NATURAL VEGETATION BY SANYA CHAUHAN

NATURAL VEGETATION &WILDLIFE & CONSERVATION
Natural vegetation refers to a plant community which has grown naturally without human aid and has been left undisturbed by humans for a long time. This is termed as virgin vegetation. Thus, cultivated crops and fruits, orchards form part of vegetation but not natural vegetation.The nature of the plants in an area, to a large extent, determines the animal life in that area. When the vegetation is altered, the animal life also changes. All the plants and animals in an area are interdependent and interrelated to each other in their physical environment, thus, forming an ecosystem. Human beings are also an integral part of the ecosystem. A very large ecosystem on land having distinct types of vegetation and animal life is called a biome. The biomes are identified on the basis of plants.
