The plate boundaries are the limits of the faunal biodiversity. The species can be endemic, converging or invasive. International Union for Conservation of Nature and Zoological Survey of India are the agencies record and make an action plan to preserve extant/extinct and endangered species. India has 2.4% of the landmass of the globe but accommodating about 7-8% of the total species of the world so a rich biodiversity nation. The country lies at the confluence of the Central zone of Africa, Europe and Malaya region, the biota therefore includes African, European, Eurasian and Mediterranean geographical areas, India has a unique assemblage of flora, fauna, avifauna and aqua-fauna along with some endemic species, that contributes to the richness of the nation. India’s biodiversity population changes are influenced by climate, temperature, altitude, invasive alien species, topography, moisture, CO2, light, nutrients, water quality, ambient air, habitation, and above all the anthropogenic activities for their growth, survival, or reproduction. Present study envisages preparation of an updated bio-geographical status of the species, statistical analysis of the biota those are endangered and threatened and causes for such defaunation and defloration. Though preservation action plans have been enhanced in India through biodiversity reserves yet it is observed that the largely under-explored sector is algae, protists, fungi, microbes. The biodiversity in the marine sector is given less importance for conservation in India.
