Summary Introduction
Introduction: A forest is the complex of the ecosystem that serves as the home for the world’s terrestrial biosystem. It plays an important role as habitat to various arrays of plants and animals. About 1.8 billion people depend on forests for their livelihood. Depending on the local soil, temperature, and rainfall, they are classified into different types, namely, tropical forest, temperate forest, coniferous forest, deciduous forest, and so on.
