Explanation:
Forestry can be defined as the art and science of creating, development, management, conservation and analysis of the living organisms such as plants, trees and woodlands existing in the forest.

Forest Management is a branch of forestry. The field of forest management typically deals with legal, administrative, financial, economical, technical and social aspects of a forest so as to facilitate the smooth running and operation of the forest reserve.
