These forests grow in regions with more than 200 cm of annual rainfall, a very short dry season, and have trees reaching up to 60 metres or more. They are mainly found in the Western Ghats, Andaman & Nicobar Islands, Lakshadweep, upper Assam, and along the Tamil Nadu coast. Which type of forest is being described?

Answer

Tropical evergreen forests

Why?

The correct answer is Tropical evergreen forests . Key Points Tropical evergreen forests are restricted to heavy rainfall areas typically exceeding 200 cm annually , coupled with a very short dry season. The vegetation is luxuriant and displays a multilayered structure including trees, shrubs, and creepers, with dominant trees reaching heights of 60 metres or more. These forests are predominantly located in the Western Ghats , the island groups of Lakshadweep and Andaman and Nicobar , upper parts of Assam , and along the Tamil Nadu coast . Because there is no specific period for trees to shed their leaves simultaneously, these forests appear vibrant green throughout the year. Commonly found commercial species in these biomes include Ebony , Mahogany , Rosewood , Rubber , and Cinchona . The fauna of these regions often includes elephants , monkeys , lemurs , and the one-horned rhinoceros in the jungles of Assam and West Bengal. Additional Information Tropical deciduous forests : Commonly known as monsoon forests , they are the most widespread forest type in India . They exist in regions receiving rainfall between 70 cm and 200 cm and are subdivided into Moist and Dry deciduous categories. Montane forests : These occur in mountainous regions where temperature decreases with increasing altitude, leading to distinct vegetation belts. Examples include wet temperate forests found between 1000 and 2000 metres and alpine vegetation at altitudes above 3600 metres. Mangrove forests : Located in coastal areas influenced by tides , where mud and silt accumulate. The Sundarbans in the Ganga-Brahmaputra delta is the largest mangrove area, famous for the Sundari trees and the Royal Bengal Tiger .
