The Indian Council of Forestry Research and Education (ICFRE), an autonomous body under the Ministry of Environment, Forest and Climate Change, has its headquarters in Dehradun, Uttarakhand.
Dehradun has long been a major hub for forestry research in India, and it is also home to the Forest Research Institute (FRI).
Mussoorie, Munnar and the Sundarbans are not ICFRE's administrative headquarters, which rules them out.
