CEGL000285 Abies grandis / Trautvetteria caroliniensis Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Grand Fir / Carolina Tassel-rue Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association is found at moderate elevations in the northeastern section of the Blue Mountains ecoregion of Oregon and in Washington. Geomorphic surfaces are floodplains in moderate- to high-gradient, narrow to wide, V- and trough-shaped valleys with gentle to steep sideslopes. Soils are mineral, although an organic or organic-rich surface horizon is often present. Coarse fragments are shallow in the horizon, and the water table is high during the growing season. Adjacent Rosgen stream reach types were A3, A4, B3 and B4. Abies grandis is the tree overstory dominant, although Picea engelmannii can sometimes be codominant. Shrub cover is generally sparse, but occasionally a few species may be abundant. Trautvetteria caroliniensis forms a carpet in the herbaceous understory. Other herbaceous species are scattered, generally at low cover. The most commonly occurring herbs are Maianthemum stellatum, Osmorhiza berteroi, Viola glabella, Fragaria vesca, Thalictrum alpinum, Galium triflorum, and Arnica cordifolia. Height of shrub layer averages 1.8 m, ranging from 0.9-3.7 m. Height of the herbaceous layer averages 51 cm, ranging from 31 to 91 cm. Herbaceous biomass averages 223 lbs/acre, ranging from 168-321 lbs/acre. Moderate fires will kill Abies grandis and Picea engelmannii on sites. The other common shrubs and herbs will survive fire and re-sprout or re-seed. Shrub cover may become more unless competition from Trautvetteria caroliniensis plants prevents shrub seedlings from becoming established.
