EAGLES is a PC-based series of linked software applications (decision support tools or DSTs) in user-friendly ArcGIS and web-enabled environments. EAGLES allows biologists and managers direct control and access to powerful data processing and modeling capabilities for landscape planning and management of focal species and their habitats.


What does EAGLES provide across all LCC units?

  • Common Data

  • Standardized Data Protocols

  • Transparent Analysis Techniques


What do the tools within the EAGLES workflow allow practitioners?

  • Direct access to, and understanding of, climate and biophysical data products for ecosystem vulnerability assessments

  • Creation of conceptual, visual, and statistical models of species populations responding to environmental change

  • To explore What-if-Scenarios about how species and their habitats respond to habitat alterations and future climate conditions


What features of EAGLES allow practitioners to evaluate predictors of wildlife-habitat relationships and generate spatial models?

  • Access to free or low-cost remote sensing information products on vegetation, climate, habitat metrics, disturbance, etc. in a useable format, including datasets currently available or under development by the NASA Terrestrial Observation and Prediction System (TOPS) and other ecosystem assimilation models that produce geospatial data products like forage biomass.

  • Explanation of how this information is derived, created, integrated and validated and matched with species data sets prior to analysis.

  • Demonstration and guidance to user-friendly computer tools (ArcGIS and web-based) that access this information and provide automated summaries, trends, and visualizations for ecosystem vulnerability assessments. All tools are provide at no charge.

  • Access to simple-to-sophisticated statistical analysis, modeling, and prediction software tools that are user-friendly and take a ‘white-box’ (not black box) approach to species distribution and habitat modeling to identify critical habitats and corridors.

  • Access to “risk” models which integrate remote sensing data with species data, permitting assessment of environmental and cumulative impacts to species populations and their habitats under a variety of what-if-scenarios and future climate projections.


EAGLES was developed from a three-year NASA-funded grant focused on decision support for the US Fish and Wildlife Service’s Strategic Habitat Conservation (SHC) framework and Landscape Conservation Cooperatives (LCCs). State and federal agencies produce valuable species response datasets using techniques including telemetry, aerial surveys, and field plots. Meanwhile, new technologies like remote sensing satellites, airborne sensors, weather stations, distributed sensor networks, downscaled spatial data sets, and computer models are producing a ‘flood’ of information quantifying changing environmental/habitat conditions. Concurrent with the exponential growth of information is the parallel development of statistical techniques and increasing processing power (computer muscle) that, together, have the capacity to analyze datasets in powerful ways and turn the flood of data into a set of robust and actionable information for managers and decision makers.

Partner organizations involved in decision-making to manage fish, wildlife and plant resources need tools that give them practical access to this enormous amount of information and technology. The goal of YERC’s geospatial data products (climate, disturbance, vegetation, etc.) and their tools (EAGLES) is to efficiently make the most of long-term, legacy data sets, research projects, and ongoing monitoring and survey programs.
