About Us ...

The Columbia Basin Chapter includes member groups from two locales: the Tri-Cities, Washington at the confluence of the Columbia, Yakima, and Snake Rivers; and Walla Walla, Washington located at the base of the Blue Mountains. A wide variety of habitats and great diversity in native flora exist in the surrounding region. Centered in the dry shrub-steppe region (annual average of 7 in. precipitation) of the lower Columbia Basin, landscapes surrounding the Tri-Cities are dominated by bunchgrasses and sagebrush (Artemisia species). To the east, Walla Walla lies within the rolling hills of the Palouse Prairie or steppe region of Washington where deep loess soils support bunchgrass prairies that grade into shrubs and Ponderosa pine in the foothills leading to the forests and flowers of the Blue Mountains.

Since 1997, our chapter has been working to preserve our native flora and provide information to the public. Recent conservation/restoration efforts in the Tri-Cities include planting and seeding at Badger Mountain Preserve (Friends of Badger Mountain), planting and signage at the natural area in Leslie Groves North, and restoration at Horn Rapids County Park near Richland. In Walla Walla, efforts are focused on native plant containers in the downtown gardens, a native plant demonstration garden at the Humane Society, and developing and publishing a wildflower and trailside native plant guide.
