A Novel Monitoring Framework to Assess Intertidal Biodiversity in Mixed Coarse Substrate Habitats Across the Boston Harbor Islands

The Northeast U.S. coast is experiencing some of the fastest rates of sea level rise in the world. The Boston Harbor Islands National Recreation Area is particularly at risk from sea level rise and coastal storm impacts. Erosion and storm impacts have already led to the degradation of shoreline habitats and protective structures (e.g., sea walls), as well as direct impacts to historic landmarks on some islands. The need to establish reliable methods for inventory and monitoring of marine nearshore habitats has emerged out of an effort to use the Boston Harbor Islands as study sites to understand how experimental manipulation of the coastline (e.g., the installation of in-water reefs) might reduce wave energy and erosion and protect [...]
