The total area of cold desert is approximately 98,660 sq. km., of which about 82,665 sq. km can be found in Jammnu & Kashmir, about 15,000 sq. km. in Himachal Pradesh and nearly 1000 sq. km. in Uttarakhand. Specialized habits like cushion or mat forming plants, diminutive and bushy habits, plants with deep penetrating tap root systems, and the presence of thick and silvery hairy indumentums are some of the key adaptations to cold deserts.
