Passage

Ecological -research over the last quarter of the century has established the deleterious effects of
habitat fragmentation due to mining, highways and such other intrusions on forests. When a large
block of forests gets fragmented into smaller bits, the edges of all these bits come into contact with
human activities resulting in the degradation of the entire forests. 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.
