Name: Alnus rubra / Adiantum pedatum Forest Reference: Western Ecology Working Group of... Description: Alnus rubra / Adiantum pedatum is an early-seral community type that occurs on well-drained, moderate to steep mid to lower slopes and toeslopes at 1600-3000 feet elevation. Sites are usually influenced by cold-air drainage. The community type occurs within the warmest extreme of the inland maritime climatic regime. Sites occur within a region of rugged topography. A history of repeated natural mass-wasting and alluvial deposition is apparent in these steep v-shaped valleys. These mass-wasting disturbance events occur with sufficient frequency to maintain the early-seral Alnus rubra-dominated stands. Alnus rubra / Adiantum pedatum stands are typically the result of the rapid establishment and domination by Alnus rubra following stand-replacing disturbance (such as an intense wildfire or a landslide). The even-aged Alnus rubra form a single-layered, dense deciduous forest canopy. Understory shrub associates include Acer glabrum, Rosa gymnocarpa, Rubus parviflorus, Symphoricarpos mollis, and Vaccinium membranaceum. Herbaceous species with a strong affinity to the community are Adiantum pedatum, Anemone piperi, Asarum caudatum, Athyrium filix-femina, Circaea alpina, Clintonia uniflora, Coptis occidentalis, Cornus canadensis, Gymnocarpium dryopteris, Polystichum munitum, Streptopus amplexifolius, and Tiarella trifoliata var. unifoliata.  Accession Code: VB.CC.24160.ALNUSRUBRAADIAN Plot-observations of this Community Concept: 0
