This can be measured by counting the number of taxa (distinct groups of organisms) within the ecosystem (eg. This involves comparing the number of taxa that are unique to each of the ecosystems. It is the rate of change in species composition across habitats or among communities. It gives a quantitative measure of diversity of communities that experience changing environments. It is the product of the diversity of component ecosystems and the diversity between component ecosystems. Gamma diversity can be expressed in terms of the species richness of component communities as follows: S1 S 2 c where, S1 the total number of species recorded in the first community, S2 the total number of species recorded in the second community, c the number of species common to both communities.

Recently 9 more biodiversity hotspots has been added which makes the present number to 34. To qualify as a biodiversity hotspot on Myers 2000 edition of the hotspot-map, a region must meet two strict criteria:1. It must contain at least 0.5 or 1,500 species of plants of the world.2. It has to have lost at least 70 of its primary vegetation. It has 47,000 species of plants and 81,000 species of animals. At least 325 globally threatened species occur. Eastern Himalayas -: Numerous large birds and mammals, including vultures, tigers, elephants, rhinos and wild water buffalo. Rare species:These are species with small total population size in the world,their distribution are usually localized within restricted area of world. Threatened species: decline in number significantly in total numbers and may be on verge of extinction in certain localities. Identification and documentation of endangered species. Developing awareness about the importance of threatened biodiversity. Defining conservation priorities at the local level and guiding conservation action.
