CEGL008613 Abies magnifica - Pinus monticola Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: California Red Fir - Western White Pine Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: These forests are located at higher elevations throughout the central and southern Sierra Nevada, California. This association most frequently occurs above 2590 m (8500 feet) in elevation. Aspects can be varied, but sites typically face northeast and northwest. Most stands are on slopes that are somewhat steep or less. This association occurs predominantly on ridges and upper and middle slope positions where microrelief is smooth and uniform. Soils are generally derived from granite, but parent materials may be volcanic, sedimentary, metamorphic, or mixed. Stands are moderately dense forests with little understory vegetation. Tree cover is significantly higher than other stands with Pinus monticola. Overstory layers are characterized by the presence of Pinus monticola in a mix with Abies magnifica. In rare stands Pinus monticola may comprise nearly 50% of the crown cover, but generally red fir has the highest cover values. Understories are quite open. The shrub layer is essentially absent. The sparse forb component is distinguished by the presence of Eucephalus breweri and Arabis platysperma, indicating dry sites. Monardella odoratissima and Erysimum capitatum var. perenne are other herbs that may be present. Conifer regeneration is high, dominated by Abies magnifica.

Floristics: Stands are moderately dense forests with little understory vegetation. Tree cover is significantly higher than other stands with Pinus monticola. Overstory layers are characterized by the presence of Pinus monticola in a mix with Abies magnifica. In rare stands Pinus monticola may comprise nearly 50% of the crown cover, but generally red fir has the highest cover values. Understories are quite open. The shrub layer is essentially absent. The sparse forb component is distinguished by the presence of Eucephalus breweri (= Chrysopsis breweri) and Arabis platysperma, indicating dry sites. Monardella odoratissima and Erysimum capitatum var. perenne (= Erysimum perenne) are other herbs that may be present. Conifer regeneration is high, dominated by Abies magnifica.

Environmental Description: This association most frequently occurs above 2590 m (8500 feet) in elevation. Aspects can be varied, but sites typically face northeast and northwest. Most stands are on slopes that are somewhat steep or less. This association occurs predominantly on ridges and upper and middle slope positions where microrelief is smooth and uniform. Soils are generally derived from granite, but parent materials may be volcanic, sedimentary, metamorphic, or mixed. Soils are moderately deep to deep and are commonly sandy loams, and are either well-drained or excessively drained.
Geographic Range: These forests are located at higher elevations throughout the central and southern Sierra Nevada, California. Stands can be somewhat extensive, but in most cases they appear to be less than 50 acres in size. It becomes more abundant south of Kaiser Pass (southern Sierra) where Tsuga mertensiana begins to lose abundance regionally (Potter 1994, 1998).
