 In 2007, proposals for declaration of Kodaikanal Wildlife Sanctuary were under consideration of the Government.On August 13, 2012, in an apparent change away from plans for notification of parts of the Palani Hills as a separate wildlife sanctuary, the Tamil Nadu Gazette notification attached parts of Kodaikanal and Dindigul divisions of reserve forests to the buffer zone of Annamalai Tiger Reserve.About 5155.42 hectares of forest land belonging to Palani Hills Northern Slope, Andipatty reserve forest, 4,344.53 acres in Kudraiyar block forest and 5,548.49 hectares in Mannavanur Range in Kodaikanal will be included in the buffer zone.
