Our research synthesis was based on the following publications. Since our focus was on wildlife ecology and conservation, our citations are most comprehensive in those areas. Also included are a number of other sources for background information on the natural and human history of the Willamette Valley. An excellent online resource for information about Willamette Valley prairie and savanna plant communities is Mark Wilson's Willamette Prairies website.
