The Washington State Department of Ecology is the state of Washington's environmental regulatory agency. Created in February 1970, it was the first environmental regulation agency in the U.S. predating the creation of the Environmental Protection Agency by several months.

This is the corollary data set to Combined Origin Year Raster, and is calculated as CURRENT YEAR - COMBINED ORIGIN YEAR.  Origin year is calculated from multiple data sources using the following logic: Origin year is reported at the pixel-level (1/10th ac scale). The default value is the predicted origin year, based on RS-FRIS models. These models rely on remotely sensed data (LiDAR and PHODAR) and are constructed primarily from height-to-age relationships. The default RS-FRIS predicted ages are overwritten using the following data, if available: Tree core data from DNR's historic inventory (FRIS) is used for stands whose origin year is 1900 or earlier. FRIS tree core data from younger stands (post-1900) or FRIS data based on stratified samples is used only if RS-FRIS data is not available.  Information from LRM for sold or completed final harvest (VRH, CLEAR_CUT, SEEDTREE_REM, SHELTER_REM) and completed planting (REGEN) activities was used if available. For variable retention harvests, clear cuts, and regen plantings, STAND_ORIGIN_DT was used if populated, otherwise FMA_DT. For seed tree removals and shelter wood removals, STAND_ORIGIN_DT was used if populated. Activities completed prior to the acquisition of the remotely sensed data (i.e., if the activity is visible in the imagery) used RS-FRIS predicted ages for leave tree clumps and LRM data the regeneration cohort. Activities completed after acquisition of the remotely sensed data (i.e., activity not visible in the imagery) used LRM data for the entire stand. Data sources are mapped in the "Combined Origin Year Data Source" raster.
