INTRODUCTION;
Forests are complex ecosystems which show maximum diversity in biotic and abiotic components. A forest performs vital environmental services such as cleansing the air, moderating the climate, filtering water, cycling nutrients, providing habitat for wild life etc. Forest Resources are one of the richest Natural Resources of the Globe. They include animate resources like plant, animal and microbes and inanimate resources like timber produce and non timber produce which can affect the state, regional and national economies. Most of the resources have already been lost and the remainder is being depleted at a rapid rate. The main reasons for degradation of forest are deforestation, habitat loss, over-exploitation, invasion etc. Hence U.N.O. declared 2011 as International Year of Forests in order to draw the attention of the people in the protection and conservation of forests.
