Corridors in Asia: recent case studies

Tiger in IndiaFrom the Middle East to Indonesia, recent studies are providing more details about the status of Asian species (particularly mammals), and providing recommendations for how to keep populations connected in increasingly human-dominated regions.

  • Despite increased knowledge about threatened tiger populations in north-western India, a recent project to restore a critical landscape corridor has not helped populations recover.  This is due in part to the failure of the conservation agencies and NGOs in charge to fully understand the political complexity of coordinating local agencies in the region.

Harihar, A., Ghosh-Harihar, M. and MacMillan, D.C. 2017. Losing time for the tiger Panthera tigris: delayed action puts a globally threatened species at risk of local extinction. Oryx: 1-11.

  • Natural regeneration of underproductive or abandoned agricultural patches in lowland tropical forests has the potential to function as corridor habitat and reconnect now isolated populations of endangered elephants in Borneo.

  • Road networks, particularly high-level roads, act as a major barrier to creating corridors that link nature reserves for Asian elephants in tropical southwestern China.

Liu, S., Dong, Y., Cheng, F., Zhang, Y., Hou, X., Dong, S. and Coxixo, A. 2017. Effects of road network on Asian elephant habitat and connectivity between the nature reserves in Xishuangbanna, Southwest China. Journal for Nature Conservation 38: 11-20.

  • The presence of protected areas containing well-connected suitable habitat for grey wolves in northern Pakistan may allow for range expansion in the region.  However, vulnerable movement corridors and human use of natural resources may limit how far wolves can go.

  • The first maps of landscape connectivity for desert carnivores in Iran detail core areas and potential corridors for leopards, cheetahs, caracals, wild cats, sand cats, and grey wolves.  They reveal the importance of protected areas for maintaining suitable habitat as well as the difficulty in connecting them due to dispersal barriers such as roads.
