Natural vegetation refers to plant life that grows naturally in an area without human interference. Its distribution depends mainly on climate, soil, and relief. Areas with high rainfall and fertile soil support dense forests, while regions with moderate rainfall support grasslands. Dry regions with poor soils have sparse vegetation like thorny bushes. Cold regions support limited vegetation such as mosses and lichens. Therefore, natural vegetation changes from place to place according to environmental conditions, especially soil quality and climatic factors.
