Pinus roxburghii, commonly known as Chir Pine, is a large coniferous tree native to the Himalayas. It is a prominent species in the region, reaching heights of 30-50 meters and featuring a distinctive, deeply fissured bark that becomes thinner and flaky in the upper crown. The leaves are needle-like, arranged in fascicles of three, and are slender, measuring 20-35 cm in length. The cones are ovoid-conic, 12-24 cm long, and ripen to a glossy chestnut-brown.
Pinus roxburghii generally grows at altitudes between 500-2,000 meters, occasionally reaching up to 2,300 meters. This species is common in the outer ranges of the Himalayas, where it forms pure stands on dry, fire-prone slopes. The tree’s adaptability and resilience make it an important component of its ecosystem.
