Pinus contorta (var. latifolia, var. murrayana) / Vaccinium uliginosum Forest
Translated Name: (Tall Lodgepole Pine, Sierra Lodgepole Pine) / Bog Blueberry Forest
Unique Identifier: CEGL000171
Classification Approach: International Vegetation Classification (IVC)
Summary: This lodgepole pine forest association is currently known from Idaho, Oregon and California. This description is currently based on information from Yosemite National Park in California, Additional global information will be added as it becomes available. In Yosemite, this association is found along small streams and on the edges of meadows, or on slightly higher elevations in meadows, from approximately 2285-2925 m (7500-9600 feet) in elevation on gentle to moderate slopes of variable aspects. Soil textures range from silty loam of granitic origin to muck. Soils are somewhat poorly drained to poorly drained. Litter/duff cover ranges from 20-95%. Sites are palustrine. The tree layer is composed almost solely of Pinus contorta var. murrayana, ranging up to 35 m in height and up to 37% cover. Vaccinium uliginosum provides from 15-87% cover in the shrub layer, which is generally under 0.5 m. Other (sub)shrubs include Vaccinium cespitosum and Kalmia polifolia; Pinus contorta var. murrayana saplings are also present in the shrub layer. The herb layer is variable, with Carex utriculata providing most of the cover in this layer; other species include Mimulus primuloides, Juncus drummondii, and Oreostemma alpigenum var. alpigenum. Moss covers 5-40% of the ground.
