Durable hard timber
Explanation
The Ganga-Brahmaputra delta supports specialized Littoral and Swamp forests, commonly known as Mangrove forests. The region is famously called the "Sundarbans" due to the dominance of the 'Sundari' tree (Heritiera fomes).
Analysis
- Durable hard timber is correct: The Sundari tree yields durable hard timber. This wood is strong and naturally water-resistant, making it commercially valuable for construction purposes, specifically for boat building and house posts.
- Soft pulp for paper industry is incorrect: Soft pulp for the paper industry is primarily sourced from coniferous trees (such as Pine and Spruce) or Bamboo, rather than the hard wood of mangrove species.
- Latex for rubber production is incorrect: Latex for rubber production is obtained from the Rubber tree (Hevea brasiliensis), which is characteristic of Tropical Evergreen forests.
- Medicinal bark for treating malaria is incorrect: Medicinal bark for treating malaria is obtained from the Cinchona tree, which is typically found in Montane Wet Temperate forests.
Key Takeaway: The Sundari tree is a halophyte characteristic of the Sundarbans, commercially prized for its hard, durable timber used extensively in boat building.
