CHENNAI: Forest and tree cover has declined in Tamil Nadu and the State has not prepared its own forest policy even though five years have passed since a recommendation to do this was made by the National Forest Commission, says a report of the Comptroller and Auditor General of India.

The report - released by principal accountant generals Suhasini Srinivasan and S Murugiah at the office of the the Principal Accountant General on Wednesday - states that the state achieved only 22 per cent forest and tree cover against the target of 25 per cent, by 2007.
