Living shorelines

Living shorelines use natural materials and coastal habitats to stabilize sheltered shores while supporting wildlife, cleaner water, and resilience.

Core idea
Living shorelines stabilize shorelines with natural elements such as plants, sand, rock, oyster shells, and reefs.
Best fit
They are usually suited to sheltered coasts, bays, estuaries, tidal rivers, and other lower-energy shorelines.
Added value
Unlike many hard structures, living shorelines can provide habitat, filter runoff, store carbon, and grow more stable over time.

What living shorelines are

A living shoreline is a nature-based approach to stabilizing a shore and reducing erosion. It uses living or natural materials such as marsh plants, sand, coir logs, oyster shells, reefs, rock, or planted slopes instead of relying only on concrete or steel.

How they reduce erosion

Vegetation, reefs, and shallow features slow waves and currents before they reach the bank. Roots help hold soil, shells and reefs break wave energy, and added sediment can rebuild a gentler shoreline profile.

Green to gray spectrum

Shoreline stabilization choices range from soft planted marshes to hybrid designs with stone sills or oyster reefs, and then to hard seawalls or bulkheads. The best choice depends on wave energy, tides, slope, sediment, and nearby infrastructure.

Habitat benefits

Living shorelines can create marsh edge, oyster reef, shallow water, and riparian habitat. These areas may support fish, crabs, shellfish, birds, pollinators, and other species that are often excluded by vertical hard structures.

Water and carbon benefits

Plants, soils, and shellfish reefs can filter runoff, trap sediment, cycle nutrients, and store carbon in coastal wetlands. These benefits depend on site design, plant survival, water quality, and long-term maintenance.

Where they work

Living shorelines are most common along estuaries, bays, tidal creeks, rivers, and protected shorelines. High-energy open-ocean beaches, very steep banks, heavy boat wakes, or deep water may require hybrid or different approaches.

Planning and maintenance

Projects usually need site analysis, permits, planting plans, construction timing, erosion-control details, and monitoring. Maintenance can include replanting, debris removal, checking oyster or rock structures, and repairing storm damage.

Why it matters

Living shorelines turn erosion control into habitat and resilience work. They can help communities protect property while keeping the shoreline connected to marshes, estuaries, fisheries, cleaner water, and future coastal adaptation.
