BNHS supports scientific human intervention in conservation

Highlights Chinese Crested Tern’s success story

Oct 09, 2013 06:10 IST India Infoline News Service

BNHS India has always been advocating human intervention based on scientific research combined with people’s participation to ensure effective conservation of the remaining wildlife and wilderness areas. While the latest list by International Union for Conservation of Nature (IUCN) includes 15 bird species from India as Critically Endangered, there are examples such as Spot-billed Pelican whose condition has improved due to such interventions. The success story of Chinese Crested Tern is also an interesting case study.
 

Conservation through Research and Community Participation
All the threatened bird species on the IUCN list, including the Critically Endangered species as well as their habitats require immediate attention and conservation action. Most of these species are declining drastically in terms of numbers and distribution range and many are now on the verge of extinction. However, when appropriate conservation action is taken, based on science and with the involvement of local communities, several other species have bounced back.
 
For instance, the Spot-billed Pelican, which was earlier categorized as Vulnerable, is now better off and regarded as Near Threatened. The improvement has been primarily because of protection provided to its breeding sites, not just by the forest department, but also by the local villagers. Such examples of community participation in conservation can be observed across India from Khonoma Conservation Reserve in Nagaland to the hornbill habitats in horticultural landscape of Konkan in Maharashtra and the bird congregations in Kheechan in Rajasthan.
 

Chinese Crested Tern
International studies have shown that until this year, there were only two known breeding colonies of the Critically Endangered Chinese Crested Tern; viz. Mazu Islands off the coast of Fujian and Wuzhishan Islands off Zhejiang in China. However, this summer an innovative tern colony restoration project has led to the establishment of one more habitat for the bird. Interestingly, this comes as a welcome change in the otherwise devastated Chinese landscape comprising polluted rivers, deforested mountains and increasing urbanization in the quest for quick GDP growth!
 
Earlier this year, a small island called Tiedun Dao in Jiushan Islands – an archipelago where Chinese Crested Terns used to breed – was chosen for colony restoration. The restoration team consisting of local authorities and experts used decoys and playback tern calls to initially attract the birds. Much earlier than expected, a substantial new colony of over 2,600 Great Crested Terns and 19 Chinese Crested Terns soon took shape on the island, including 600 fledglings of the former and at least one fledgling of the latter. International experts, including those from BirdLife International, observed that this was the highest single count of Chinese Crested Terns since the species’ rediscovery in 2000.
 
Commenting on the re-colonization initiative, Dr Asad Rahmani, Director, BNHS India (which is the BirdLife partner in India), said, “This is good news. Strong conservation action, based on science is also required for species such as Great Indian Bustard, Bengal Florican and Black-breasted Parrotbill. Actions should be species and site specific since problems vary across geographical regions.”
