Q. Which one of the following regions of India has a combination of mangrove forest, evergreen forest, and deciduous forest?

Answer: (d) Andaman and Nicobar Islands

The epiphytic vegetation, mostly ferns, and orchids are found in South Andaman forests.
Moist deciduous forests are found in the Middle Andamans.
North Andamans is characterized by the wet evergreen type, with plenty of woody climbers.
The North Nicobar Islands (including Car Nicobar and Battimalv) are marked by the complete absence of evergreen forests, while such forests form the dominant vegetation in the central and southern islands of the Nicobar group.
Grasslands occur only in the Nicobars, and while deciduous forests are common in the Andamans.
The present forest coverage is claimed to be 86.2% of the total land area.
This atypical forest coverage is made-up of twelve types namely (1) Giant evergreen forest (2) Andamans tropical evergreen forest (3) Southern hilltop tropical evergreen forest (4) Cane brakes (5) Wet bamboo brakes (6) Andamans semi-evergreen forest (7) Andamans moist deciduous forest (8) Andamans secondary moist deciduous forest (9) Littoral forest (10) Mangrove forest (11) Brackish water mixed forest (12) Submontane hill valley swamp forest.
