Willow Spiling

sustainable erosion control

Spiling is the most common method of bank revetment using willow. It involves weaving live willow rods between live willow stakes set into the affected bank at regular intervals.

Willow spiling work is usually carried out between November and April while the willow is dormant.

Within a few months, the willow spiling should achieve a dense top growth and a root mat should be formed.

The root mat provides the bank with added strength to withstand erosion arising from wave action.

Top growth can be allowed to grow to form a screen for the bank or controlled by cutting or grazing if access is required in the future.

There are a few considerations to bear in mind when considering using willow spiling to prevent water erosion:

• Willow will not grow below the late spring/early summer water level - for erosion problems below this level a combined solution may be required. This could include the use of stones or hazel faggots to reduce wave buffeting.
• Willow does not grown well in shade. Existing tress may require coppicing before spiling is carried out.
• The watercourse needs to be large enough so that the willow will not dominate. Using live willow on small streams may not be suitable.
