UPSC CAPF AC 2017 Paper

Wet evergreen forests are found in the South along the Western Ghats and the Nicobar and Andaman Islands and all along the North-eastern region. It is characterised by tall, straight evergreen trees that have a buttressed trunk or root on three sides like a tripod that helps to keep a tree upright during a storm. Rainfall peaks around 400 mm, but on the average is above 250 mm. The average annual temperature lies in the range of 25-27°. The more common trees that are found here are the jackfruit, betel nut palm, jamun, mango, and hollock. The trees in this forest form a tier pattern: shrubs cover the layer closer to the ground, followed by the short structured trees and then the tall variety. High humidity levels of more than 75% ensures that leaves do not shed leaves throughout the year. Beautiful fern of various colours and different varieties of orchids grow on the trunks of the trees.
