Vegetated Buffers Vegetated buffers play a crucial role in coastal ecosystems , naturally forming a protective barrier between wetland or open water areas and adjacent upland regions . These buffers filter nutrients , trap sediment , and safeguard shorelines from erosion . They can be strategically installed along shorelines to mimic natural landscapes , providing similar benefits while enhancing local wildlife habitats .
Regulations Understanding local , state , or federal regulations is necessary when implementing vegetated buffers to safeguard salt marsh ecosystems . The South Carolina Department of Health and Environmental Control-Office of Ocean and Coastal Resource Management ( SC DHEC-OCRM ) holds authority over critical areas , encompassing coastal waters , tidelands , beaches , and dune systems . Any planned land disturbance within these areas may necessitate a permit from SC DHEC-OCRM , along with approvals from local and federal authorities .
Fortunately , in many cases , establishing vegetative buffers occurs in adjacent upland areas without disturbing critical salt marsh zones . Hence , special permits might not be required . For clarity , this guide focuses on buffer establishment and maintenance actions within the upland area above the highwater mark , thus ensuring compliance with regulations while fortifying coastal resilience .
Site Selection Ideal locations for vegetated buffers are areas without hardened structures , set back from buildings , and along pond and marsh edges . They are particularly beneficial in residential areas with manicured landscapes . Buffer width is recommended between 50-75 feet , but smaller buffers are suitable for limited spaces .
Materials and Design Native plant species resilient to saltwater conditions are preferred . Ornamental grasses and groundcovers are key for runoff interception and soil stabilization , while trees and shrubs promote biodiversity .
Preparation and Installation Site preparation involves removing debris and non-native plants while preserving existing native vegetation . Additional soil can be added without disrupting natural runoff . Plants should be arranged to create a natural layering effect , avoiding excessive elevation changes . Maintenance and Monitoring : Initial irrigation supports plant establishment , gradually reduced over time . Regular weeding , mulching , and pruning are necessary for proper growth and management . Site plans should accommodate plant maturity for long-term effectiveness .
By implementing and maintaining vegetated buffers , coastal communities can enhance resilience , protect shorelines , and promote biodiversity while providing aesthetic benefits for residents .
