Natural resources presented in this Natural Resource Condition Assessment (NRCA) were divided into four general areas: physical resources, water-related resources, ecosystem integrity, and focal animal communities. The approach of this NRCA was to use existing data to evaluate the condition of natural resources at GETT and EISE. Thresholds for condition (good, moderate concern, and significant concern) were obtained from a variety of resources such as federal and state regulations (e.g., water quality criteria), peer-reviewed literature, study reports, and in some cases when threshold values were not available, best professional judgment. If possible, trends in the condition (improving, deteriorating, or unchanging) were also evaluated. And finally, an estimate of the confidence in the assessment was provided based on the quality and quantity of available information (high, medium, low confidence). The assessment of condition used standardized symbology provided by NRCA guidelines are presented.
