Concept:Conservation:Conservation preserves the ecological diversity and our life support systems €œ water, air and soil.It also preserves the genetic diversity of plants and animals for better growth of species and breeding.So biodiversity conservation is a type of protection and management technique for biodiversity so we can gain sustainable development from resources.Explanation:Endemic species:Endemic species are those species of plants and animals which are found exclusively in a particular area.They are not naturally found anywhere else.A particular type of animal or plant may be endemic to a zone, a state or a country.Examples of the endemic species are-Wild Mango endemic flora of the Pachmarhi Biosphere Reserve.Bison, Indian giant squirrel and flying squirrel are endemic fauna of this area.The destruction of their habitat, increasing population and introduction of new species may affect the natural habitat of endemic species and endanger their existence.Thus, endemic species are species found in a particular area.Additional InformationRare Species:Specie with small populations that may move into the endangered or vulnerable category if the negative factors affecting them continue to operate is called rare specie.Examples of such species are the Himalayan brown bear, wild Asiatic buffalo, desert fox and hornbill, etc.Endangered species:These are the species which are in danger of extinction.Animals whose numbers are diminishing to a level that they might face extinction are known as endangered animals.The survival of such species is difficult if the negative factors that have led to a decline in their population continue to operate.Examples of such species are blackbuck, crocodile, Indian wild ass, Indian rhino, and lion-tailed macaque.Imported species:An invasive species or imported species is a non-native species that spread from a point of introduction to invade and negatively affect a new ecosystem.They're normally introduced for good reasons, yet they can cause environmental, ecological, and economic harm.They are a severe threat to the economy, society, and environment.As a result, they must be thoroughly researched and handled in the long run.
