[email protected] Oregon White Oak (Quercus garryana) habitats are well documented in the Willamette Valley/Puget Trough ecoregion, however they are generally associated with upland sites. Less attention has been given to culturally important oak savanna and associated wet prairie habitats found in the tidally influenced floodplain of the Lower Columbia River (LCR). Remnants of low elevation Oregon white oak habitat are scattered across the floodplain from Vancouver, WA to the Cowlitz River. Disturbance regimes driven by flood, fire, and Native American land use no longer shape the landscape. Oak savanna habitats in the floodplain that have not been converted to agriculture are shifting to woodland, and are only identifiable by savanna form oaks surrounded by forest species. Wapato Valley Mitigation and Conservation Bank (Wapato Valley) is being developed as a mechanism to protect the legacy of environmental stewardship for future family generations. The objective of this research was to understand ecological drivers of oak distribution across tidally influenced floodplains to increase the success of oak savanna restoration at Wapato Valley. Biologists collected data on the elevation, location, hydrologic regime, stand structure and plant community, and conducted a thorough literature review.
