The Okanagan Ecoregion is divided into 5sections that roughly match the British ColumbiaEcoregion Classification’s ecoregion-leveldelineation in the Shining Mountains Project,with the exception of the Thompson OkanaganPlateau which was split into two sections. In thecontext of the British Columbia classificationsystem, the term “ecoregion” applies to a lowerlevel of ecological system classification thanhow it is being applied in this ecoregionalassessment context. The term ecoregion isroughly equivalent to the BC classification’secoprovince level of classification. In the BCclassification, ecoprovinces are areas withconsistent climatic relief and regional landforms,and ecoregions are areas with majorphysiographic and minor macroclimaticvariation. The Okanagan Ecoregion falls withinthe Dry Ecodomain which is an extension of thedry climate regime which extends up from theinterior of northern Mexico and the northwesternUnited States. The two most commonlyrecognized climates are arid desert and semiaridsteppe.
