Guidelines for Installing Buffers

Guidelines for Installing Buffers

• If possible let natural succession take the lead and adjust from there.

• Handle erosion forces with bio-engineering techniques, when applicable.

• Minimize ground disturbance, preserve existing root mass.

• Select plants based upon plant community models.

Cylindrical structures composted of coconut husk fibers bound together with twine woven from coconut material to protect slopes from erosion while trapping sediment which encourages plant growth within the fiber roll.

Coconut Fiber Rolls

Alternating layers of plantings and compacted soil with natural or synthetic geo-textile materials wrapped around each soil lift to rebuild and vegetate eroded shoreline. This may be used in conjunction with stone armoring.

Maintenance Guidelines

Maintenance Guidelines

• Select desired succession level and manage accordingly• Keep undesirable trees and shrubs minimized by cut and paint• No fertilizers or sprayed herbicides if possible
