Biotechnical treatments are an increasingly popular tool used in habitat restoration projects involving riparian bank stabilization and hillside slope erosion control. These treatments incorporate horticulture, biology, physical science, and engineering to create sustainable solutions offering short and long-term benefits for ecosystem restorations.
John Zanzi, a landscape architect with Habitat Restoration Sciences, Inc., discusses key elements to successful implementation in this Biotechnical Treatments White Paper.
Projects using biotechnical treatments are often driven by regulatory requirements for water quality improvement or mitigation for habitat impacts. These projects can stabilize creek banks or hill slopes, slow run-off and encourage infiltration, provide source and intermediate controls for sedimentation, intercept rain drops, control overland sheet flow characteristics, and manage other forces that encourage erosion.
