||An Alternative Futures Analysis (AFA) was conducted to demonstrate how models can be used to evaluate landscape design scenarios developed for the Farmington Bay area of the Great Salt Lake. Scenarios were developed which featured the design of a conservation 'future' focused on a set of wetland protection, restoration, and conservation practices. The conservation design was contrasted with scenarios that reflect current day wetland management practices and an extrapolation of those practices into the future. Each of the future scenarios was described in context with the average water level elevation of the Great Salt Lake and a high water level elevation (4,200 feet and 4,212 feet, respectively). In addition, a set of wetland 'templates' was developed and embedded into each scenario to aid scenario design and evaluation. Each template represents a typical cluster or complex of wetlands with a dominate wetland class: impoundment wetlands, playa wetlands and fringe/emergent wetlands. Evaluation of the scenarios was based on risks to avian habitat support caused by degradation in wetland abundance, distribution, and condition. The evaluation entailed the use of four ecological modeling approaches. A wetland landscape profile was developed to track change in wetland abundance, by class, across the scenarios. A Geographic Information System (GIS) based avian wetland habitat assessment (AWHA) was developed to predict the availability of suitable avian habitat. The ArcView Generalized Watershed Loading Function (AVGWLF) model was calibrated to predict nutrient loads to the wetlands. A wetland cellular water quality model was developed to evaluate nutrient retention in impoundment class wetlands. No specific analysis was conducted to determine the effects of nutrient loads on the ecological condition of receiving wetlands.

||"This research project was conducted to develop a way of forecasting and quantifying the cumulative effect of management practices on the future management of wetland ecosystem services. The study is focused on wetland support for biodiversity, and specifically examined management risks to the avian habitat. Retention, recovery, and removal of excess nutrients by the wetland resource were also analyzed. No specific analysis was conducted to determine the effects of nutrient loads on the ecological condition of receiving wetlands. It was beyond the scope of the project. Future efforts to determine the effects of nutrient loads on the ecological condition of receiving wetlands will likely involve the systematic monitoring and assessment of wetlands in the project area over time. Information about the development and deployment of a wetland-monitoring program for the Great Salt Lake can be found on the Utah Department of Environmental Quality website."
