Pinus durangensis (Durango Pine)

Pinus durangensis (Durango Pine) is a species of pine tree native to the Sierra Madre Occidental mountain range in Mexico. It is a medium-sized evergreen conifer with a restricted distribution in the state of Durango, Mexico.

Size and Growth Habit: Durango Pine typically grows to a height of 20-25 meters (65-82 feet), although some specimens can reach up to 35 meters (115 feet). It has a straight trunk with a relatively narrow and conical crown. The branches are often ascending and arranged in regular whorls.

Needles: The needles of Pinus durangensis are dark green and occur in bundles of two. They are slender and measure about 15-25 cm (6-10 inches) in length. The needles persist on the tree for several years before eventually shedding.

Cones: The cones of Durango Pine are medium-sized and elongated, ranging from 8-15 cm (3-6 inches) in length. They have a conical shape with thick, woody scales. The cones are initially green and mature to a light brown color. They contain winged seeds that are dispersed by wind.

Habitat: Durango Pine is endemic to the state of Durango in north-central Mexico. It grows in mountainous regions at elevations of 2,000-3,000 meters (6,500-9,800 feet) above sea level. It prefers well-drained soils and is often found in mixed coniferous forests with other tree species.

Ecological Importance: Pinus durangensis is an important component of the montane forest ecosystems in its native range. It provides habitat and food sources for various wildlife species, including birds and mammals. The tree also helps stabilize soil, prevents erosion, and contributes to the overall biodiversity of the region.

Conservation Status: Pinus durangensis is considered a vulnerable species due to its restricted distribution and habitat loss. It faces threats from deforestation, illegal logging, and changes in land use. Conservation efforts are underway to protect and preserve the remaining populations of Durango Pine.
