Submerged Aquatic Vegetation in the Chesapeake Bay: A Barometer of Bay Health

In 1978, a program was initiated in the Chesapeake Bay region to investigate the decline of submerged aquatic vegetation (SA V), potential factors that may have led to its decline, its distribution and abundance, and its .role and value. The program began with little available background data, but some very basic questions about SAV in the Bay were answered in the approximately three years of research that were funded. For example, it was determined that the decline of SAV was Baywide. All SA V species were affected and the decline was unprecedented in the recent history of the Bay. A second important finding was that the decline of SA V was most probably not related to any specific contaminant per se (e.g., herbicide contamination) but appeared to be related to deteriorating water quality in the Bay.https://scholarworks.wm.edu/vimsbooks/1160/thumbnail.jp
