Environment & Ecology
Context: Recently 10 Giant Asian Tortoise were soft released into protected area of Intanki National Park in Nagaland for conservation.
About Asian Giant Tortoises (Manouria emys):
- It comprised of two subspecies: Manouria emys phayrei and Manouria emys emys.
- They are the largest tortoises in mainland Asia.
- It is the only tortoise that lays its eggs above ground in a nest, which the female constructs of leaf litter.
Habitat:
- Evergreen Forest, dry evergreen forest including bamboo forest.
- They are native to South Asia found in Bangladesh, India, Indonesia, Malaysia, Myanmar, Thailand and Singapore (Extinct).
- In India, the Nengpui Wildlife Sanctuary, North Cachar Hills and Nongkhyllem Wildlife Sanctuary have wild populations in less disturbed habitats.
Conservation Status:
- IUCN Red List: Critically Endangered
- CITES: Appendix II.
- Wildlife (Protection) Act of 1972: Schedule IV
Threats:
- Over exploitation and unsustainable use for consumption and trade of meat resulted into species on the verge of being extinct.
- Total 507 live specimens in seven shipments are seized from illegal trade during 2000-2015.
- It is threatened by shrinking habitat availability as lowland and mid-elevation evergreen forests are degraded.
- These are lost through logging, clearing for agriculture, forest fires, and hydroelectric dams and reservoirs and associated infrastructure.
- Organised large bamboo-cutting in forests impact the tortoises by removing a prime food resource.
- Ethnic violence is a regional issue, and resettlement sites tend to be located in forest areas.
Conservation Efforts:
- Nagaland and non-profits Turtle Survival Alliance and Wildlife Conservation Society conducted soft release of the juvenile tortoises to rewild the species.
- Soft release: It is a process of gradually releasing captive-raised species into the wild.
- It helps the species to develop site fidelity among released individuals and eventually develop the habit to live in the vicinity of the release closure.
- The Joint Asian Giant Tortoise Recovery Project was started in 2017 with the Nagaland Zoological Park (NZP) and Turtle Survival Alliance (TSA).
- Nagaland zoological park has the highest number of Asian Giant Tortoise with 110 hatching from 13 adults.
- Long term programme includes creating awareness in local communities to make them participate in conservation.
