Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Arrowleaf Ragwort - Seep Monkeyflower Wet Meadow
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This wet forb-dominated herbaceous type occurs in Wyoming and Oregon in the mountains at upper montane and subalpine elevations. It is commonly associated with moderately steep to steep mid to low slopes usually near seeps, and wet toeslopes. Soils are silty clay loam to sandy and are saturated throughout the growing season. This is a wet herb-rich association. It is usually dominated by forbs; Senecio triangularis is the most consistently present species across all document sites. Common co-associates include Mimulus lewisii, Mimulus guttatus, Mitella pentandra, Platanthera dilatata, and Epilobium spp. Graminoids are also often present and can have individually high cover but are never as abundant as all forb cover combined. Graminoids include Agrostis exarata, Carex paysonis, Deschampsia cespitosa, and Juncus mertensianus.

Environmental Description: This wet forb-dominated herbaceous type occurs in the mountains at fairly high elevations. It is commonly associated with moderately steep to steep mid to low slopes usually near seeps, and wet toeslopes. Soils are silty clay loam to sandy and are saturated and non-stagnant throughout the growing season.
Geographic Range: This association is known from Yellowstone and Grand Teton national parks and from Grey''s River watershed in west-central Wyoming. It also occurs in Oregon.
