JAIPUR: Fearing that the Keoladeo National Park may lose its heritage tag, Union minister for forest and environment Jairam Ramesh has shot off a letter to chief minister Ashok Gehlot to take urgent steps before the park dries up completely."As you are aware, availability of water (source, quantum and timing) has remained a serious issue for effective management of Keoladeo National Park and water shortage has been adversely affecting the wetland characteristics of the park," he said in the letter.Vexed over the state government's inaction, Ramesh has said, "While a number of solutions have been considered to address the issue and funds have also been provided by the Planning Commission to the government of Rajasthan for the Goverdhan drain, the situation on the ground remains grim," he noted.Ramesh warned that in case the prevailing situation persists, the park could be listed as a "World Heritage Site in Danger", causing much embarrassment to the country.The bird sanctuary was bestowed the World Heritage Site' tag by Unesco in 1985, recognising it as the most important breeding and feeding ground for an astounding variety of birds in the world. However, it is now facing a severe water crisis prompting the migratory birds to look for alternate sites.Thanks to a good monsoon this year, and a personal initiative by the collector of Bharatpur to get water released from the Pachna dam, the water shorage at the sanctuary was addressed to an extent.The minister has called for a pragmatic solution to the water management issues at the site which is still dependent on the vagaries of monsoon and uncertainties associated with the release of water to the Ajan bund.Experts from the Wildlife Institute of India (WII) in Dehradun had earlier said that if adequate water arrangements are not made in the bird sanctuary by January 2011, there is a strong possibility of the park losing the Unesco recognition.
