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.
Firs are evergreen coniferous trees belonging to the genus Abies in the family Pinaceae. There are approximately 48–65 extant species, found on mountains throughout much of North and Central America, Europe, Asia, and North Africa. The genus is most closely related to Cedrus (cedar)The genus name is derived from the Latin "to rise" in reference to the height of its species. The common English name originates with the Old Norse, fyri, or the Old Danish, fyr.
Alnus rubra, the red alder, is a deciduous broadleaf tree native to western North America.
Abies balsamea or balsam fir is a North American fir, native to most of eastern and central Canada and the northeastern United States.
Abies nordmanniana, the Nordmann fir or Caucasian fir, is a fir indigenous to the mountains south and east of the Black Sea, in Turkey, Georgia and the Russian Caucasus. It occurs at altitudes of 900–2,200 m on mountains with precipitation of over 1,000 mm.
Abies alba, the European silver fir or silver fir, is a fir native to the mountains of Europe, from the Pyrenees north to Normandy, east to the Alps and the Carpathians, Slovakia, Slovenia, Croatia, Bosnia and Herzegovina, Montenegro, Serbia, and south to Italy, Bulgaria, Kosovo, Albania and northern Greece; it is also commonly grown on Christmas tree plantations in the North East region of North America spanning New England in the US to the Maritime provinces of Canada.
Pseudolarix amabilis is a species of coniferous tree in the pine family Pinaceae. The species is commonly known as golden larch, but being more closely related to Keteleeria, Abies and Cedrus, is not a true larch (Larix). P. amabilis is native to eastern China, occurring in small areas in the mountains of southern Anhui, Zhejiang, Fujian, Jiangxi, Hunan, Hubei and eastern Sichuan, at altitudes of 100–1,500 m (328–4,921 ft). The earliest known occurrences are of compression fossils found in the Ypresian Allenby Formation and mummified fossils found in the Late Eocene Buchanan Lake Formation on Axel Heiberg Island.
Abies concolor, the white fir, concolor fir, or Colorado fir, is a coniferous tree in the pine family Pinaceae. This tree is native to the mountains of western North America, including the Sierra Nevada and southern Rocky Mountains, and into the isolated mountain ranges of southern Arizona, New Mexico, and Northern Mexico. It naturally occurs at elevations between 900 and 3,400 metres.
Tsuga heterophylla, the western hemlock or western hemlock-spruce, is a species of hemlock native to the west coast of North America, with its northwestern limit on the Kenai Peninsula, Alaska, and its southeastern limit in northern Sonoma County, California. The Latin species name means 'variable leaves'.
Picea engelmannii, with the common names Engelmann spruce, white spruce, mountain spruce, and silver spruce, is a species of spruce native to western North America. It is mostly a high-elevation mountain tree but also appears in watered canyons.
Abies magnifica, the red fir or silvertip fir, is a western North American fir, native to the mountains of southwest Oregon and California in the United States. It is a high-elevation tree, typically occurring at 1,400–2,700 metres (4,600–8,900 ft) elevation, though only rarely reaching tree line. The name red fir derives from the bark color of old trees.
Abies procera, the noble fir, also called red fir and Christmas tree, is a species of fir native to the Cascade Range and Pacific Coast Ranges of the northwestern Pacific Coast of the United States. It occurs at altitudes of 300–1,500 meters (980–4,920 ft).
Abies lasiocarpa, the subalpine fir or Rocky Mountain fir, is a western North American fir tree.
Abies amabilis, commonly known as the Pacific silver fir, is a fir native to the Pacific Northwest of North America, occurring in the Pacific Coast Ranges and the Cascade Range. It is also commonly referred to in English as the white fir, red fir, lovely fir, amabilis fir, Cascades fir, or silver fir. The species name is Latin for 'lovely'.
The western larch is a species of larch native to the mountains of western North America ; in Canada in southeastern British Columbia and southwestern Alberta, and in the United States in eastern Washington, eastern Oregon, northern Idaho, and western Montana. It is the most productive of the three species of larch native to North America.
Abies koreana, the Korean fir, is a species of fir native to the higher mountains of South Korea, including Jeju Island. It grows at altitudes of 1,000–1,900 metres (3,300–6,200 ft) in temperate rainforest with high rainfall and cool, humid summers, and heavy winter snowfall.
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 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.
