Name: Alnus rubra / Adiantum pedatum Forest
Reference: Western Ecology Working Group of...
Description: <i>Alnus rubra / Adiantum pedatum</i> is an early-seral community type that occurs on well-drained, moderate to steep mid to lower slopes and toeslopes at 490 to 915 m (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 <i>Alnus rubra</i>-dominated stands. <i>Alnus rubra / Adiantum pedatum</i> stands are typically the result of the rapid establishment and domination by <i>Alnus rubra</i> following stand-replacing disturbance (such as an intense wildfire or a landslide). The even-aged <i>Alnus rubra</i> form a single-layered, dense deciduous forest canopy. Understory shrub associates include <i>Acer glabrum, Rosa gymnocarpa, Rubus parviflorus, Symphoricarpos mollis</i>, and <i>Vaccinium membranaceum</i>. Herbaceous species with a strong affinity to the community are <i>Adiantum pedatum, Anemone piperi, Asarum caudatum, Athyrium filix-femina, Circaea alpina, Clintonia uniflora, Coptis occidentalis, Cornus canadensis, Gymnocarpium dryopteris, Polystichum munitum, Streptopus amplexifolius</i>, and <i>Tiarella trifoliata var. unifoliata</i>.
