Abstract
Long-term studies by the U.S. Geological Survey (USGS) at the Cottonwood Lake Study Area in North Dakota have related seasonal and inter-annual climatic fluctuations to temporal changes in water levels, flooding regime (e.g., ephemeral, seasonal), water chemistry (e.g., salinity), hydrologic function (e.g., recharge, discharge), and biological communities (e.g., plants, invertebrates, amphibians and birds) in a diversity of prairie wetland types. These data provide an opportunity to develop habitat models to predict and relate changes of wetland biological communities to hydrogeochemical changes attributable to climatic variation. However, models also could be calibrated for monitoring and evaluating the influence of land-use change on the health and sustainability of both uplands and wetlands composing the prairie ecosystem. Such models would provide land management agencies with a method to separate temporal and spatial changes in ecosystem benefits (e.g., erosion, carbon sequestration, and wildlife) due to natural variation from those related to upland and wetland conservation programs. The applied value of developing the capability to conduct evaluations that encompass both the aquatic and terrestrial ecosystems is reflected in current activities being pursued by land management agencies and is a necessity for maintaining wetland processes.
