Pinus roxburghii

[citation needed] Chir pine is widely planted for timber in its native area, being one of the most important trees in forestry in northern Pakistan, India and Nepal.

When this species of pine tree reaches a large girth, the bark forms flat patches which can be broken off in chunks of about 52 cm2 (8 sq in) by 51 mm (2 in) thick[clarify].

This makes the wood become brightly coloured (various shades from translucent yellow to dark red) and very aromatic with a brittle, glassy feel.

They use it for starting fires and even for lighting, as a small piece of the wood burns for a long time (owing to the high resin content).

[citation needed] Every autumn, the dried needles of this tree form a dense carpet on the forest floor, which the locals gather in large bundles to serve as bedding for their cattle, for the year round.

It is also occasionally used as an ornamental tree, planted in parks and gardens in hot dry areas, where its heat and drought tolerance is valued.

The turpentine is chiefly used as a solvent in pharmaceutical preparations, perfume industry, in manufacture of synthetic pine oil, disinfectants, insecticides and denaturants.

It is one of the most important basic raw materials for the synthesis of terpene chemicals which are used in a wide variety of industries such as adhesives, paper and rubber, etc.

Besides these, other uses include manufacture of linoleum, explosives, insecticides and disinfectants, as a flux in soldering, in brewing and in mineral beneficiation as a frothing agent.
