Wallula Gap Biological Station at Whitman’s Braden Farm
The Wallula Gap Biological Station (WGBS) is an arid grassland and shrubland that serves as a resource for teaching and research. The station encompasses approximately 1800 acres (~730 hectares) in Western Walla Walla County, Washington and is managed by the Whitman College Biology Department with the consent of the Whitman College Farm Committee. Contact the WGBS director to obtain written permission for site use.
Topography and vegetation at WGBS vary and include miles of canyon slopes of deep loess soils, ‘scabland' sites of shallow soils and exposed bedrock scoured by the Missoula floods, extensive native bunchgrass stands, remnant sagebrush, as well as areas heavily invaded by annual weeds such as cheatgrass and yellow star-thistle.
