The subtropical dry evergreen forests are found in the western Himalayas, the Bhabar, and the Shiwaliks up to 1000 meters above sea level.

  • Found in the Bhabar, the Shiwaliks and the western Himalayas up to about 1000 metres above sea level.
Climatic Conditions
  • The average annual rainfall is only 800 millimeters.
  • The majority of the precipitation falls between October and December, during the brief northeast monsoon.
  • During the extended dry seasonhigh temperatures can reach a scorching 44°C or higher.
  • The amount of yearly rainfall generally decreases from east to west along the front of the Siwaliks range.
  • Low scrub forest with small evergreen stunted trees and shrubs.
  • Olive, acacia modesta and pistacia are the most predominant species.
  • The flora and fauna of the ecoregion have adapted to the hot, dry climate.
  • The trees’ roots and stems have expanded, storing water for use during the dry season.
  • Water loss is prevented by thick, waxy coatings on the leaves.
  • The original vegetation’s larger, emergent trees have mostly vanished.
  • Thus there are only forests with a shrubby, closed-canopy forest structure that rarely exceeds 10 meters in height.
  • Animals too have developed techniques to survive in the absence of water.
  • The chinkara, sometimes known as the Indian gazelle, can survive for long periods of time without drinking water, surviving on dew and water from the plants it eats.
  • Many smaller species, such as frogs and insects, hibernate in the mud during the dry season.
  • Carnivores like the wild dog, sloth bear, common leopard, and jungle cat prey on herbivores like blackbuck, chinkara, and little Indian chevrotain or mouse deer, among others.
  • Transitional forest ecosystems such as scrub and thorn woodlands are frequently created because subtropical dry evergreen forests have a wide climatic range.
  • They provide valuable timber and thereby boost the employment generation directly and indirectly..
  • Subtropical Dry Evergreen Forest has a rich and diverse fauna and flora.
  • They’re also essential in terms of carbon storage.
  • They have the ability to store large amounts of carbon in their biomass and soils.
