What is it?

Vegetated cribbing is a bank stabilization technique used at sites where slope grating and revegetation techniques are not appropriate or provide enough erosion protection. The bank is stabilized using tiered log structures with integrated plant cuttings.

Conservation Benefits

• Promotes bank stabilization and revegetation
• Reduces sediment input into streams

What does it include?

Cross timbers are built into and along the bank to form tiered layers to support a backfill of soil and vegetation plantings. Tiers should follow the contour of the bank and can be as tall on the bank as needed. Extra support can be added to the structure by using cross timbers.
