Detailed Explanation:
✅ Statement 1 – Correct: Sea buckthorn is a soil-binding plant with extensive root systems that effectively control soil erosion and prevent desertification, particularly in fragile Himalayan ecosystems.
❌ Statement 2 – Incorrect: Sea buckthorn is not a source of biodiesel; it is cultivated for its berries, leaves, and medicinal/nutritional products, not biofuel production.
✅ Statement 3 – Correct: The plant has high nutritional value with berries rich in vitamins C, E, carotenoids, and omega fatty acids, and thrives in cold, high-altitude regions like Ladakh and Spiti (-40°C to +40°C tolerance).
❌ Statement 4 – Incorrect: Sea buckthorn is a shrub, not a timber tree; its commercial value lies in fruits, cosmetics, pharmaceuticals, not timber.
