Statement by statement
1. It helps in controlling soil erosion and preventing desertification — Correct
Sea buckthorn has an extensive root system that binds the soil.
It is also a nitrogen-fixing plant, which helps improve degraded and fragile ecosystems in cold desert regions.
2. It is a rich source of biodiesel — Incorrect
Sea buckthorn is not considered a major or rich source of biodiesel.
Do not confuse this with plants like Jatropha or Pongamia, which are more commonly associated with biodiesel production.
3. It has nutritional value and is well-adapted to live in cold areas of high altitudes — Correct
Sea buckthorn grows well in extremely cold, high-altitude areas.
Its berries are rich in Vitamin C, Vitamin E, omega fatty acids and antioxidants, making it nutritionally valuable.
4. Its timber is of great commercial value — Incorrect
Sea buckthorn is a small, thorny shrub and does not produce commercially valuable timber.
This is not the defining feature of the plant.
