The calculated community benefits, reflected in 2023 U.S. dollars, represent the value of marsh ecosystem services in observable, market-based, quantities. Specifically, dollar amounts related to the benefits associated with: reduced storm impacts, improved fish habitat, reduction/storage of nutrients, reduction/storage of carbon, and improved recreational fishing.
The price of my inputs, added or available, exceeded or will exceed the estimated community benefit value; does that mean that my living shoreline project was/is not worth implementation?
No! Notably, the benefits estimated are distinct from those provided to an individual property owner through private property value. Using this tool, a property owner can estimate the benefits to their property and the surrounding community for a more holistic picture of shoreline value.
This value does not capture all services provided by marshes and living shorelines. For example, non-use and certain non-market values, including aesthetic, historical, moral, emotional and/or spiritual values were not measured and are not reflected in the SHORE-BET calculations. In addition, use values associated with any commercial fishing or recreation other than fishing were not included. Accordingly, the SHORE-BET team acknowledges that the community benefit value calculation is likely an underestimate of a marsh or living shoreline’s total use and non-use value, a consideration decision-makers are asked to keep in mind when reflecting on the outputs of the calculator.
Where can I find details on how estimates were calculated and related rationale?
Detailed calculation descriptions can be found by clicking the “Calculation Info” icon in the bottom right region of the SHORE-BET Tool dashboard.
Can this tool calculate the value of an existing living shoreline or tidal marsh?
Yes! This tool can calculate the value of existing living shorelines and tidal marshes. Benefits are calculated using the parameters of marsh length and width; if these parameters are known, benefits can be calculated.
Why was this tool created?
Using economics to quantify environmental benefits provided to people from nature is one way to assess our environment and the decisions around protection and restoration we make therein. Economics also enables quantification of tradeoffs in monetary units and the accounting of related benefits.
I live/work outside of the Middle Peninsula. Is this tool available for my geography?
The geographic focus of the tool is the counties along the Chesapeake Bay within the Middle Peninsula, Virginia (Gloucester, Mathews, Middlesex); however, the approaches behind the tool can be transferred to other regions.
