Directions This site is located in the Fisher River watershed in northwest Montana. From Libby, travel east on State Route 37 for 14 miles. Turn south on the Fisher River Road and travel for about 7 miles to Forest Road 534. Travel west on this road for approximately 1.5 miles. Description This site is a small (2.5-acre) wetland with some peat development. Beaver activity has created several small ponds and raised water tables throughout the wetland. The majority of the site occurs on a slightly elevated flat with relatively little microtopography. Soils have high organic content. An open canopy Betula occidentalis (Water Birch) shrubland with a near-continuous Carex utriculata (Beaked Sedge) ground layer forms the dominant vegetation of this area. Other common species include Rhamnus alnifolia (Alderleaf Buckthorn), Cornus sericea (Red-Osier Dogwood), Salix bebbiana (Bebb Willow), Bromus ciliatus (Fringed Brome), Carex cusickii (Cusick's Sedge), and Viola sp. (Violet). Scattered sapling-size Picea engelmannii (Engelmann Spruce) and Pseudotsuga menziesii (Douglas-fir) are also present. Wetter areas support small patches of Typha latifolia (Broadleaf Cattail) and Petasites frigidus var. sagittatus (Arrowleaf Colt's-foot). A mature Picea engelmannii / Equisetum arvense (Engelmann Spruce / Field Horsetail) community occupies the Doe Creek floodplain upstream and downstream of the shrubland. This community supports numerous mesic forbs and has shrubby inclusions of Alnus incana (Mountain Alder). The uplands are second-growth Larix occidentalis (Western Larch) - Pseudotsuga menziesii forest. Key Environmental Factors These wetlands are influenced by past beaver activity and high water tables. 13
