However, it is quite capable of survival and success in dry soils once it is established. 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.
Most mature trees have been cleared and the layer of leaf litter, with decaying matter enriching the soil, has begun to wash away with recent rains. The majority of the commercial timber growing and wood processing in the state of Texas takes place in the Piney Woods region, which contains about 50,000 square kilometres (12,000,000 acres) of ...
Pinus ponderosa subsp. readiana Robert Z. Callaham subsp. novo – central High Plains ponderosa pine; Southern South Dakota and adjacent northern Nebraska and far eastern Colorado, but neither the northern and southern High Plains nor the Black Hills, which are in P. p. scopulorum. Hot, dry, very windy summers; continental cold, wet winters.
In physical geography, tundra (/ ˈ t ʌ n d r ə, ˈ t ʊ n-/) is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. There are three regions and associated types of tundra: Arctic tundra, [2] alpine tundra, [2] and Antarctic tundra.
Pine barrens, pine plains, sand plains, or pineland areas occur throughout the U.S. from Florida to Maine (see Atlantic coastal pine barrens) as well as the Midwest, West, and Canada and parts of Eurasia. Perhaps the most well known pine-barrens area to North Americans is the New Jersey Pine Barrens. Pine barrens are generally pine forests in ...

Aspen trees are all native to cold regions with cool summers, in the north of the northern hemisphere, extending south at high-altitude areas such as mountains or high plains. They are all medium-sized deciduous trees reaching 15–30 m (50–100 ft) tall. In North America, the aspen is referred to as quaking aspen or trembling aspen because ...
It is a very slow growing species and can live up to 200 years. Saplings and juvenile trees have a conifer-like habit and can take 3 years to reach a height of 1 metre (3 ft). [6] Some individuals are estimated to live over 500 years. [4] Inflorescences are simple and axillary supported on peduncles 12 to 15 mm (0.5 to 0.6 in) long.
