Continuity of forested landscapes and corridors gets disrupted 'affecting several extinction-prone species of wildlife. Habitat fragmentation, is therefore considered as the most serious threat to biodiversity conservation. Ad hoc grants of forest lands to mining companies coupled with rampant, illegal mining is aggravating this threat.
