Waterfowl species populations in Maryland and Virginia portions of Chesapeake Bay were examined during long-term and current (1972-1980) periods to identify trends in distribution and abundance. Comparisons were also made between State and Atlantic Flyway populations and waterfowl species distributions among survey areas. Distribution and abundance of submerged aquatic vegetation among waterfowl survey areas in Md. were summarized for 7 plant species during 9 years (1971-1979). These data (SAV species combined) were used to test the hypothesis that annual variation in area populations of waterfowl was related to variation in the abundance of SAV, following an adjustment for annual variation in the general abundance of waterfowl. There were few statistically significant relationships between distribution and abundance of waterfowl and SAV.
