Often dismissed as worthless "mudflats," coastal wetlands actually generate substantial economic benefits, according to new research from Virginia's Middle Peninsula. A groundbreaking study reveals these ecosystems contribute approximately $90 million in annual net benefits to local communities—equivalent to 3.3% of regional GDP.

Conducted by researchers from William & Mary and the Virginia Institute of Marine Science (VIMS), the study employed scientific methods to quantify wetlands' previously unrecognized economic value. The findings challenge longstanding perceptions about these critical habitats.

To help coastal managers make informed decisions, researchers developed the SHORE-BET tool (Shoreline Habitat Assessment and Restoration Economics – Benefits Estimation Tool). This innovative system evaluates the financial impact of different shoreline management strategies, enabling data-driven conservation policies.

SHORE-BET calculates wetlands' economic contributions across multiple ecosystem services, including:

- Flood prevention and storm protection

- Water filtration and pollution control

- Commercial and recreational fisheries support

- Carbon sequestration and climate regulation

By translating ecological benefits into monetary terms, the tool provides compelling economic justification for wetland preservation. Researchers suggest this approach could reshape public understanding of coastal ecosystems and inform more effective environmental policies.

The study's methodology and SHORE-BET tool are now being considered for broader application, potentially helping coastal communities nationwide balance economic development with environmental protection.
