Utah and Colorado Plateau: Terrestrial and Aquatic Intactness

About
This gallery displays estimates of terrestrial and aquatic intactness (i.e. current condition) based on the extent to which human impacts have disrupted the landscape of Utah and the Colorado Plateau Ecoregion. Intactness values are high in areas where anthropogenic impacts are low.
The Utah-Colorado Plateau REA stepdown analysis was conducted for UT DNR and BLM. It was performed using EEMS (Environmental Evaluation Modeling System), an open-source, geospatial logic modeling system developed by the Conservation Biology Institute. Logic modeling creates a flexible framework that hierarchically integrates numerous and diverse datasets into composite layers, quantifying information in a continuous rather than binary fashion. This technique yields accessible decision-support products that help drive scientifically-rigorous management strategies.
The input data, intermediate layers, and final results of this analysis can be explored via the EEMS Explorer of Data Basin (http://databasin.org/), where they are accessible as online interactive maps.
Aquatic Intactness, HUC6 (12-Digit NHD Hydrologic Unit Code) resolution:
These datasets estimate the extent to which human impacts have disrupted the hydrology, water quality, and habitat quality of aquatic systems.
Terrestrial Intactness, 1 km2 resolution:
These datasets estimate the extent to which human impacts such as agriculture, urban development, natural resource extraction, and invasive species have disrupted the landscape.
Aquatic Species Habitat Intactness Overlays:
Habitat condition within a species' estimated distribution, modeled at the sub-watershed (HUC6) scale.
Species distributions were estimated based on observation points and rivers and streams extracted from the National Hydrography Dataset (NHD). Condition estimates are not species-specific, and local data on species' distributions and habitat requirements (beyond those captured in this model) should be considered before making management decisions.
These datasets estimate the extent to which human impacts have disrupted the hydrology, water quality, and habitat quality of aquatic systems.

The webinar presented on December 17th, 2015, "Mapping aquatic condition to facilitate informed management decisions", gives a high-level overview of the process used to create these data.
