The Sierra Nevada upper montane forest is a vegetation type found below the treeline in the United States Sierra Nevada range. [1] It is generally located above the mixed coniferous forest and below the alpine zone. [1] Overstory trees are typically cone shaped to shed the snow. [1]
Characteristic trees including lodgepole pine ( Pinus contorta ), Jeffrey pine ( Pinus jeffreyi ), western white pine ( Pinus monticola ) California red fir ( Abies magnifica ), and Sierra juniper ( Juniperus grandis ), and typical understory trees and shrubs such as huckleberry oak ( Quercus vaccinifolia ) and red heather ( Phyllodoce breweri ). [1]
On the western slopes of the Sierra Nevada range, upper montane vegetation can be found at elevations from 5,500 to 7,500 feet (1,700 to 2,300 m) in the northern part of the range, 6,500 to 8,000 feet (2,000 to 2,400 m) in the central part, and 8,000 to 10,000 feet (2,400 to 3,000 m) in the southern part. [1] On the eastern slopes, it is at higher elevations. Precipitation in areas of upper montane forest vegetation type is 35 to 65 feet (11 to 20 m), mostly as snowfall. [1] Summer high temperatures range from 73 to 85 °F (23 to 29 °C), and winter lows are below 26 °F (−3 °C). [1] Growing season is about four months because of long-lasting, deep snow. [1]
The Great Basin Desert is part of the Great Basin between the Sierra Nevada and the Wasatch Range. The desert is a geographical region that largely overlaps the Great Basin shrub steppe defined by the World Wildlife Fund, and the Central Basin and Range ecoregion defined by the U.S. Environmental Protection Agency and United States Geological Survey. It is a temperate desert with hot, dry summers and snowy winters. The desert spans a large part of the state of Nevada, and extends into western Utah, eastern California, and Idaho. The desert is one of the four biologically defined deserts in North America, in addition to the Mojave, Sonoran, and Chihuahuan Deserts.
The tree line is the edge of the habitat at which trees are capable of growing. It is found at high elevations and high latitudes. Beyond the tree line, trees cannot tolerate the environmental conditions. The tree line is sometimes distinguished from a lower timberline or forest line, which is the line below which trees form a forest with a closed canopy.
Pinus flexilis, the limber pine, is a species of pine tree-the family Pinaceae that occurs in the mountains of the Western United States, Mexico, and Canada. It is also called Rocky Mountain white pine.
The Peninsular Ranges are a group of mountain ranges that stretch 1,500 km (930 mi) from Southern California to the southern tip of the Baja California Peninsula; they are part of the North American Coast Ranges, which run along the Pacific Coast from Alaska to Mexico. Elevations range from 500 to 10,834 feet.
The ecology of the Sierra Nevada, located in the U.S. states of California and Nevada, is diverse and complex: the plants and animals are a significant part of the scenic beauty of the mountain range. The combination of climate, topography, moisture, and soils influences the distribution of ecological communities across an elevation gradient from 500 to 14,500 feet. Biotic zones range from scrub and chaparral communities at lower elevations, to subalpine forests and alpine meadows at the higher elevations. Particular ecoregions that follow elevation contours are often described as a series of belts that follow the length of the Sierra Nevada. There are many hiking trails, paved and unpaved roads, and vast public lands in the Sierra Nevada for exploring the many different biomes and ecosystems.
Eldorado National Forest is a U.S. National Forest located in the central Sierra Nevada mountain range, in eastern California.
The Sierra Nevada subalpine zone refers to a biotic zone below treeline in the Sierra Nevada mountain range of California, United States. This subalpine zone is positioned between the upper montane zone at its lower limit, and tree line at its upper limit.
The South Sierra Wilderness is a federally designated wilderness area in the Southern Sierra Nevada, in eastern California. It is located 65 miles (105 km) northeast of Bakersfield, and is southwest of Owens Lake and Olancha.
The climate and ecology of land immediately surrounding the Mediterranean Sea is influenced by several factors. Overall, the land has a Mediterranean climate, with mild, rainy winters and hot, dry summers. The climate induces characteristic Mediterranean forests, woodlands, and scrub vegetation. Plant life immediately near the Mediterranean is in the Mediterranean Floristic region, while mountainous areas further from the sea supports the Sub-Mediterranean Floristic province.
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.
Pinyon–juniper woodland, also spelled piñon–juniper woodland, is a vegetation type (biome) of Western United States higher elevation deserts, characterized by being an open forest dominated by low, bushy, evergreen junipers, pinyon pines, and their associates which vary from region to region. The woodland's crown height may vary from less than 10 meters up to 15 meters, depending on the site. It may consist of pure stands of pinyon pine, or pure stands of juniper.
The Great Basin montane forests is an ecoregion of the Temperate coniferous forests biome, as designated by the World Wildlife Fund (WWF).
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply.
Mixed coniferous forest is a vegetation type dominated by a mixture of broadleaf trees and conifers. It is generally located in mountains, below the upper montane vegetation type.
Foothill woodland is a California vegetation type characterized by an overstory of broadleaf and coniferous trees, generally found in areas of higher elevations and more precipitation than grasslands and oak savannah, and at lower elevations and less precipitation than mixed coniferous.
The upper montane forest is a vegetation type generally found above the mixed coniferous forest and below the subalpine forest vegetation types. Most of what grows in upper montane forests are conifers, because of the short growing season.
The flora of the U.S. Sierra Nevada alpine zone is characterized by small, low growing, cushion and mat forming plants that can survive the harsh conditions in the high-altitude alpine zone above the timber line. These flora often occur in alpine fell-fields. The Sierra Nevada alpine zone lacks a dominant plant species that characterizes it, so may or may not be called a vegetation type. But it is found above the subalpine forest, which is the highest in a succession of recognized vegetation types at increasing elevations.
