The British Colonial Government started commercial forestry in India due to following reasons
(i) By the early 19th century, oak forests in England were disappearing. The colonial government needed timber supply for the Royal navy and railways which were essential for the movement of imperial troops and commercial trade.
(ii) The Colonial Government took over the forests in India and gave vast areas to European planters at cheap rates. These areas were enclosed and planted with tea and coffee.
(iii) The British government was worried about the reckless use of forests by the local people. They needed trees that could provide hard wood and were tall and straight. So particular species like teak and sal trees were promoted by them. Thus, commercial forestry was started by the Britishers and Indian forests Act was passed in 1865.
