Erosion Control Toolbox: Liners and Seedlings

Introduction

Liner plants

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.

Benefits

  • 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

Limitations

  • 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
