<P> The Government of India Act 1935, which transferred forestry to Provisional list, resulted in abolition of the IFS training . Indian Forest College was established in 1938 . The Superior Forest Service officers, recruited from different states, were trained in the Indian Forest College . The stated mandate of the service was scientific management of the forests to exploit it on a sustained basis for primarily timber products . It was during this time that large tracts of the forest were brought under state control through the process of reservation under the Indian Forest Act, 1927 . </P> <P> The management of the forest went into the hands of the provincial government in 1935 and even today the Forest Departments are managing the forest of the country under the respective State governments . Since the subject of forestry was shifted to the concurrent list in the year 1977, the central government plays an important role, particularly at the policy level in the management of the forest . </P> <P> The main thrust of managing forests for production of timber products as in the British period continued even after the reconstitution of IFS in 1966 . The recommendations of National Commission on Agriculture in 1976 was a landmark shift in forest management . It was for the first time that people's perception was taken care of in addressing biomass needs and extension activities through social forestry were introduced . The concept of sustained yield was addressed in tandem with biomass needs of the people living in and around forest areas . Equal thrust was given to habitat management in protected area and conserving the biodiversity of the land . Today there are over 2700 IFS officers serving in the country, serving in both the 31 Forest Departments in the States and Union Territories and working in various Ministries and institutions both in the State and Central Government . </P> <Table> <Tr> <Td> "</Td> <Td> There is no alternative to this administrative system...The Union will go, you will not have a united India if you do not have good All - India Service which has the independence to speak out its mind, which has sense of security that you will standby your work...If you do not adopt this course, then do not follow the present Constitution .
