Erosion Control Toolbox: Liners and Seedlings
Liners and seedlings work involves planting small perennial or woody shrubs as typically supplied by commercial nurseries. Liners are in containers between 1.5 to 3 inches in diameter and 8 inches in depth. Seedlings are approximately the same size as Liner plants but are a bare root plant without a container.
When to Use This Treatment
Use for disturbed slopes or flat areas for revegetation or erosion control purposes.
- For more reliable revegetation Liners and Seedlings can supplement planting provided by hydroseeding or dry seeding alone
- Vegetation provides long-term control of erosion
- Can be used in areas with limited vehicular access
- Availability must be verified prior to specyfing, as specific plant material may be limited
- Protection from erosion provided only after plant growth has begun
- May require planting during the rainy season or supplemental irrigation for effective plant establishment
