Ans: The term "natural vegetation" refers to plants that have not been cultivated by humans. Temperature and moisture play a role in plant development. It also depends on parameters such as slope and soil thickness. It refers to grasses, bushes, and trees that develop naturally without human intervention or assistance. Other commercially significant species include bamboos, sal, shisham, sandalwood, khair, kusum, arjun, and mulberry. The reduction in temperature with increasing altitude causes a shift in natural vegetation in mountainous locations.
