Abstract The distribution and abundance of Submerged Aquatic Vegetation (SAV) in the lower Chesapeake Bay is given in the report. All SAV were mapped from aerial imagery onto topographic quads (1:24000) with a zoom transfer scope. The SAV beds were classified into 4 density categories based on comparison with a crown density scale. A comparison with earlier surveys indicates that the distribution of the SAV species found in the saline portions of the Bay have shifted. SAV beds in six selected areas of the lower Bay were examined for historical changes in the distribution and abundance of SAV. Significant declines were noted in the period of 1971 through 1978. The distribution of SAV species in Virginia's tidal waters was classified into three groupings: (1) (Zostera and Ruppia) dominates the saline portions (2) (Potamogeton, Zannichelia) Ologohaline regions (3) (Ceratophylum, Majas) fresh water.
