In 2003, the CBP adopted the Strategy to Accelerate the Protection and Restoration of Submerged Aquatic Vegetation in the Chesapeake Bay including a commitment to plant 1,000 acres by 2008. The program partners have thus far planted 16% of their initial goal. In 2009, 9.6 acres were planted with funding from the National Oceanic and Atmospheric Administration and other sources. Both funding for SAV planting, and capacity for doing it, will need to be increased dramatically to meet the goal on time.

American shad were once the most abundant and economically important species in the Chesapeake Bay. Shad are anadromous fish and spend most of their lives in the ocean, returning to freshwater rivers to spawn after they reach maturity. Data for the York and Potomac Rivers were provided by the Virginia Institute of Marine Science via an ongoing Catch per Unit Effort (CPUE) study involving American Shad gill-netting. Data for the Susquehanna and James Rivers represent published fishway passage values for Conowingo and Boshers Dams, respectively.

This map shows progress toward achieving the Chesapeake Bay Program segment-specific underwater bay grass restoration goals. It is based on the single best year of acreage as observed through the most recent three years of data from the Chesapeake Bay underwater bay grasses aerial survey.
