Mention any five features of tropical evergreen forest?
The main Characteristics of tropical evergreen forests are:
i) The trees in this forest do not shed their leaves all together in any season and are therefore known as evergreen forests. These forests are also called Tropical rainforest.
ii) The trees are found in the Western slopes of the Western Ghats covering the states of Western parts of Maharashtra, Karnataka and Kerala. They also occur in The Hills of North East India as well as West Bengal , Orissa and Andaman and Nicobar Islands. Due to the presence of moisture tree growth is very fast.
iii) These forests are found in areas where annual rainfall is more than 200 cms and the mean temperature is more than 20degreeC.
iv) The trees reaches a height of 60 m or more to catch sunshine. The long and broad leaves form a covering at the top known as the canopy. Rain drip slowly from this canopy causing little damage to soil.
v) These forests support a large number of plant species.
e.g Ebony , mahogany, coconut, bamboo, shisam, ferns and Rosewood are typical trees of these forests.

Features of Tropical Evergreen Forest
Tropical evergreen forests are characterized by their dense vegetation, high levels of biodiversity, and year-round warm and humid climate. They are found in regions near the equator, including parts of South America, Africa, and Southeast Asia. Here are the five key features of tropical evergreen forests:
Diversity of Flora and Fauna:
Tropical evergreen forests are known for their incredible diversity of plant and animal species. These forests support an abundance of plant life, including tall trees, epiphytes, lianas, and ferns. The dense canopy of the forest provides a suitable habitat for a variety of animals such as monkeys, birds, reptiles, and insects. The high biodiversity in these forests contributes to their ecological importance and makes them a hotspot for scientific research and conservation efforts.
Continuous Leaf Shedding:
One distinct characteristic of tropical evergreen forests is the continuous leaf shedding that occurs throughout the year. Unlike deciduous forests, where trees shed their leaves during a specific season, evergreen trees in tropical forests shed leaves continuously as part of their natural growth and renewal process. This ensures a constant supply of nutrients to the forest floor, promoting the growth of new vegetation.
Canopy Layering:
The forest canopy in tropical evergreen forests is highly layered, with tall trees forming the uppermost layer. These trees, often reaching heights of 30 meters or more, compete for sunlight and create a dense shade below. The lower layers consist of smaller trees, shrubs, and understory plants that adapt to the limited sunlight that reaches the forest floor. This multi-layered structure of the canopy provides a unique microhabitat for various plant and animal species.
Epiphytic Vegetation:
Tropical evergreen forests are renowned for their epiphytic vegetation, which includes plants such as orchids, bromeliads, and ferns that grow on the trunks and branches of trees. These plants derive their nutrients from air, rain, and debris that accumulate around them, rather than relying on the soil. Epiphytes play an important role in the forest ecosystem by providing additional habitats and food sources for a variety of organisms.
High Rainfall and Humidity:
Tropical evergreen forests receive high levels of rainfall throughout the year, often exceeding 2,000 millimeters annually. The warm and humid climate, combined with regular rainfall, creates ideal conditions for the growth of lush vegetation. The dense foliage of the forest helps retain moisture, further increasing humidity levels. This high moisture content supports the growth of diverse plant species and sustains the forest ecosystem.
In conclusion, tropical evergreen forests are characterized by their rich biodiversity, continuous leaf shedding, layered canopy structure, epiphytic vegetation, and high rainfall and humidity. These features contribute to the unique and vibrant ecosystems found in these forests, making them important areas for conservation and research.
