Biological Corridors were first established in 1999 and bestowed as a Gift to the Earth from Bhutan. There were initially 12 corridors with a total coverage of 3,660 km2 connecting all nine of Bhutan’s protected areas. But with the establishment of Wangchuck Centennial National Park in 2008, three corridors were subsumed.
Bhutan’s Corridors represent a bold and innovative vision unsurpassed by any other nation on Earth. Thus, Bhutan can be rightly pointed out as a world leader in attempting to use Corridors as a cost-effective, reliable strategy to conserve meta-populations of wide-ranging species, promote gene flow for all species, and allow species to adapt to climate change.
It has been observed that there are some narrow corridors (sometimes even less than than1 km) which make it scientifically illogical to meet its purpose. Eight of nine corridors run through more than one district, and seven of nine corridors run through more than one Territorial Forest Division making them more vulnerable to human influence.
