Forests have perennial trees of Sal, Sheesham, Teak, Banyan, Neem, Peepal, Bamboo, etc.

A forest has annual, biennial and perennial plants. Herbs are mostly annuals with a life span of one year. Biennials have a life span of two years whereas perennials can survive for several years. These include shrubs and trees.

The trees produce enough seeds and the forest floor provides favourable conditions for them to germinate and develop into seedlings.

The trees in the forests are of different shapes and heights. The branching part of the tree above the stem is called its crown. It is formed of branches and leaves. These crowns are of different types and sizes and form horizontal layers in the forests. The trees that are not as tall as canopy trees, form different layers or tiers under the canopy are called understoreys.
