Name: Abies x shastensis / Vaccinium membranaceum / Chimaphila umbellata Forest
Reference: Western Ecology Working Group of...
Description: This association occurs in Oregon and California. The forests have a multi-storied tree canopy with high cover of shrubs. It averages 1630 m (5342 feet) elevation with slopes ranging 5-30% on predominantly northwestern aspects. Soil tends to be ash or basalt with the former being less productive. <i>Abies x shastensis</i> dominates the tree canopy with an average 29-39% cover. Usually present are <i>Pinus contorta</i> (0-26%), <i>Tsuga mertensiana</i> (0-9%), <i>Pseudotsuga menziesii</i> (0-31%), and <i>Pinus monticola</i> (0-4%). The shrub layer averages 53% cover and is characterized by <i>Vaccinium membranaceum</i> (26-30%) and <i>Chimaphila umbellata</i> (7-12%). Herb cover is generally low (8%) with <i>Orthilia secunda (= Pyrola secunda)</i> (2%) and <i>Anemone deltoidea</i> (1%) often present. Grasses are usually absent. This association resembles ~<i>Abies concolor / Vaccinium membranaceum</i> Forest (CEGL000264)$$, but is taller and has significant <i>Abies x shastensis</i> cover. The association also resembles ~<i>Abies concolor - Abies x shastensis / Chimaphila umbellata</i> Forest (CEGL000030)$$, but has a better developed understory. The ~<i>Abies x shastensis / Carex inops</i> ssp. <i>inops</i> Forest (CEGL000348)$$ is also similar except for the presence of <i>Carex inops ssp. heliophila</i>.
