1) Increased rainfall during the dry season will keep water tables high, reducing the flux of brackish groundwater discharged into tan he mangrove ecotone. This decrease in coastal groundwater discharge will reduce the amount of phosphorus discharged into the mangrove ecotone, minimizing their productivity (e.g., decrease in biomass, less elevated canopy). 2) During typical dry seasons, seawater from the Gulf of Mexico intrudes along the southwestern Florida coast, which will increase brackish groundwater discharge into the mangrove ecotone and supply it with phosphorus, increasing biomass production and canopy height. In addition, sediment deposited during storms will also be a source of phosphorus to the mangroves. 3) Extreme flooding during storms will decrease the density of salt-intolerant vegetation promoting the landward expansion of the mangrove ecotone, which can be detected using remote sensing. This increased mangrove landcover will be a result of elevated water levels (e.g., storm surge) and the ensuing higher salinities within the shallow aquifer zone. The combination of higher shallow groundwater salinity and increase in phosphorus inputs (i.e., coastal groundwater discharge, storm sediment deposition) will allow mangroves to effectively populate landward. This preliminary research and data analysis will be used
