Reintroduced Chinese alligators now multiplying in the wild

Washington, July 15 (ANI): The Wildlife Conservation Society (WCS) has announced that reintroduced Chinese alligators have started to multiply in the wild in China, which has given them a new chance for survival.

The WCS's Bronx Zoo, in partnership with two other North American parks and the Department of Wildlife Conservation and Management of the State Forestry Administration of China, has successfully reintroduced alligators into the wild that are now multiplying on their own.

The alligator hatchlings-15 in number-are the offspring of a group of alligators that includes animals from the Wildlife Conservation Society's Bronx Zoo.

The baby alligators represent a milestone for the 10-year effort to reintroduce the Chinese alligator on Chongming Island, located at the mouth of China's Yangtze River.

"This is fantastic news," said WCS researcher Dr. John Thorbjarnarson, one of the world's foremost experts on crocodilians and a participant in the project. "The success of this small population suggests that there's hope for bringing the Chinese alligator back to some parts of its former distribution," he added.

Plans to reintroduce Chinese alligators started in 1999 with a survey conducted by WCS, the Anhui Forestry Bureau, and the East China Normal University in Anhui Province, the only remaining location where the reptiles are still found in the wild in what is a small fraction of the alligator's former range.

The results of the survey were dire, with an estimate of fewer than 130 animals in a declining population.

The first three animals released in Hongxing Reserve of Xuancheng County in Anhui in 2003 were from the Anhui Research Center of Chinese Alligator Reproduction (ARCCAR).

To ensure the maximum genetic diversity for the effort, project participants imported 12 more animals to Changxing Yinjiabian Chinese Alligator Nature Reserve from North America, including four from the Bronx Zoo.

From this group, three animals from the US were released in 2007 along with three more alligators from Changxing.

The alligators were given health examinations by veterinary professionals from WCS's Global Health Program and the Shanghai Wildlife Zoo and fitted with radio transmitters for remote monitoring before being released.

Experts reported that the reintroduced alligators successfully hibernated, and then in 2008, bred in the wild.

With a former range that covered a wide watershed area of East China, the Chinese alligator is now listed as "Critically Endangered" on IUCN's Red List of Threatened Species and is the most threatened of the 23 species of crocodilians in the world today. (ANI)
