The boundary for the SIR was extended into Washington State as part of the Shining Mountains Project, which was developed by the provincial government with numerous federal, provincial and state government, academic, and First Nations/tribal partners in British Columbia, Alberta, Yukon, Alaska, Washington, Idaho, and Montana in the 1990s. The purpose of the Shining Mountains Project was to determine the extent and distribution of regional and zonal ecosystems which British Columbia shared with its neighboring jurisdictions (MSRM, 2005). In Washington, the boundary also corresponds with The Nature Conservancy’s (TNC) ecoregion framework based on Bailey’s (1994) ecoregion map for the United States. Ecoregions are large areas of land or water defined by their distinct climate, geology, and native species.

The boundary utilized for the OkanaganEcoregional Assessment corresponds veryclosely with the British Columbia EcoregionClassification system’s delineation of theSouthern Interior Ecoprovince (SIR) (Demarchi,1996). The boundary for the SIR was extendedinto Washington State as part of the ShiningMountains Project, which was developed by theprovincial government with numerous federal,provincial and state government, academic, andFirst Nations/tribal partners in British Columbia,Alberta, Yukon, Alaska, Washington, Idaho, andMontana in the 1990s.
