Vertical bundle

« Back to Glossary Index

A soil bioengineering technique using bundles of willow cuttings, placed in vertical trenches along an eroding bank. These cutting bundles extend from the streambed to the top of the bank, are covered with soil, and staked into the bank. The bundles will sprout branches and roots that will help stabilize the bank. This technique allows the planting of woody plant materials in areas where digging is difficult or impractical. [Source: USDA National Plant Materials Manual]
