Rosewood
Explanation
The vegetation of the Ganga-Brahmaputra plain is primarily dominated by Tropical Deciduous Forests (Monsoon Forests). These forests shed their leaves for about six to eight weeks in dry summer. In contrast, Rosewood is a characteristic species of Tropical Evergreen Forests, which require heavy rainfall and high humidity.
Option Analysis
- Teak: This is a commercially significant timber species belonging to the Tropical Deciduous forests. While more concentrated in central India, it is associated with the deciduous vegetation belt found in parts of the plains.
- Sal: This is a dominant species of the Moist Deciduous forests. It is extensively found in the Terai region along the foothills of the Himalayas and the lower Gangetic plains.
- Peepal: This tree is ubiquitous throughout the Ganga-Brahmaputra plain and is a characteristic species of the Tropical Deciduous vegetation found in the region.
- Rosewood: This is a hardwood tree typical of Tropical Evergreen Forests. These forests are found in areas with annual rainfall exceeding 200 cm, such as the Western Ghats, the island groups (Lakshadweep, Andaman and Nicobar), and the upper hills of the North-Eastern region. It is not typically found in the deciduous belts of the Ganga-Brahmaputra plain.
Key Takeaway: The Ganga-Brahmaputra plain supports Tropical Deciduous flora like Sal, Teak, Peepal, and Bamboo, whereas Rosewood, Ebony, and Mahogany are restricted to Tropical Evergreen regions.
