Name: A.305
Reference: EcoArt 2002
Description: This forest alliance occurs on well-drained, moderate to steep mid to lower slopes and toeslopes from approximately 480-915 m in elevation. Sites are usually influenced by cold-air drainage. These ~Alnus rubra$-dominated stands occur within the warmest extreme of the inland maritime climatic regime, generally being restricted to very moist and warm sites. This region is characterized by rugged topography, and a history of repeated natural mass-wasting and alluvial deposition is apparent in these steep V-shaped valleys. These mass-wasting disturbance events occur with sufficient frequency to maintain the early-seral ~Alnus rubra$-dominated stands. These forest 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$ forms 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$, and ~Tiarella trifoliata var. unifoliata (= Tiarella unifoliata)$.
