Name: Abies magnifica var. shastensis / Vaccinium membranaceum / Chimaphila umbellata Forest
Reference: NatureServe Biotics 2019
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 magnifica var. shastensis</i> dominates the tree canopy with an average 29-39% cover. Usually present are <i>Pinus contorta, Tsuga mertensiana, Pseudotsuga menziesii</i>, and <i>Pinus monticola</i>. The shrub layer averages 53% cover and is characterized by <i>Vaccinium membranaceum</i> and <i>Chimaphila umbellata</i>. Herb cover is generally low (8%) with <i>Orthilia secunda</i> and <i>Anemone deltoidea</i> often present. Grasses are usually absent. This association resembles ~<i>Abies lowiana / Vaccinium membranaceum</i> Forest (CEGL000264)$$, but is taller and has significant <i>Abies magnifica var. shastensis</i> cover. It also resembles ~<i>Abies lowiana - Abies magnifica var. shastensis / Chimaphila umbellata</i> Forest (CEGL000030)$$, but has a better developed understory. ~<i>Abies magnifica var. shastensis / Carex inops ssp. inops</i> Forest (CEGL000348)$$ is also similar except for the presence of <i>Carex inops ssp. heliophila</i>.
