Question

Into how many categories forests are classified according to their density?
A. 2
B. 3
C. 4
D. 5

Answer 1

Hint: The classification is done on the basis of internationally adopted norms of classification. Mangroves have been separately categorised due to their unique ecological functions.

Complete Answer:
The forests are broadly classified into 4 categories according to their density. The categories are:
1. Very dense forest: All Lands with tree cover (Including mangrove cover) having a canopy density in the range of 70% and above.
2. Moderately dense forest: All lands with tree cover (Including mangrove cover) having a canopy density in the range of 40% and 70% above.
3. Open forest: All lands with tree cover (Including mangrove cover) having a canopy density in the range of 10% and 40%.
4. Mangrove

The classification of the cover into dense and open forests is done on the basis of internationally adopted norms of classification. Owing to the enormity of work of ground validation and limitations of the methodology, it has not been possible to further segregate the dense forest into more classes. Mangroves have been separately categorised due to their typical tone and texture and unique ecological functions.

Hence the correct answer is option (C) 4.

Note: The forest cover mapping of the country is assessed on a two-year cycle by the Forest Survey of India. The main aim is to present the information about the forest resources of the country at the state and district level and to prepare forest cover maps on 1:50,000 scale. In 1987, the first assessment of forest cover of the country was made and from then onwards eight more assessments have been made.
