Study Notes

Alpine Forests and Vegetation

  • Common trees in Alpine forests include spruce, fir, and pine, adapted to harsh weather conditions.
  • Alpine grasslands are extensively used by nomadic tribes such as the Gujjars and Bakarwals for grazing livestock.
  • At higher altitudes, vegetation shifts to mosses and lichens, which thrive in cold, moist conditions.

Fauna in Eco-Regions

  • Famous animals in mangrove tidal forests include the Bengal tiger, which often thrives in these unique ecosystems.
  • Common animals in Alpine forests consist of snow leopards, ibex, and various bird species like the golden eagle.

Vegetation in Arid Regions

  • Regions with less than 70 cm of rainfall typically feature xerophytic vegetation, such as cacti and drought-resistant shrubs.
  • Trees in thorn forests adapt to arid conditions through features like waxy coatings, deep roots, and reduced leaf surface area.

Thorn Forests and Scrubs

  • Main plant species in thorn forests include acacia, baobab, and other drought-resistant trees, adapting to low moisture availability.
  • Scrub vegetation often comprises tough, drought-resistant bushes that can survive extreme temperatures and dryness.

Forests in Mountainous Areas

  • Common forests found between 1000 and 2000 meters in mountainous areas are temperate deciduous forests, characterized by a variety of broadleaf trees.
  • Forests between 1500 and 3000 meters typically consist of coniferous forests, including species like spruce and fir, adapted to cooler temperatures and harsher climates.
