Pseudotsuga is a genus of evergreen coniferous trees in the family Pinaceae. Common names for species in the genus include Douglas fir, Douglas-fir, Douglas tree, Oregon pine and Bigcone spruce. Pseudotsuga menziesii is widespread in western North America and is an important source of timber. The number of species has long been debated, but two in western North America and two to four in eastern Asia are commonly acknowledged.
Pseudotsuga macrocarpa, commonly called the bigcone spruce or bigcone Douglas-fir, is an evergreen conifer native to the mountains of southern California. It is notable for having the largest cones in the genus Pseudotsuga, hence the name.
The Douglas fir is an evergreen conifer species in the pine family, Pinaceae. It is native to western North America and is also known as Douglas-fir, Douglas spruce, Oregon pine, and Columbian pine. There are three varieties: coast Douglas-fir, Rocky Mountain Douglas-fir and Mexican Douglas-fir.
Pseudotsuga menziesii var. glauca, or Rocky Mountain Douglas-fir, is an evergreen conifer native to the interior mountainous regions of western North America, from central British Columbia and southwest Alberta in Canada southward through the United States to the far north of Mexico. The range is continuous in the northern Rocky Mountains south to eastern Washington, eastern Oregon, Idaho, western and south-central Montana and western Wyoming, but becomes discontinuous further south, confined to "sky islands" on the higher mountains in Utah, Colorado, Arizona and New Mexico, with only very isolated small populations in eastern Nevada, westernmost Texas, and northern Mexico. It occurs from 600 m altitude in the north of the range, up to 3,000 m, rarely 3,200 m, in the south. Further west towards the Pacific coast, it is replaced by the related coast Douglas-fir, and to the south, it is replaced by Mexican Douglas-fir in high mountains as far south as Oaxaca. Some botanists have grouped Mexican Douglas-fir with P. menziesii var. glauca, but genetic and morphological evidence suggest that Mexican populations should be considered a different variety.
Quercus garryana is an oak tree species of the Pacific Northwest, with a range stretching from southern California to southwestern British Columbia. It is commonly known as the Garry Oak, Oregon white oak or Oregon oak. It grows from sea level to an altitude of 690 feet in the northern part of its range, and from 980 to 5,900 ft in the south of the range in California. The eponymous Nicholas Garry was deputy governor of the Hudson's Bay Company.
Temperate rainforests are rainforests with coniferous or broadleaf forests that occur in the temperate zone and receive heavy rain.
Arbutus menziesii or Pacific madrone, is a species of broadleaf evergreen tree in the family Ericaceae. It has waxy foliage, a contorted growth habit, and flaky bark.
The Northern California coastal forests are a temperate coniferous forests ecoregion of coastal Northern California and southwestern Oregon.
Waddell Creek is the name given to both the creek and the watershed that run through Big Basin Redwoods State Park in Santa Cruz County, California. The Waddell Creek mainstem is formed by the confluence of East and West Waddell Creeks, and empties into the Pacific Ocean at Waddell Beach, just south of Año Nuevo Point.
The Sierra Madre Occidental pine–oak forests are a Temperate broadleaf and mixed forests ecoregion of the Sierra Madre Occidental range from the southwest USA region to the western part of Mexico. They are home to a large number of endemic plants and important habitat for wildlife.
California mixed evergreen forest is a plant community found in the mountain ranges of California and southwestern Oregon.
The Carmel River is a 41 mi (66 km) river on the Central Coast of California in Monterey County that originates in the Ventana Wilderness of the Santa Lucia Mountains. The river flows northwest through Carmel Valley with its mouth at the Pacific Ocean south of Carmel-by-the-Sea, at Carmel Bay. The Carmel River is considered the northern boundary of Big Sur, the other boundaries being San Carpóforo Creek and the Pacific coastline.
The Ancient Forest Alliance is a grassroots environmental organization in British Columbia, Canada. It was founded in January 2010, and is dedicated to protecting British Columbia's old-growth forests in areas where they are scarce, and ensuring sustainable forestry jobs in that province.
The Alberta Mountain forests are a temperate coniferous forests ecoregion of Western Canada, as defined by the World Wildlife Fund (WWF) categorization system.
Pseudotsuga menziesii var. menziesii, commonly known as Coast Douglas-fir, Pacific Douglas-fir, Oregon pine, or Douglas spruce, is an evergreen conifer native to western North America from west-central British Columbia, Canada southward to central California, United States. In Oregon and Washington its range is continuous from the Cascades crest west to the Pacific Coast Ranges and Pacific Ocean. In California, it is found in the Klamath and California Coast Ranges as far south as the Santa Lucia Mountains with a small stand as far south as the Purisima Hills, Santa Barbara County. In the Sierra Nevada it ranges as far south as the Yosemite region. It occurs from near sea level along the coast to 1,800 metres (5,900 ft) in the California Mountains. Further inland, coast Douglas-fir is replaced by Rocky Mountain or interior Douglas-fir. Interior Douglas-fir intergrades with coast Douglas-fir in the Cascades of northern Washington and southern British Columbia.
The Queets Fir is a superlative Douglas fir about 2.5 miles from the Queets River Trail trailhead, on Coal Creek, a tributary of Queets River in the Olympic National Park in Washington State. It was known for fifty years, beginning in 1945, as the largest known fir by volume, and is still largest known in diameter. It has a height of at least 200 feet (61 m), circumference 600 inches (15,000 mm), and spread of 71 feet (22 m). It was listed as national co-champion Douglas fir by American Forests, and one of only a handful of "undisputed megatrees" in North America with over 800 points.
The Lynn Valley Tree was one of the tallest known Coast Douglas-fir, at a measured height of 126.5 meters (415 ft). It was cut down by the Tremblay Brothers, at Argyle Road in 1902 on the property of Alfred John Nye in Lynn Valley, now part of metropolitan Vancouver, B.C. It measured 4.34 meters (14.2 ft) across the butt, and the bark was 13.5 inches (34 cm) thick. Since that time, in the lower valley where the tree grew, the entire old-growth forest has been logged, including another tree felled in the same valley that was said to have measured 107 m (351 ft) tall.
The San Juan Valley is a small valley located in the Capital Regional District of Vancouver Island in British Columbia, Canada.
Big Lonely Doug is a large Coast Douglas-fir tree located in the Gordon River Valley, 10km north of Port Renfrew on Vancouver Island, British Columbia, Canada. It is the second largest Douglas-fir tree in Canada after the Red Creek Fir in nearby San Juan Valley.
