GNN Modeling Regions and Schedule

GNN models and maps are being developed for modeling regions that approximate Level III ecoregions and that encompass areas needed by the Interagency Mapping and Assessment Project. The GNN modeling regions have been defined for Oregon and part of northern California, but are not yet developed for Washington.
