OH Ranch Heritage Rangeland contributes to protection of native grassland characteristics and celebrates the significant ranching history of the area. The designation of the site is a result of cooperation between several government agencies and OH Ranch. The site contains grassland, aspen-dominated forests and willow shrub lands. In montane areas, there are lodgepole pine and white spruce-dominated forests. Wildlife species include wolves, cougars, coyotes, grizzly bears, black bears, moose, mule deer, elk and white-tailed deer. Grouse, hawks, eagles, falcons, owls and waterfowl have also been observed in the area.
