The correct option is Tendu.
Explanation
Natural vegetation in India is classified based on climatic conditions, specifically rainfall and temperature. Tropical Evergreen Forests require high rainfall (above 200 cm) and high humidity, whereas Tropical Deciduous Forests are found in regions with moderate rainfall (70-200 cm).
Species Analysis:
- Rosewood, Aini, and Ebony: These are commercially important hardwood species characteristic of Tropical Evergreen Forests. These forests are dense, multi-layered, and retain their green appearance throughout the year because there is no fixed time for trees to shed leaves. They are primarily found in the Western Ghats, the island groups of Lakshadweep and Andaman & Nicobar, and the upper parts of Assam.
- Tendu: This species is characteristic of Tropical Deciduous Forests (specifically Dry Deciduous). Tendu trees shed their leaves during the dry season to conserve moisture. Tendu leaves are economically significant as they are widely used in the bidi-rolling industry.
Key Takeaway:
Rosewood, Mahogany, Aini, and Ebony are key species of Tropical Evergreen Forests, while Tendu, Teak, and Sal are dominant species of Tropical Deciduous Forests.
