The impact of deforestation on the exchange of water vapor and carbon dioxide between the atmosphere and the terrestrial land surface is the biggest concern with regard to the climate system, said Daley. Changes in their atmospheric concentration will have a direct effect on climate. Deforestation has decreased global vapor flows from land by 4 percent, according to a study published by the National Academy of Sciences.
Florida Wetlands are defined as: those areas that are inundated or saturated by surface water or ground water at a frequency and a duration sufficient to support, and under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soils.
In Florida, salt marshes are most abundant on coastlines above the winter freeze line (where they do not have to compete with mangrove wetlands), especially along the Big Bend area of the Gulf coast in low-energy shorelines, sands, lagoons and bays.wo grasslike species play unique dominating roles: 1  Smooth cordgrass (Spartina alterniflora) forms a border along open water in salt marshes. 2  Needlerush (Juncus roemerianus) comprises the largest vegetative zone and the bulk of the biomass in most salt marshes on the northeast Gulf Coast.
