Consider the following States: 1) Arunachal Pradesh 2) Himachal Pradesh 3) Mizoram In which of the following states, do “Tropical Wet Evergreen Forests” occur?

The correct answer is C, that is, statements 1 and 3 only. Tropical Wet Evergreen Forests need very high rainfall (generally above 200 cm a year), high humidity and warm temperatures all year, and they are found in the lowland and foothill belts of the Eastern Himalaya, the southern hills of Mizoram, the Western Ghats and the Andaman and Nicobar Islands.

• Statement 1 (Arunachal Pradesh): correct. The eastern and southern lower valleys and foothills of the state have typical wet evergreen patches within the Eastern Himalayan biodiversity zone.
• Statement 2 (Himachal Pradesh): incorrect. Its forests are temperate and subtropical, such as chir pine, deodar and oak, with alpine vegetation at higher elevations. Dry deciduous forests occur in the Shivalik foothills. Tropical wet evergreen forests do not occur here.
• Statement 3 (Mizoram): correct. The southern and western hills of the state, with heavy rainfall, support wet evergreen formations.

The core concept is the forest classification of Champion and Seth, which the NCERT Geography and Environment sections use. For Mains, this links to the Eastern Himalaya and Indo-Burma biodiversity hotspots and to the ecological basis of forest policy in the Northeast.

Trap: Aspirants often assume that every hilly state, or every state in the Northeast, has the same forest type. Himachal's green hills are mostly temperate and subtropical, not tropical.
