Deodar: A Valuable Construction Tree from the Western Himalayas

The question asks to identify a valuable tree that primarily grows in the western Himalayas and is known for its use in construction. Let's examine the given options:

Analyzing the Options

• Magnolia: While some Magnolia species are trees, they are generally known more for their flowers and are not primarily associated with the western Himalayas or large-scale construction timber.
• Rhododendron: Rhododendrons are common in the Himalayas and are often large shrubs or trees. However, they are primarily valued for their spectacular flowers and are not typically used as a primary construction material due to wood properties or size.
• Cinchona: This tree is famous as the source of quinine, an anti-malarial drug. It's native to South America and while cultivated elsewhere, it is not primarily known for growing in the western Himalayas or for construction purposes.
• Deodar: The Deodar tree, scientifically known as Cedrus deodara, is a large coniferous tree native to the western Himalayas. It is highly valued for its durable, aromatic, and insect-repellent wood. This makes it an excellent choice for various construction purposes, including building houses, bridges, and temples. It is often referred to as the 'Himalayan Cedar'.

Conclusion

Based on the analysis, the Deodar tree perfectly matches the description of being a valuable tree found mainly in the western Himalayas and widely used in construction.
