In this method of biological diversity conservation, sampling, shifting, storage and preservation of target taxa is carried out outside the natural habitat of the organisms. In-situ methods use conservation areas as "warehouses" of biological information. (c) The existence in natural ecosystem provides opportunity to the living organisms to adjust to differed’ environmental conditions and to evolve in to a better life form. Biodiversity is being depleted by the loss of habitat, fragmentation of habitat, over exploitation of resources, human sponsored ecosystems, climatic changes, pollution invasive exotic spices, diseases, shifting cultivation, poaching of wild life etc. The protection and management of biodiversity through in situ conservation involve certain specific areas known as protected areas which include national parks, Sanctuaries and Biosphere reserves. (11) Priority should be given in wildlife conservation programme to endangered species over vulnerable species and to vulnerable species over rare species. Ex-situ conservation: This method refers to the conservation of biodiversity in the areas outside their natural habitat such as zoos and botanical gardens. Another way to prevent getting this page in the future is to use Privacy Pass. That is, the conservation of selected plants and animals in se­lected areas outside their natural habitat is known as ex-situ con­servation. Ex-situ Conservation is one of the primary objectives of Botanical Survey of India (BSI). There are 37,000 protected areas throughout the world.

For example, the landscapes like grass lands, deserts, mountains etc. The diversity may be interspecific (within species) and interspecific (in between the species) but these are well supported by ecosystem. The richness of a species tells about the extent of biodiversity of a site and provides a means for comparing different sites.

In other words, biodiversity is the occurrence of different types of ecosystems, different species of organisms with the whole range of their variants and genes adapted to different climates, environments along with their interactions and processes. Class 8. Biodiversity may be defined as the variety and variability of living organisms and the ecological complexes in which they exist. (iv) It has 10 different biogeographical regions and 25 biotic provinces having varieties of lands and species. In recent years ex situ conservation has advanced beyond keeping threatened species. The in situ conservation method is the protection and maintenance of species populations in the ecosystem in which they occur. The stresses on living organisms due to competition for food, water, space etc. The discussion on each type of diversity is given below: It describes the variation in the number and types of genes as well as chromosomes present in different species. The factors which are detrimental to the existence of species concerned are eliminated by suitable mechanism. Some protected areas are: Cold desert (Ladakh and Spiti), Hot desert (Thar), Saline Swampy area (Sunderban and Rann of Kutch), Tropical moist deciduous forest (Western Ghats and north East) etc. The in-situ concept is best understood in contrast to ex-situ conservation. It describes the assemblage and Interaction of spices living together and the physical environment a given area.
