Wood Bison (IMAGE) Max Planck Institute of Geoanthropology Caption The wood bison (Bison bison spp. athabascae) of the Ust'-Buotama Bison Park, central Sakha Republic, Russia. In 2006, 35 wood bison were brought from Canada. These megaherbivores adapted to local environment and increased their population. The 100-ha enclosure, where animals live, serves as a study site for ecologists and zoologists and provides an opportunity to trace changes in vegetation associated with herbivore pressure.
