Curriculum Content Standards: Science

Site Description:

The Owen Sowerwine Natural Area encompasses 442 acres of land, wetland and water in the braided section of the Flathead and Stillwater rivers within the 100-year floodplain. The most striking feature of the area is the dense forest and brush vegetation that provides shelter and browse for numerous wildlife species. In addition to wildlife, the aquatic habitat of OSNA provides excellent foraging and cover habitat for significant numbers of migratory and resident fish. Much of the area is not easily accessible: islands can only be reached by water, and a portion of Leisure Island is behind a barrier of private land. The remaining roughly 70 acres lie on the mainland, along the west shore of the Stillwater, and can be reached by roads that turn east off of Willow Glen Drive. On this mainland portion, a series of game trails have been cleared and marked by the Flathead Audubon Society, which provide opportunity for quiet recreation and nature education.

Trails and Terrain:

All trails are signed. There is a large map on the kiosk, located at the Treasure Lane entrance, and a small version of the map on trifold brochures available at the kiosk.

(1) Mainland Trail (from Treasure Lane to SW entrance): Over half a mile; a narrow, rough trail, with moderately steep to quite steep parts, with some footbridges over wet areas. The initial 600 feet is ADA accessible, with a viewing area at the end of the trail: in one direction, a viewing area overlooks water and into a stand of cottonwoods on the other side; in the other direction, it looks across a meadow.

(2) Green Ridge Trail (from Green Ridge to intersection with Mainland Trail): about 800 feet; narrow, rough trail, with moderately steep parts.

(3) Green Ridge By-pass Trail: about 600 feet; narrow, rough, with some moderately steep parts; some footbridges over wet areas.

Wildlife Present:

More than 100 species of birds have been recorded at Owen Sowerwine and are detailed on the bird list on the Owen Sowerwine Natural Area Phototrifold brochure available at the kiosk. White-tailed deer, mountain cottontail, beaver, muskrat, red fox, coyote, river otter, striped skunk, mink and other weasels frequently visit. Black bear and moose occasionally visit. Amphibian and reptile species present include western toad, painted turtle, two species of garter snake and rubber boa. A variety of fish species, including the native species westslope cutthroat and bull trout, are present in the river sections.
