RAS question
Which type of forest covers the maximum area in India?
Correct answer: (A) Tropical deciduous.
Tropical deciduous forests cover the maximum forest area in India, because the moist and dry deciduous groups together account for the largest share of the country's mapped forest-type area.
Explanation
Tropical deciduous forests, also called monsoon forests, are the correct answer because the official FSI forest-type mapping separates them into tropical moist deciduous and tropical dry deciduous groups. In ISFR 2019 Table 4.1, tropical moist deciduous forests account for 17.65% of the grand total, while tropical dry deciduous forests account for 40.86%. Read together as tropical deciduous forests, they form the dominant forest category. Deciduous forests cover about 65% of India's total forest area and are divided by rainfall into moist deciduous, associated with 100-200 cm rainfall, and dry deciduous, associated with 70-100 cm rainfall.
Why the other options are wrong
- (B) Mangrove forests are not the largest category: ISFR 2019 reports India's mangrove cover as only 4,975 sq km, and mangroves are the smallest-area option here.
- (C) Montane forests are limited to hilly and higher-zone settings, whereas the FSI table shows the deciduous groups occupying far larger shares of mapped forest-type area.
- (D) Tropical evergreen forests cover a smaller area: ISFR 2019 lists tropical wet evergreen forests at 2.61% and tropical semi-evergreen forests at 9.27%, below the combined deciduous share.
Concept
This tests India's natural vegetation classification, especially the area-wise distribution of forest types. It recurs in RAS because Rajasthan geography questions often compare forest types by climate, rainfall and spatial extent.
