Modeling the past to predict the future: forecasting the relative role of climate change and habitat management on Chesapeake Bay SAV

This project, conducted by the Virginia Institute of Marine Science and supported by a diverse group of steering committee members, modeled the impact of climate change on Chesapeake Bay SAV. The final report, PNAS article, and link to an associated Shiny App that predicts Bay-wide SAV as well as salinity zone and segment-specific SAV, are hyperlinked below. This work was funded through the Chesapeake Bay Program Goal Implementation Team (GIT) Funding Program.

Chesapeake Bay SAV Restoration Manual and Outreach Materials

The below resources, developed by Green Fin Studios in partnership with the SAV Workgroup, include a Chesapeake Bay SAV Restoration Manual and accompanying outreach materials. This work was funded through the Chesapeake Bay Program Goal Implementation Team (GIT) Funding Program.

Tributary Specific SAV Fact Sheets

The Chesapeake Bay Submerged Aquatic Vegetation (SAV) Synthesis Project brought together experts from the Chesapeake Bay Program (CBP) partnership specializing in SAV, water quality, and land-use research and management. The goal of the project was to conduct a synthesis of multiple long-term datasets to determine what role the growing human population in the Chesapeake Bay watershed has played in influencing SAV distribution and abundance and if the sustained efforts and management actions implemented by the CBP partnership have benefited SAV habitat.

In response to interest from resource managers, local planners, and watershed organizations, the SAV Synthesis Project team conducted segment-specific reviews of SAV trends and progress towards restoration targets and created SAV fact-sheets for each segment. This local-scale segment review aims to provide a summary of information that may guide local planning and implementation of best management practices (BMPs) to encourage SAV recovery throughout the Bay.

The information provided in these fact sheets, along with accompanying data and information linked or referenced, should serve as references and guidance for resource managers and local planners in the identification and implementation of BMPs that benefit SAV recovery in their creeks, tributaries, or jurisdictional areas.

SAV Regulatory Review

The below resources, developed by the Chesapeake Legal Alliance in partnership with the SAV Workgroup, include a comprehensive regulatory review for Chesapeake Bay SAV and an accompanying searchable database for CB SAV statutes, regulations, and relevant policies. This work was funded through the Chesapeake Bay Program Goal Implementation Team (GIT) Funding Program.

Social Marketing Campaign to Promote SAV Stewardship

The below resources, developed by Action Research, Inc. in partnership with the SAV and Communications Workgroups, include social marketing materials to promote SAV stewardship. This work was funded through the Chesapeake Bay Program Goal Implementation Team (GIT) Funding Program.
