This new study synthesizes information on the use of living shorelines for shoreline protection and as habitat conservation strategies along eroding shorelines
Globally, shoreline protection approaches are evolving towards the incorporation of natural and
nature-based features (living shorelines henceforth) as a preferred alternative to shoreline
armoring. Emerging research suggests that living shorelines may be a viable approach to conserving
coastal habitats (marshes, beaches, shallows, seagrasses) along eroding shorelines. Living
shorelines typically involve the use of coastal habitats, such as wetlands, that have a natural
capacity to stabilize the shore, restore or conserve habitat, and maintain coastal processes. They
provide stability while still being dynamic components of the ecosystem, but due to their dynamic
nature, careful designs and some maintenance will be required if habitat conservation is a goal.
Living shorelines may represent a singular opportunity for habitat conservation in urban and
developing estuaries because of their value to society as a shoreline protection approach and
resilience to sea level rise. However, enhanced public acceptance and coordination among regulatory
and advisory authorities will be essential to expand their use. To fully understand their
significance as habitat conservation strategies, systematic and standardized monitoring at both
regional and national scales is vital to evaluate the evolution, persistence, and maximum achievable
functionality (e.g., ecosystem service provision) of living shoreline habitats.
