Taxonomy [top]

Kingdom Phylum Class Order Family
PLANTAE TRACHEOPHYTA PINOPSIDA PINALES PINACEAE

Scientific Name: Pinus roxburghii
Species Authority: Sarg.
Common Name/s:
English Chir Pine, Long-leaved Indian Pine

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2013
Date Assessed: 2011-01-31
Assessor/s: Farjon, A.
Reviewer/s: Thomas, P.
Justification:
This species must have had a reduction in area of occupancy and numbers of mature trees in the past due to over-exploitation, but matters appear to have improved due to better management of the forests. If there is still decline, it is probably insufficient to seriously impact this common and widespread species

Habitat and Ecology [top]

Habitat and Ecology: Pinus roxburghii is widespread and common in the north-south oriented outer valleys of the Himalaya and its foothills and often forms pure stands especially on dry, fire-prone slopes. Mature trees are relatively fire resistant; regeneration after destructive fires can be massive and rapid when it acts as a pioneer species. In prolonged dry seasons it may drop most of its leaves. It occurs on a variety of substrates, from deep soil to bare rocks. Its altitudinal range is from 400 m to 2,300 m a.s.l., with the highest growing, scattered individuals at 2,500 m. Pinus roxburghii is restricted to the monsoon belt with summer rains. In its higher altitudinal range this pine species is commonly mixed with Cedrus deodara and Pinus wallichiana, but occurs below the forest zone characterized by species of Abies. Broad-leaved trees (angiosperms) are commonly Quercus incana, Schima wallichii and Rhododendron arboreum. Towards its lower limit angiosperms become more dominant and the pines occur on rocky slopes with a northern or eastern aspect.
Systems: Terrestrial

Threats [top]

Major Threat(s): While forest destruction and logging have reduced the area of occupancy (AOO) of P. roxburghii, it is still covering extensive areas (an estimated 0.87 million ha in India alone) and is therefore not considered to be threatened with extinction. Improved methods of resin tapping have decreased the risk of trees dying prematurely

Conservation Actions: This species occurs in some protected areas.
