SAV Home > 2012 SAV Report > Ground Surveys

Ground surveys were accomplished by cooperative efforts from a number of agencies and individuals. Although not all areas of Chesapeake Bay were ground surveyed, the data did provide valuable supplemental information. The ground surveys confirmed the existence of some SAV beds mapped from the 2012 1:24,000 scale aerial photography, as well as SAV beds that were too small to be visible on the 1:24,000 scale photography. The surveys also provided species data for many of the SAV beds. Ground survey information supplied to VIMS researchers is included on the SAV distribution and abundance digital maps and included in the VIMS SAV GIS Database. The group that performed each survey is designated by a unique symbol to identify the different methods of sampling. In many cases the symbols on the SAV maps have been offset from the actual sampling point to avoid confusion with the mapped SAV bed. Where species information was available, it is included on the map. Because of space limitations on the maps, occasionally one or more survey points are combined where the information was duplicated. All ground survey data supplied to VIMS are tabulated in the ground survey table.
