Biogeographic Zones of India:
For the planning of conservation of biodiversity at the state and national levels, classifications of ecosystems are done based on biogeography. The biogeographical classification uses following four levels of planning:
(1) The Biogeography Zone:
It is a large distinctive unit of similar ecology, biome representation, community and species, e.g., the coasts, the islands, etc.
(2) The Biotic Province:
It is secondary unit within a biogeographic zone, giving weight to particular community.
(3) The Land Region:
It is a tertiary set of units within a province. It indicates different land forms.
(4) The Biome:
It is an ecological unit and is found in biogeographic zones or provinces.Explanation of the Characteristics of Biogeographic Zones of India:
