ICF's Ecosystem Diagnosis and Treatment system (EDT) was developed more than 15 years ago as an application of the medical model of diagnosis and treatment to watershed management issues.

The first EDT tool was developed in an offline database environment and focused almost exclusively on Chinook, coho, and steelhead in their freshwater life stages.

The second version of EDT included its evolution to a web-based environment, and provided a shared system for cooperative basin planning. EDT has been used throughout much of the Columbia Basin and Puget Sound in the Pacific Northwest of the United States. While there was much strength in these systems, modern ecosystem management problems present ever increasing challenges for flexibility, integration, and transparency.

Ecosystem Diagnosis and Treatment 3.0 (EDT3) is a modernized toolset based on public-facing web services and the Windows™ Presentation Foundation™ environment. It leverages the power of desktop computers while providing opportunities for integration with outside web services.

EDT3 is designed to offer integration with U.S. Army Corps of Engineers (ACOE) Hydrologic Engineering Center (HEC) data, U.S. Environmental Protection Agency (EPA) hydrological unit data, and a variety of geographic information system (GIS) data sources. The system includes a more flexible data management and reporting structure that allows for evolutionary significant unit (ESU)-specific species habitat-relationship rules, habitat status and trends reports, and variable out-of-basin conditions. The model provides a more comprehensive user interface for designing, testing, implementing, and publishing EDT models. Importantly, EDT3 can utilize data created in EDT2, allowing users to build on past investments.

Why is EDT3 Important?

  • Habitat status and trends—evaluate changes in ecosystem conditions through time and determine revised management priorities
  • Complex networks—evaluate bypass systems, split channels, multiple fish ladders, dendritic estuaries, and branched networks
  • Expanded applications—modernized information structure allows for ready adaptation to new watersheds, species, and ESUs using new life history information, species-habitat rules, and environmental attributes

Key Features of EDT3

  • Enterprise class menu-driven user interface allows for intuitive navigation and web service enabled .net code library allows for integration with public data sources and automatic online updates
  • Online storage and data management offers improved organization and efficiency using the EDT3 file explorer
  • Improved workflow provides a more efficient application of biological information such as spawning reaches, life history data, and trajectories
  • Publication system provides public access to online and downloadable performance, diagnostic, and prioritization reports

ICF provides clients with quantitative tools, analyses and applications to meet the complex and sometimes stringent legal and scientific needs of 21st-century natural resource management. We combine in-depth biological and ecological knowledge with mathematics, computer modeling, software development and data management to create quantitative tools that facilitate a collaborative, scientific approach that works and will withstand legal and scientific scrutiny.

Our team of scientists, mathematicians, and software developers has experience worldwide in virtually every biome bringing creative and efficient solutions to today’s freshwater, marine, and terrestrial natural resource projects.
