(16) Environmental laws should be strictly followed. Conservation Methods: There are two types of conservation methods namely in-situ and ex-situ conservations. Let us discuss the different conservation methods along with their importance. (a) In situ conservation: The conservation of species in their natural habitat or natural ecosystem is known as in situ conservation. In the process, the natural surrounding or ecosystem is protected and maintained so that all the constituent species (known or unknown) are conserved and benefited. The factors which are detrimental to the existence of species concerned are eliminated by suitable mechanism. The different advantages of in situ conservation are as follows: (a) If is a cheap and convenient way of conserving biological diversity. (b) It offers a way to preserve a large number of organisms simultaneously, known or unknown to us. (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 …show more content…

Protected areas: The protected areas are biogeographical areas where biological diversity along with natural and cultural resources are protected, maintained and managed through legal and administrative measures. The demarcation of biodiversity in each area is determined on the basis of climatic and physiological conditions. In these areas, hunting, firewood collection, timber harvesting etc. are prohibited so that the wild plants and animals can grow and multiply freely without any hindrance. 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. Protected areas include national parks, sanctuaries and biosphere reserves. There are 37,000 protected areas throughout the world. As per World Conservation Monitoring Centre, India has 581 protected areas, national parks and sanctuaries. 2. National parks: These are the small reserves meant for the protection of wild life and their natural habitats. These are maintained by government. The area of national parks ranges between 0.04 to 3162 km. The boundaries are well demarcated and
