Ecoclass codes constrain allowable values for potential vegetation, plant association, plant association group (subseries), and series codes used in the Pacific Northwest Region. This standardization provides for a common language on these plant communities, thus avoiding duplication and confusion. See metadata document for specific details.

• Ecoclass Code Set (HTML)
• Ecoclass Codes Crosswalked to IMAP PVTs and VDDT Models
• Ecoclass codes Crosswalked to ILAP Potential Vegetation Type
• Current Master Crosswalk of Potential Vegetation Zones and Subzones to Other Entities
  • This spreadsheet provides a crosswalk of Potential Natural Vegetation (PNV) ecological zone and subzones to Omernik Level III Ecoregions, Northwest Forest Plan Physiological Regions. ILAP PVTs, LANDFIRE Biophysical Settings, and Fire Regime Groups.  At landscape scale, it is intended to apply to a wide variety of uses, such as for framing landscapes in the Northwest Plan.

The ILAP team used several tools, all of which are available to the general public and some of which is free. Generally, the team used maps in a geographical information system (GIS) software to summarize initial conditions for broad ecological regions in Oregon and Washington.

The maps used to get a snapshot of current conditions were:

• Forest composition and structure developed from gradient nearest neighbor (GNN) imputation (available on the Lemma website) and
• Potential Vegetation Types (PVT) developed by the US Forest Service

The GNN vegetation data was summarized by PVT and then entered into the Vegetation Dynamics Development Tool (VDDT) software, which models how vegetation might change over time given certain assumptions about the typical natural disturbances and growth rates for an ecological region. State and transition models were initially developed in VDDT; the software was updated and renamed SynchroSim (or STSim).

The goal here is to provide a way for the general public to analyze their own part of the world. The first step would be to get an idea of initial conditions, either by using the GNN and PVT data to summarize overstory and understory vegetation, or by using personal expertise and local data. The next step would be to enter the initial conditions into the STSim model for your region, and then run the models for the desired number of years to get a sense of what your part of the world may look like in 10 or 100 or 150 years.

Experienced GIS users may want to download GNN and PVT layers to summarize data. Experienced STSim users may want to run the models and tweak them based on their own expertise or out of sheer curiosity. People interested in the model results, but who do not feel comfortable with the technology, can go to the Model Products and Publications section of this site. Users of the modeling software STSim can download the models developed by the ILAP team. Getting the software is easy and free, although you will need a password to extract the installation program. Register with the STSim Software Coordinator, who will email the password to you.

An explanation of how to download STSim models from this website and pull them into the STSim software is provided further down this page. The Access databases that can be brought into a STSim session are provided below, organized by region. Please keep in mind that while the ILAP team coordinated the regional boundaries with the Lemma team, the GNN Modeling Regions are numbered differently.

All STSim Access database files are zipped to reduce download times. Regions are for the purpose of State and Transition Models; they are not the same as the ecology program areas.

• Region 1 – Blue Mountains
• Region 2 – Southern Central Oregon (called “East Cascades – Oregon, South” on Lemma site)
• Region 3 – Northern Central Oregon (called “East Cascades – Oregon, North” on Lemma site)
• Region 4 – Southwest Oregon (called “Klamath Mountains – Oregon” on Lemma site)
• Region 5 – Northwest Oregon (called “Coast Range – Oregon” on Lemma site)
• Region 6 – Southeast Oregon (called “Northern Basin and Range – Oregon” on Lemma site)
• Region 7 – Columbia Basin (called “Columbia Plateau” on Lemma site)
• Central Washington
• Eastern Washington
