The focus of my research involves relationships between vegetative communities, hydrologic drivers, and soil properties of wetland forests and marshes. My study sites include oligohaline to freshwater tidal marshes, freshwater tidal forests, and non-tidal coastal wetland forests. These areas have vegetative communities that act as a good response variable for investigating the combined effects of long-term global climate change forces, episodic human-induced impacts, and regional weather patterns - especially drought. The most common methods I use to collect data include a variety of destructive and non-destructive vegetation surveys, autonomous water quality and quantity loggers, and measurements of tree sap flow (a proxy for transpiration). I analyze these data to discern relationships between vegetation communities and the environmental drivers of interest, determine the effects of management on carbon sequestration and functioning of wetland trees, and model stand water use of forested areas under differing community compositions and/or environmental stressors.
