The correct answer is A. Dehradun.
The Forest Survey of India (FSI) is a national organization engaged in forest cover mapping, forest inventory and training in the field of remote sensing and GIS. It is headquartered in Dehradun, Uttarakhand, India.
The FSI was established in 1981 by the Ministry of Environment and Forests, Government of India. It is a statutory body under the Indian Forest Act, 1927.
The FSI’s main objective is to provide accurate and timely information on the status of forests in India. It does this by conducting forest cover surveys, forest inventory, and training in the field of remote sensing and GIS.
The FSI’s forest cover surveys are conducted every two years. The latest survey was conducted in 2017. The survey results show that India’s forest cover is 21.67% of the total land area.
The FSI’s forest inventory is conducted every five years. The latest inventory was conducted in 2015. The inventory results show that India has 2,264 million cubic meters of standing forest stock.
The FSI also provides training in the field of remote sensing and GIS. The training is offered to government officials, forest officers, and other interested parties.
The FSI is a valuable resource for information on the status of forests in India. Its forest cover surveys, forest inventory, and training programs are essential for the management and conservation of India’s forests.
