The ability of wetland environments to support critical ecosystems services is diminishing due to declines in water availability. These changes are driven by climatic variability in weather patterns and by increasing demands for water from human populations. As a result, increasing pressures are being exerted throughout the hydrologic cycle. Declines in water availability via changes in rainfall patterns and extraction for human usage have resulted in detrimental changes to ecosystem services such as carbon sequestration in peatland soils and loss of soil formation capacities. Declines in surface water and surficial aquifer levels, have led to short and long-term changes in plant communities resulting in increases in evapotranspiration rates and decreases in soil infiltration capacities, further diminishing water supply for human use and baseflow that supports ecosystem function. In addition, changes in plant communities have led to increases in erosional processes, reduced rates of organic soil accretion and carbon loss from systems that experience organic soil subsidence. This session will focus on the ramifications of changes in hydropatterns on natural habitats throughout the United States and potential impacts from further climatic changes.
