5.5 Eroding slopes and rocky sites

- Determine whether soil conservation measures such as bounds or contour ridges are necessary. If so, construct them as described in technical sheet 2.
- Use species with a deep, wide-spread root system and good initial growth.
- Restrict weeding to the area around the seedling.
- On severely degraded sites put a tablespoon of complete fertilizer at the bottom of the holes to provide a good start for the seedling.
- If stones are available, surround the plant with small stones.
- Avoid using vehicles that might damage the vegetation and the soil. Rainwater might otherwise wash away soil and cause erosion.
- Do not plant in a regular pattern, the seedlings should always be planted on the best available spot.
- When refilling the plant holes, remove all stones. Extra soil might be needed.
