CEGL008612 Abies magnifica - Pinus contorta var. murrayana / Hieracium albiflorum Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: California Red Fir - Sierra Lodgepole Pine / White Hawkweed Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This forest association occurs throughout the central and southern Sierra Nevada in California at all elevations of the upper montane, from 2380 to 2900 m (7800-9500 feet). Aspects are variable, but mostly northeast and northwest. Slopes are gentle or moderate. Stands are typically on benches, lower slopes, and in bottom positions adjacent to and somewhat upslope from flat areas such as meadow complexes or drainage bottoms. Stands in this type have significantly less bare ground and surface gravel as compared to most others in the upper montane of the Sierra Nevada. Microrelief is usually smooth and uniform to gently undulating. Stands of this association are dense, multi-layered forests with understories composed of patches of dense conifer regeneration. Average tree cover is one of the highest in the forests of the upper montane of the Sierra Nevada. The overstory is dominated by Abies magnifica in a mix with Pinus contorta var. murrayana. Understories are sparse; shrub cover is among the lowest in the upper montane forests, and shrubs occur in isolated patches or as scattered individuals. The herb layer usually has a mix of mesic and moist-site indicators, such as Hieracium albiflorum, Viola purpurea, Kelloggia galioides, Osmorhiza berteroi, and Poa bolanderi.

Classification Comments: This type is a common associate of ~Pinus contorta var. murrayana / Ligusticum grayi Forest (CEGL002747)$$, and environmentally, conditions in these two types are similar. However, the latter usually occurs on moister sites. Stands can cover extensive areas in gently rolling terrain and drainage bottoms, but usually they are smaller than 10 acres, and in some cases can be less than an acre.

Floristics: Stands of this association are dense, multi-layered forests with understories composed of patches of dense conifer regeneration. Average tree cover is one of the highest in the forests of the upper montane of the Sierra Nevada. The overstory is dominated by Abies magnifica, with an average 49% cover, in a mix with Pinus contorta var. murrayana, with an average 20% cover. Understories are sparse; shrub cover is among the lowest in the upper montane forests, and shrubs occur in isolated patches or as scattered individuals. The herb layer, which averages 8%, usually has a mix of mesic and moist-site indicators, such as the mesic indicators Hieracium albiflorum, Viola purpurea, and Kelloggia galioides, and the moist habitat indicators Osmorhiza berteroi (= Osmorhiza chilensis) and Poa bolanderi. Conifer regeneration is high, dominated by Abies magnifica.
