Explain scientific forestry?

The first Inspector General of forest in India was a German expert, Dietrich Brandis who was appointed by the British. He set up Indian Forest Service in 1864 and helped formulate the Indian Forest Act of 1865; the Imperial Forest Research Institute was set up at Dehradun in 1906. What taught here came to be known as Scientific forestry.

Under scientific forestry, the different types of trees were cut down in the natural forests. The method of planting one type of tree in straight rows came to be known as Plantation. For the forest management, officials surveyed the forests to estimate the area under different types of trees and created a proper working plan. They also planned how much of the plantation area to be cut every year. Then on the same land, trees replanted so that it becomes ready to cut after some years. All this comes under the Scientific forestry.
