U.S. Tidal Wetland Carbon Sequestration Priority Maps

NASA's dataset provides geospatial shapefiles identifying tidal wetland parcels in the contiguous U.S. with potential for net greenhouse gas removal through restoration. It maps impounded coastal wetlands, classifying them by current wetland type, restoration category, and estimated carbon dioxide removal potential with uncertainty ranges. The data focuses on managed lands from 2006 to 2011.

Use Cases

• Identifying impounded wetland parcels for tidal flow restoration to reduce methane emissions.
• Prioritizing restoration projects based on estimated mass of carbon dioxide removal potential.
• Analyzing spatial distribution of wetland types and restoration categories along U.S. ocean coasts.
• Incorporating uncertainty estimates into climate solution planning and carbon accounting.

Strengths

• Provides specific estimates for potential greenhouse gas removal in units of mass carbon dioxide.
• Focuses on managed, impounded wetlands where restoration impact is likely highest.
• Includes uncertainty estimates for the carbon removal calculations.
• Cross-platform presence on Data.gov and NASA EarthData indicates institutional importance.

Limitations

• Key technical details like row count, column names, and exact file size are unavailable from all sources.
• There is a conflict in the 'last updated' date: Data.gov lists 2026-03 13, while NASA EarthData lists 2011-12-31.
