Curriculum Content Standards: Science

Site Description:

The Swan River Oxbow Preserve derives its name from a long, curving oxbow in which the Swan River used to flow. The variety of wetland communities create a haven for birds and harbor five rare plant populations and two rare lichens. Spruce forest predominates along the southern boundary. A complex of sedge fen and birch carr communities lie adjacent to the spring system. To the west, cottonwood forest dominates the area around the aquatic oxbow.

The water howellia is federally listed as threatened. On the preserve, howellia grows in the marshy areas next to the oxbow. An annual plant with white flowers, howellia requires a delicate balance of conditions for its survival. The plant must be submerged in water to grow and reproduce. Its seed won’t germinate under water, so howellia must grow in ponds that are flooded in spring, and dry by late summer or fall. If conditions are too wet, the seeds will not germinate. In drought conditions, the plant won’t grow.

Trails and Terrain:

All trails are signed. The trail is 1.5 miles to the overlook at the Oxbow, one-way. The terrain is flat.

Wildlife Present:

Grizzly bears use the preserve as a corridor between mountain ranges and feed on native fruits, such as huckleberries and herbaceous plants in the area. Bald eagles and osprey roost in the trees and feed along the river. Elk, moose and white-tailed deer may also be found on the preserve.Swan River Oxbow Preserve Photo
