Advancing Nature-Based Solutions

An overview of living shorelines and the U.S. Army Corps of Engineers’ proposed permit


Advancing Nature-Based Solutions

In June, the U.S. Army Corps of Engineers proposed a new nationwide permit for living shoreline projects—which typically consist of vegetation combined with native elements such as oyster reefs or rock sills—to combat erosion. These natural bank-stabilization techniques provide a proven and durable alternative to hard infrastructure, such as bulkheads and seawalls, and conserve the coastal habitat of fish and marine life, shorebirds, and plants.

Speakers discussed the latest scientific research on nature-based solutions, the Corps’ efforts to advance the use of natural infrastructure projects, its Nationwide Permit Program, and the proposed living shorelines permit.

Living shorelines foster greater biodiversity than seawalls, according to a recent Pew-supported research project. The study, conducted by Rachel Gittman, Ph.D., postdoctoral researcher at the Northeastern University Marine Science Center, looked at the effects of shoreline protection on coastal ecosystems. Specifically, she compared how many different species (i.e., biodiversity) and individuals of each species (i.e., abundance) were found on seawalls and bulkheads compared with living shorelines. Her article, “Ecological Consequences of Shoreline Hardening: A Meta-analysis,” will soon be published in the journal BioScience.
