Sierra Nevada lower montane forest


The Sierra Nevada lower montane forest is a plant community along a strip along the western and eastern edges of the Sierra Nevada mountain range in California. This zone is also known as a yellow pine forest.
Moving southward, the elevation range of the lower montane forest grows. Its elevation range at the northern end of the Sierra is from. In the central Sierra, its elevation range is from. In the southern end of the Sierra, its range is from.
The daily high temperature in the summer is, while the daily lows in winter are around. Annual precipitation depends on elevation: Yosemite Valley at gets a year.
At the lower elevation of this forest, the hot, dry summers and cool, moist winters of the Mediterranean climate give rise to the lower montane forest zone. The accumulation of several feet of snow during the winter is not uncommon and can stay on the ground for several months. The diversity of tree species found in this zone make this a beautiful and interesting forest to explore. The indicator species for the lower montane forest are the ponderosa pine and the Jeffrey pine. Ponderosa pines are common in the west side forests at lower elevations. Jeffrey pines are commonly found in the East side forests at higher elevations and in drier areas.
The lower montane forests also include trees such as California black oak, sugar pine, incense-cedar, and white fir. The giant sequoia groves of the Sierra Nevada are also found within this biotic zone. Animals that may be found in this zone include the dark-eyed junco, mountain chickadee, western gray squirrel, mule deer, and American black bear. The lower montane forest can be seen in Yosemite Valley and along the Wawona, Hetch Hetchy, and Big Oak Flat Roads.
The lower montane forest consists of several layers:
Some threats to the lower montane forests include logging, grazing, changing fire regimes, fragmentation due to development, climate change, and pest outbreaks.
