Chilgoza
Chilgoza trees are 15–25 meters (49–82 ft), usually crowned deep, wide, and open with long, erect branches.
Crowns are narrower and shallower in dense forests. The bark is very flaky, peeling to light greyish-green patches. Branchlets are smooth and olive-green.
The leaves are needle-like, in groups of three, 6–10 centimeters (2.4–3.9 in) long, and stiffly spread.
They possess a shiny green outer surface and bluish-green stomatal lines on the inner face; their sheaths shed in the first year.
Cones 10–18 cm long, 9–11 cm wide when open with wrinkled reflexed apophyses and an umbo curved inward at the base.
The seeds (pine nuts) are 17–23 millimeters (0.67–0.91 in) long and 5–7 millimeters (0.20–0.28 in) broad, with a thin shell and a rudimentary wing.[3]

Similar species
Chilgoza P. gerardiana is similar to the closely related lacebark pine (Pinus bungeana), another pine with flaking bark. However, P. gerardiana has denser, longer, and more slender needles, as well as larger cones than P. bungeana.[4]
Taxonomy
Chilgoza botanical name is named for Captain Patrick Gerard, a British army officer in the Bengal Native Infantry.[4] who gathered it during an 1823–25 military survey of India.[3]
It was first described in A.B. Lambert, Descr. Pinus, ed. 3, 2: 144 bis in 1832.[2]
Distribution and habitat
P. gerardiana is found in Afghanistan, Tibet, China, Jammu-Kashmir, India, and Pakistan.
It grows at high altitudes so it occupies valley floors between high mountain ranges in the Himalayas, and tends to increase among open vegetation on dry sunny slopes.

Conservation Status
Chilgoza species has been classified as nearly threatened in the IUCN Red List of Threatened Species published in 2011. It was Lower Risk/near threatened in 1998.
P. gerardia forests have declined by an estimated 30% due to the conversion of pine forests to farmland, intensive grazing, and over-harvesting of seed cones and timber for firewood.[1] .
The Himachal Pradesh State Forest Department has tried artificial regeneration of chilgoza pine in many places. However, the performance of seedlings was found to be very poor.[citation needed]

Ecology
Tree Since their seeds do not have a wing that can enable them to be dispersed effectively by the wind, P. gerardiana seeds are dispersed by birds.[1] One such bird is the Eurasian nutcracker, specifically the subsp. multipunctata of Nucifraga caryocatactes. [3]
P. gerardiana is a secondary host to Himalayan dwarf mistletoe. [5]
Uses
Chilgoza Older trees that do not produce enough cones to collect pine nuts are logged as firewood. The logs are also used in local light construction and carpentry.[1]
Food
More about Pine nut
Chilghoza seeds, or pine nuts, are harvested for consumption in the fall and early winter by knocking the cones off the trees.
In some localities, they are owned by mountain clans and villages and exported to northern Indian plains markets.
Under traditional harvesting, enough seeds are left behind to allow the forest to regenerate, although in areas controlled by private contractors, all cones are taken.
Chilgoza pine nuts contain carbohydrates and proteins. The seeds are locally known and sold as “chilgoza”, “Neja” (singular), or “neje” (plural). Childhood is one of the most important cash crops of Afghanistan, [6][7][8] as well as of Kinnaur and Pangi Valley of Chamba district of Himachal Pradesh, India.[9] They are sold at around $20–$53 per kilogram in India.[citation needed]
