Thorn Forests and Scrubs

Mountain Forests:

  In mountainous areas, the decrease in temperature with increasing altitude leads to the corresponding change in natural vegetation.

  • The wet temperate type of forests are found between a height of 1000 and 2000 meters. Evergreen broad-leaf tress such as oaks and chestnuts predominate.
  • Between 1500 and 3000 meters, temperate forests containing coniferous trees like pine, deodar, silver fir, spruce and cedar, are found. These forests cover mostly the southern slopes of the Himalayas: places having high altitude in southern and north-east India. At higher elevations, temperate grasslands are common.
  • At high altitudes, generally more than 3600 meters above sea-level, temperate forests and grasslands give way to the Alpine vegetation. Silver fir, junipers, pines and birches are the common trees of these forests.
  • Above Alpine vegetation Alpine grasslands are found. These are used extensively for grazing by nomadic tribes like the Gujjars and the Bakarwals. At higher altitudes, mosses and lichens form part of tundra vegetation.

Q4. Which characteristic is scrub forest?

Ans. The soil of a tropical scrub forest tends to be arid due to the lack of rainfall and prevalence of evaporation. This biome's soil is well-drained, and xeric soils are often found on old alluvial plains. In areas of rocky soils, thorn scrub vegetation proliferates.

Q5. Where are the thorn forest and scrubs found in India?

Ans. Tropical Thorn Forests and Scrubs are the forests found in the North-Western part of the country, including semi-arid areas of Gujarat, Rajasthan, Uttar Pradesh, Chhattisgarh, Haryana, and Madhya Pradesh.
