Pinus sabiniana, with the common names gray pine, foothill pine, and the more historically and internationally used digger pine, is a pine endemic to California in the United States. According to Conifers.org, "The terms 'foothills pine' or 'gray pine' are now officially preferred", however, other names also exist.
Western white pine also called silver pine, and California mountain pine, in the family Pinaceae, is a species of pine that occurs in the mountains of the western United States and Canada, specifically the Sierra Nevada, the Cascade Range, the Coast Range, and the northern Rocky Mountains. The tree extends down to sea level in many areas, particularly in Oregon and Washington. It is the state tree of Idaho, and is sometimes known as the Idaho pine.
The Klamath Mountains are a rugged and lightly populated mountain range in northwestern California and southwestern Oregon in the western United States. They have a varied geology, with substantial areas of serpentinite and marble, and a climate characterized by moderately cold winters with very heavy snowfall and warm, very dry summers with limited rainfall, especially in the south. As a consequence of the geology and soil types, the mountains harbor several endemic or near-endemic trees, forming one of the largest collections of conifers in the world. The mountains are also home to a diverse array of fish and animal species, including black bears, large cats, owls, eagles, and several species of Pacific salmon. Millions of acres in the mountains are managed by the United States Forest Service. The northernmost and largest sub-range of the Klamath Mountains are the Siskiyou Mountains.
Pinus lambertiana is the tallest and most massive pine tree, and has the longest cones of any conifer. The species name lambertiana was given by the British botanist David Douglas, who named the tree in honour of the English botanist, Aylmer Bourke Lambert. It is native to the mountains of the Pacific coast of North America, from Oregon through California to Baja California.
Pinus jeffreyi also known as Jeffrey pine, Jeffrey's pine, yellow pine and black pine, is a North American pine tree. It is mainly found in California, but also in the westernmost part of Nevada, southwestern Oregon, and northern Baja California. It is named in honor of its botanist documenter John Jeffrey.
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.
Pinus contorta, with the common names lodgepole pine and shore pine, and also known as twisted pine, and contorta pine, is a common tree in western North America. It is common near the ocean shore and in dry montane forests to the subalpine, but is rare in lowland rain forests. Like all pines, it is an evergreen conifer.
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 Coulter pine or big-cone pine, Pinus coulteri, is a native of the coastal mountains of Southern California and northern Baja California (Mexico). Isolated groves are found as far north as the San Francisco Bay Area in Mt. Diablo State Park and Black Diamond Mines Regional Preserve. The species is named after Thomas Coulter, an Irish botanist and physician.
The knobcone pine, Pinus attenuata, is a tree that grows in mild climates on poor soils. It ranges from the mountains of southern Oregon to Baja California with the greatest concentration in northern California and the Oregon-California border.
The bishop pine, Pinus muricata, is a pine with a very restricted range: mostly in California, including several offshore Channel Islands, and a few locations in Baja California, Mexico. It is always on or near the coast.
Pinus cembroides, also known as pinyon pine, Mexican pinyon, Mexican nut pine, and Mexican stone pine, is a pine in the pinyon pine group, native to western North America. It grows in areas with low levels of rainfall and its range extends southwards from Arizona, Texas and New Mexico in the United States into Mexico. It typically grows at altitudes between 1,600 and 2,400 metres. It is a small pine growing to about 20 m (66 ft) with a trunk diameter of up to 50 cm (20 in). The seeds are large and form part of the diet of the Mexican jay and Abert's squirrel. They are also collected for human consumption, being the most widely used pine nut in Mexico. This is a common pine with a wide range and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
The Diablo Range is a mountain range in the California Coast Ranges subdivision of the Pacific Coast Ranges. It is located in the eastern San Francisco Bay area south to the Salinas Valley area of northern California, the United States.
California mixed evergreen forest is an ecoregion of the Temperate broadleaf and mixed forests biome. It is found in the mountain ranges of California and into southwestern Oregon.
The Rocky Mountain Floristic Region, also known as the Rocky Mountain Floristic Province, is a floristic region within the Holarctic Kingdom in western North America delineated by Armen Takhtajan and Robert F. Thorne. The region extends from Kodiak Island in Alaska to the San Francisco Bay Area and Sierra Nevada in California. The Vancouverian Province comprises the coastal part of the region for its entire length, including the Pacific Coast Ranges, and the Rocky Mountain Province includes the Rocky Mountains and associated ranges. There are no endemic plant families in the region but many endemic genera and species.
The North Central Rockies forests is a temperate coniferous forest ecoregion of Canada and the United States. This region gets more rain on average than the South Central Rockies forests and is notable for containing the only inland populations of many species from the Pacific coast.
