may elude more traditional methods of sampling. DNA metabarcoding of animal scat allows researchers to use animals to sample the other animals in the forest. For example, researchers can sample fox scat and detect DNA of the species of mammals in the fox's diet. This allows researchers to detect animals like red tree voles and white-footed voles.
