Although, at first glance, muskeg resembles a plain covered with short grasses, a closer look reveals a bizarre and almost unearthly landscape. Small stands of stunted (often-dead) trees, which vaguely resemble natural bonsai, grow where land protrudes above the water table, with small pools of water (stained dark red) scattered about.
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.
Acacia, commonly known as wattles [3] [4] or acacias, is a genus of about 1,084 species of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa, South America, and Australasia , but is now reserved for species mainly from Australia, with others from New ...
Trees in the genus are often large and slow-growing; Q. alba can reach an age of 600 years, a diameter of 13 feet (4.0 m) and a height of 145 feet (44 m). [8] The Granit oak in Bulgaria, a Q. robur specimen, has an estimated age of 1,637 years, making it the oldest oak in Europe. [ 9 ]
The flora of the alpine tundra is characterized by plants that grow close to the ground, including perennial grasses, sedges, forbs, cushion plants, mosses, and lichens. [28] The flora is adapted to the harsh conditions of the alpine environment, which include low temperatures, dryness, ultraviolet radiation, and a short growing season.
It can grow into a massive tree with many examples hundreds of years old. Around ten trees are known from the past and present with a diameter of 4 m (13 ft) or more with several specimens around 100 m 3 (3,500 cu ft) in total volume. [5] Like other plane trees, its leaves are borne alternately on the stem, deeply lobed, and palmate or maple ...

The leaves are variable, being 15–25 mm (5 ⁄ 8 –1 in) long and flat on young trees and shaded lower branches in older trees. The leaves are scalelike, 5–10 mm ( 1 ⁄ 4 – 3 ⁄ 8 in) long on shoots in full sun in the upper crown of older trees, with a full range of transition between the two extremes.
