Cascadian Bioregion Map

The Cascadian Bioregion Map outlines a natural geographic area encompassing parts of the Pacific Northwest, including regions of British Columbia, Washington, Oregon, and northern California. It highlights ecological and environmental boundaries based on shared ecosystems, river systems, and landscape features, rather than political borders. This map is used to understand regional ecological health, manage natural resources sustainably, and support conservation efforts by recognizing the interconnectedness of forests, watersheds, and wildlife within this bioregion.
