<p>This Chesapeake Bay Program indicator of progress toward the <a href='https://www.chesapeakeprogress.com/abundant-life/sav' rel='nofollow ugc'>Submerged Aquatic Vegetation Outcome</a> shows beds of underwater grasses across the four salinity zones of the Chesapeake Bay. The GIS layers were mapped from 1:24,000 black and white aerial photography. Each area of SAV was interpreted from the photography and placed into one of four density classes based on the percentage of cover. The dataset contains all SAV areas that were identified from the areas flown. Some areas that are presumed to contain no SAV were not flown. Some small beds, particularly along narrow tributaries, may not have been distinguishable.</p>
