News Summary:
  • A decade ago, the presence of Northern river terrapin had declined to “undetectable in the wild” in West Bengal and Odisha.
  • Since than, officials of the Sunderbans Tiger Reserve and experts from Turtle Survival Alliance (TSA), are running a recovery program, through captive conservation breeding.
  • Getting new enclosure for the breeding programme would protect the species against natural risks, and also facilitate genetic management.
  • The Northern river terrapin is set to get a new home – three fresh water ponds in the Sunderbans Tiger Reserve.
  • The turtles will be released with satellite transmitters to determine survival and dispersal.
Turtle Survival Alliance (TSA):
  • It was formed in 2001 as an IUCN partnership for sustainable captive management of freshwater turtles and tortoises.
  • It was formed in response to the Asian Turtle Crisis.
  • Since then it has become a recognised force in turtle and tortoise conservation globally.
