Description

Regional aquatic assessments are used to prioritize areas for conservation, restoration, or development. They are designed to summarize distributions of species and habitats and quantify stressors. Although these assessments have been used for decades, no standard approach has emerged. Two recent assessments spanned the Colorado Plateau ecoregion. Trout Unlimited (TU) used an indicator-scoring approach to assess the condition of wild trout habitat, and a BLM Rapid Ecoregional Assessment (REA) used “fuzzy logic” to quantify ‘aquatic intactness’. Both approaches produced HUC12 watershed scores, and we used a difference map to compare their outcomes. Scores were correlated (? = +0.57, p-value =
