Primary Productivity of Minor Marsh Plants in Delaware, Georgia and Maine

Description: Abstract: "This report summarizes the importance of common species of salt marsh plants inhabiting wetlands of the eastern U.S. coast. An evaluation of the ecological significance of the plants is based on their rates of primary production, morality, and contribution of detritus to the estuarine dependent systems. The data are important in reaching decisions relative to the deposition of dredged material in these coastal wetland systems."
