Such an assessment leads directly to some of the choices that lie before the public. To help frame some of these choices, the team chose a small sample of strategies to demonstrate broad choices and implications. The strategies should also educate us on the way parts of the system interact and should lead to a better understanding of unexpected ramifications brought about by human action. No single model of the Sierra that encompasses all interacting parts is possible. We have deliberately chosen several modelsmathematical and nonmathematical, quantitative and qualitativeto illustrate our strategies.
Models are only one way to organize and display a thought process.
Their use is to aid in understanding the implications of choices, in suggesting other choices, and in opening up the territory for informed decision making. This study has shown that options are available that could lead to better management. Contained in this summary is a list of condensed critical findings from the assessments, followed by an overview of the assessments and management strategies from the SNEP reports.
