Summary:
Purpose: This project will assess the consequences of expansion of coastal willow Salix caroliniana in sawgrass Cladium jamaicense-dominated wetlands on plant community composition and ecosystem water and carbon exchange. Methods: Research will be conducted at Blue Cypress Conservation Area, an impounded sawgrass peatland within the St. John’s Water Management District SJWMD located in Vero Beach, FL. It is part of the River Basin Project controlled by SJWMD and the US Army Corps of Engineers, which moderates flooding, protects water quality, and reduces the amount of freshwater diverted to the Indian River Lagoon. Plant transpiration and CO2 exchange will be measured on fully expanded, non-damaged leaves of sawgrass and willow using a portable infrared gas analyzer LI-6400, LI-COR, Lincoln, NE, U.S.A.. Plant community composition in both habitats will be surveyed along with measurements of microhabitat conditions and water quality. Results: The results obtained from this study will provide a better understanding of physiological responses and community changes that may occur in sawgrass habitats as a result of willow encroachment. It is anticipated that there will be differences in transpiration rates between the two species as well as changes to community structure and water quality. Measuring plant level physiological responses will help improve landscape level models of water exchange as well as inform water management decisions.
