Out of the total questions asked from environment a substantial number of questions are asked from Biodiversity hotspots, biosphere reserves and tiger reserves . Students have to prepare this segment really well to tackle any unpredictable questions of the UPSC Prelims Examination. In todays article we will discuss a strategy to prepare such questions for UPSC Prelims Exam point of view.
Before discussing the strategy lets have a look at these terms and understand why these areas are important from exam point of view. Biodiversity is referred to as the variation of plant and animal species in a particular habitat. Biodiversity has an evenness and richness of species of flora and fauna . Biodiversity hotspots are those regions which has high richness of species and endemism . This term was coined by Norman Myres.
On the other hand Biosphere reserves are those protected areas where conservation of plants and animals is carried out. The biosphere reserves also restores the traditional life of the tribals living in that vicinity. Biosphere reserves are aimed at conservation of the biodiversity in that particular area. The Biosphere Reserves are identified by the Man and Biosphere Reserve Program to promote sustainable development. This program was initiated by UNESCO in 1971. The Man and Biosphere Reserve Program recognize such areas which have following characteristics
There are three zones in biosphere reserves :
A Tiger Reserve is a 'Core' or 'Critical Tiger Habitat', which is to be managed as an inviolate area, and a 'Buffer' or Peripheral area immediately abutting a Core area, which may be accorded a lesser degree of habitat protection. This is the typical zonation of a Tiger Reserve.
How to Prepare :
India is famous for its rich biodiversity and has around 24.46% of the geographical area covered by forests and trees.

Increased poaching and cutting down trees has resulted into loss of habitat for various plant and animal species. Due to this most of the animal species have reached to status of critically endangered, vulnerable and lost.
