An alpine tree line is the highest elevation that sustains trees; higher up it is too cold, or the snow cover lasts for too much of the year, to sustain trees. [ 2 ] : 151 The climate above the tree line of mountains is called an alpine climate , [ 14 ] : 21 and the habitat can be described as the alpine zone . [ 15 ]
Krummholz Pinus albicaulis in Wenatchee National Forest Wind-sculpted krummholz trees, Ona Beach, Oregon. Krummholz (German: krumm, "crooked, bent, twisted" and Holz, "wood") — also called knieholz ("knee timber") — is a type of stunted, deformed vegetation encountered in the subarctic and subalpine tree line landscapes, shaped by continual exposure to fierce, freezing winds.
This is a list of Southern African trees, shrubs, suffrutices, geoxyles and lianes, and is intended to cover Angola, Botswana, Eswatini, Lesotho, Malawi, Mozambique, Namibia, South Africa, Zambia and Zimbabwe. [1] The notion of 'indigenous' is of necessity a blurred concept, and is clearly a function of both time and political boundaries.
Pinus mugo is widely cultivated as an ornamental plant, for use as a small tree or shrub, planted in gardens and in larger pots and planters. It is also used in Japanese garden style landscapes, and for larger bonsai specimens. In Kosovo, its trunk is used as construction material for the vernacular architecture in the mountains called "Bosonica".
Dendrology (Ancient Greek: δένδρον, dendron, "tree"; and Ancient Greek: -λογία, -logia, science of or study of) or xylology (Ancient Greek: ξύλον, ksulon, "wood") is the science and study of woody plants (trees, shrubs, and lianas), specifically, their taxonomic classifications. [1]
Rare living Trail Marker Tree in White County, Indiana, known as 'Grandfather' Trail trees, trail marker trees, crooked trees, prayer trees, thong trees, or culturally modified trees are hardwood trees throughout North America that Native Americans intentionally shaped with distinctive characteristics that convey that the tree was shaped by human activity rather than deformed by nature or ...
In botany, the trunk (or bole) is the stem and main wooden axis of a tree, [1] which is an important feature in tree identification, and which often differs markedly from the bottom of the trunk to the top, depending on the species. The trunk is the most important part of the tree for timber production.
On exposed tree line sites, mature trees are much smaller, reaching heights of only 5–10 m (15–35 ft). [8] In steeply-sloping, rocky, and windswept terrain in the Rocky Mountains of southern Alberta, limber pine is even more stunted, occurring in old stands where mature trees are consistently less than 3 m (10 ft) in height.
