Comparison of nutrient accrual in constructed living shoreline and natural fringing marshes
نویسندگان
چکیده
Living shoreline marshes are coastal wetlands constructed as alternatives to “hardened shorelines” (e.g., bulkheads, riprap) mitigate erosion and allow for landward migration of intertidal habitat sea level rises. shorelines designed mimic natural fringing over time should be sinks carbon other nutrients. We collected soil cores aboveground plant material from 13 pairs living different ages degree isolation more extensive marsh shorescapes compare nutrient pools accrual. Although the content plants was similar within between types, nutrients were variable both aged 2–16 years long-established marshes. Most—but not all—living had lower organic content, higher bulk density, % carbon, nitrogen phosphorus than their pair. Variation in strongly correlated with either age or estuarine shorescape. Assuming constant accrual individual marshes, we estimated levels would approach those observed paired, timescales less 10 many decades. on trajectories match function respect storage systems.

Living Shorelines: Coastal Resilience with a Blue Carbon Benefit
Living shorelines are a type of estuarine shoreline erosion control that incorporates native vegetation and preserves native habitats. Because they provide the ecosystem services associated with natural coastal wetlands while also increasing shoreline resilience, living shorelines are part of the natural and hybrid infrastructure approach to coastal resiliency. Marshes created as living shoreli...
