A bioregion is defined in terms of the unique overall pattern of natural characteristics that are found in a specific place. The main features are generally obvious throughout a continuous geographic terrain and include a particular climate, local aspects of seasons, landforms, watersheds, soils, and native plants and animals. People are also counted as an integral aspect of a place's life.
The term bioregion is simply short for 'bio-cultural region'. For the Cascadia bioregion, it means the Pacific Northwest as defined through the watersheds of the Fraser, Columbia and Snake rivers - boundaries and borders which better accurately reflect the geographic, economic and cultural realities of the land and people living there. This idea of a bioregion is part of a ethics and philosophy called "Bioregionalism", which means that by sharing the same area and watersheds, we will have shared values, and common concerns, and those who live there will be the best able to know what they need, and how to handle the issues unique to their watershed.
The main features are generally obvious throughout a continuous geographic terrain and include a particular climate, local aspects of seasons, landforms, watersheds, soils, and native plants and animals. People are also counted as an integral aspect of a place’s life, as can be seen in the ecologically adaptive cultures of early inhabitants, and in the activities of present day reinhabitants who attempt to harmonize in a sustainable way with the place where they live. Cascadian bioregionalism deals with the connected ecological, environmental, economic and cultural ties that are prevelent throughout the Pacific Northwest and distance the area from their eastern counterparts. The argument is that those in Washington and Oregon have much more in common with those in British Columbia than those in Washington D.C. An argument which continues to gain ground as we enter a more global age, and as efforts to create integrated transportation and economic systems, stem pollution and global warming, and support sustainable alternatives increasingly requires the commitment of larger regional players.
The Cascadia Bioregion also referred to as the Pacific Northwest Bioregion) encompasses all or portions of Washington, Oregon, Idaho, California, Nevada, Wyoming, Montana, Alaska, British Columbia, and Alberta. Bioregions are geographically based areas defined by land or soil composition, watershed, climate, flora, and fauna. The Cascadia Bioregion claims the entire watershed of the Columbia River (as far as the Continental Divide), as well as the Cascade Range from Northern California well into Canada. The delineation of a bioregion has environmental stewardship as its primary goal, with the belief that political boundaries should match ecological and cultural boundaries.
