Pinus brutia is a medium-size tree, reaching 20–35 metres (66–115 feet) tall with a trunk diameter of up to 1 m (3 + 1 ⁄ 2 ft), exceptionally 2 m (6 + 1 ⁄ 2 ft). The young bark is thin and red-orange, maturing to grey-brown to orange in color, fissured to flaky in texture.
Pinus wallichiana is a coniferous evergreen tree native to the Himalaya, Karakoram and Hindu Kush mountains, from eastern Afghanistan east across northern Pakistan and north west India to Yunnan in southwest China. It grows in mountain valleys at altitudes of 1800–4300 m (rarely as low as 1200 m), reaching 30–50 m (98–164 ft) in height.
The leaves are spirally arranged, scale-like or awl-like, 6–12 centimetres (2–5 in) long and 1.5–2 cm (5 ⁄ 8 – 3 ⁄ 4 in) broad at the base, with a sharp tip; leaves on young trees are shorter (under 9 cm or 4 in) and narrower (under 1.5 cm or 5 ⁄ 8 in).

Only about 40% of the ecoregion is covered in vegetation, generally shrubs, herbaceous cover, and open forest. The forest type is mostly determined by altitude zones. From 2,100-2,500 meters elevation the forest is drier, with Chilgoza pine (Pinus gerardiana), holly oak (Quercus baloot), species of the beech family , and cedar .
In the United States the pine tree Pinus palustris, known as the longleaf pine, once covered as much as 90,000,000 acres (360,000 km 2) but due to timber harvesting was reduced by between 95% and 97%. The trees grow very large (up to 150 feet), taking 100 to 150 years to mature and can live up to 500 years.
Pinus sabiniana trees typically grow to 11–14 metres (36–45 ft), but can reach 32 m (105 ft). The pine needles are in fascicles (bundles) of three, distinctively pale gray-green, sparse and drooping, and grow to 20–30 centimetres (8–12 in) in length.
The knobcone pine can be found growing in the dry, rocky soils of southern Oregon and northern California, between 300 and 750 m (980 and 2,460 ft) above sea level. [4] It forms nearly pure stands, preferring to grow where there is no competition. [4]
