Panaji, July 19 (IANS) Key recommendations of a task force appointed by Prime Minister Manmohan Singh to boost tiger numbers have not been implemented, environmentalist Madhav Gadgil, a former member of the panel, said Tuesday.

Speaking to reporters on the sidelines of a workshop in Panaji, Gadgil said the crucial recommendations made by the five-member task force, led by environmentalist Sunita Narain, were ignored by the central government.

"The task force made recommendations that the management of tiger reserves should be made much more participatory and people-friendly," said Gadgil.

"But the recommendations of the task force are not at all being implemented. I am not happy with the rigid regulatory approach of the forest department," said the Padma Bhushan awardee.

The tiger task force was set up by the prime minister in 2005, following the shocking revelations that tigers had disappeared from the Sariska Tiger Reserve in Rajasthan.

It was asked to recommend long-term actions to boost the numbers of tigers in the country and improve their natural habitat.
