Month	J	F	M	A	M	J	J	A	S	O	N	D
Average maximum temp °C	31	31	31	31	30	30	29	28	29	29	30	31
Average minimum temp °C	21	21	21	21	21	21	20	20	20	20	20	20
Rainfall (mm)	51	85	188	158	139	121	134	168	185	221	198	86

If this geographic area were to have a natural forest, which one of the following would it most likely be?
1. Moist temperate coniferous forest
2. Mountane subtropical forest
3. Temperate forest
4. Tropical rainforest

Answer 1

Correct Answer - Option 4 : Tropical rainforest

The correct answer is Tropical rainforest.

• Tropical Rainforests:-
  • The tropical rainforest also called evergreen forests usually occur in areas receiving more than 150- 200 cm of rainfall and having a temperature of 15 to 30 degrees Celsius.
  • In India, evergreen forests are found in the western slopes of the Western Ghats in States such as Kerala and Karnataka.
  • They are also found in the hills of Jaintia and Khasi. Some of the trees found in Indian Tropical Forests are rosewood, mahogany, and ebony. Bamboos and reeds are also common.
  •  Major plant species of Tropical rainforests are-
    • Ebony, Mahogany, Rosewood, Rubber, and Chinchona
  • The major animal species of Tropical rainforests are-
    • Elephants, Monkeys, Lemur, Deer. Birds, Bats, Sloths, Snails, etc.
  • This co-existing system of plants and animals leads to the existence of a biome.
  • A biome is the collection of all wildlife and plants that coexist in a certain environment defined by certain geographical boundaries.

• Montane subtropical forests-
  • These types of forests mainly generated in the state of Assam, Nagaland, Mizoram, Meghalaya, Manipur, Arunachal Pradesh, etc.
  • Mountain ranges of Western Ghats are also the abode of these types' forests.
  • Some significant trees of the montane subtropical forest are poonspar, cinnamon, rhododendron, sal, Sandal, laburnum, pomegranate, olive, oleander, etc.
• Temperate Forests- 
  • These types of forests are mainly generated in the Northern middle Himalayas ranges (1801 to 3001 m) and Southern Niligiri higher Mountain ranges.
  • It takes about 201 cm on average annual rainfalls to produce these types of forests.
  • Some significant trees of the montane temperate forest are rhododendrons, ferns, oak, maple, juniper, deodar, chilgoza, etc.
