- covering construction consisting of willow (able to root) and brushwood (not able to root)

- installation and fixation on embankment

- protection against erosion (wind, water)

- intensive and fast rooting; “direct” effects

- use of simple and local available materials

Role of Nature / Mode of Action: 
- imitation/simulation of natural vegetation layers with strong and branched root networks - natural protection against erosion; reduced erosion risk compared to bare hillsides with a high risk of water, wind and soil erosion
Technical & Design Parameters: 
Material for construction: - branches: 2 to 5 years old - commonly used: shrub branches - height: 1,50 m - local and typical plants for the specific location - stake: length: 3 to 5m; diameter: 4 to 8 cm
Conditions for Implementation: 
Good timing for construction, planting is needed (low water flow, no rainfall)
Benefits & Limitations: 
Benefits: - hillside stabilization - protection against erosion - water bank protection - habitat for wildlife
