The Research Wing looks after forestry research in the state. An officer of the rank of Chief Conservator of Forests supervises the work of the Research Circle. The research activities are periodically examined by an Advisory Committee at Directorate Level comprising Principal Chief Conservator of Forests, West Bengal as Chairman; Managing Director of West Bengal Forest Development Corporation, Chief Conservator of Forests (Research &Development), Chief Conservator of Forests (West), Chief Conservator of Forests (North), Chief Conservator of Forest, (Planning & Monitoring) as members & Conservator of Forests, (Research) as member secretary.

The main thrust in the field of forestry in the State is on the improvement of forest trees and productivity of forests. Seed trees and seed stands have been identified and Candidate plus trees have been selected as best individuals for different species. Experiments have been carried out successfully for many species to propagate the best selected trees vegetatively through rooting of cuttings for production of clones.

Progeny tests are being done for number of species with a view to judging critically the genetic quality or otherwise phenotypically selected trees. In addition, attempts are also being made to improve forest quality by introducing plant populations of different species from the source external to the state.

Species introduction trial has been considered as another method of improving the forest quality of the State. In this trial, species exotic to this country are being introduced and propagated in suitable environment and particularly where indigenous species fail to thrive.
