Evergreen forests are an important topic that is included in the UPSC Prelims. Evergreen forests are found on the eastern and western slopes of the Western Ghats in states such as Tamil Nadu, Kerala, Karnataka, and Maharashtra. They are also found in Assam, Arunachal Pradesh, Nagaland, Tripura, Meghalaya, West Bengal and Andaman and Nicobar Islands. The tropical evergreen forests are usually found in areas receiving more than 200 cm of rainfall and having a temperature of 15-30 degrees Celsius. They occupy about 7% of the earth’s surface. They are found mostly near the equator. These forests are dense and multi-layered. They harbour many types of plants and animals. The forests constitute an important part of the environment and ecology. These trees are an important component of the Forest Biology and ecosystem, that helps to promote life in the ecosystem. This allows the plants and animal life to harmonize and live with one another in absolute peace. The evergreen forests are essential in not only promoting greenery on the planet, but they are also useful in the continual survival of animals and plants in the forest ecosystem. There are quite a few different plants and animals that exist in harmony with another for the continual survival of the species. This co-existing system of plants and animals leads to the existence of a biome. A biome is the collection of all wildlife and plants that coexist in a certain environment defined by certain geographical boundaries.
The trees are evergreen as there is no period of drought. They are mostly tall and hardwood. The different types of animals that live in the evergreen forests are usually of a certain type such as indigenous birds like owls, hawks, cardinals and even some mammals such as deers, possums and raccoons. In India, evergreen forests are primarily located in states such as Karnataka and even Kerala. The Western Ghats are the primary location of the evergreen forest. The forests mainly contain trees such as rosewood, mahogany and ebony. This may seem like a lot to remember however we have a introduction for IAS preparation on Environment and Ecology.
