Top Biodiversity Hotspots and Forests of Karnataka
Top places of biodiversity importance in the Karnataka state
Karnataka state in India has huge forest reserves. Karnataka Biodiversity Board has joined hands with Karnataka Forest Department to identify and distinguish an area of 100-200 hectares depending upon the availability in the core forest regions of 13 dry land districts. No harvesting is allowed in these areas.
The top 10 places that are rich in biodiversity have been identified just to conserve the nature in its original form. The forests conserved today are very precious for the life of humans and are helpful in maintaining balance in the environment all the time.
The Dry zone biodiversity conservation sites network project has recognized 14 rare, endangered and vulnerable species. The necessary actions like fire protection, sowing of native species, soil and water conservation are taken up in these areas. Inventorization and documentation of biodiversity is done with high priority. This helps in conserving the dry zone forest species which are nearing extinction due to their high medicinal value.
Biodiversity and the life forms
Biodiversity is the measure of different life forms within a given species, ecosystem, biome, or an entire environment in the planet. Biodiversity is the evaluation of the strength to sustain life forms in ecosystems. Biodiversity is in part a function of the type of weather acting over a particular area.
