Should your community prioritize wetland and marsh restoration to reduce the risk of coastal flooding?
The Maryland Department of Natural Resources has launched the Marsh Resilience Portfolio, a new tool designed to assess marsh health and guide conservation efforts. This platform helps land managers prioritize restoration projects to better safeguard coastal communities from flooding and erosion.
Why it matters
By identifying which marshes offer the most protection against coastal risks, the state can more effectively target its restoration resources. This data-driven approach aims to preserve natural barriers against sea-level rise while protecting the state's significant wetland assets.
The new portfolio leverages spatial datasets from the US Geological Survey and wave attenuation metrics from NOAA. It specifically evaluates marsh health, proximity to human populations, and habitat connectivity across the state's vast wetland network.
The players
Maryland Department of Natural Resources
This state agency is responsible for the management, preservation, and protection of Maryland's natural resources and public lands.
US Geological Survey
This federal scientific agency provides impartial information on the health of ecosystems and the environment through extensive mapping and research.
NOAA
The National Oceanic and Atmospheric Administration is a federal scientific agency that monitors oceanic and atmospheric conditions.
The details
Integrated into the existing Maryland Coastal Atlas, the tool uses marsh elevation and vegetation characteristics to generate management recommendations. It serves as a successor to the 2016 Marsh Protection Potential Index, offering enhanced capabilities for selecting sites for living shorelines.
Timeline
The Marsh Protection Potential Index was released in 2016.
The Marsh Resilience Portfolio was released on October 12, 2026.
The Big Picture
The project follows a pattern set by the Maryland Coastal Zone Management Program by utilizing its funding to modernize the state's digital coastal mapping infrastructure. This deployment marks a shift toward leveraging high-resolution spatial data to proactively mitigate the impacts of sea-level rise on critical habitat.
Residents in erosion-prone areas like Dorchester and Somerset counties may see more targeted living shoreline projects in their communities. These initiatives aim to reduce flood risks and improve coastal resilience, potentially mitigating long-term property damage from rising tides.
The takeaway
This tool provides a centralized hub for tracking the health of the Chesapeake Bay's extensive wetland habitats. Property owners and land managers can use this public resource to better understand local vulnerability to erosion and sea-level rise.
