Willamette Valley wetland prairies developed on soils with clay layers that prevent the drainage of winter rains, causing flooding between fall and spring. In contrast, upland prairies are found on sites with well-drained soils and no prolonged standing water. The two types of prairies support different plants and animals, differ in their structure and productivity, and need different types of management.

The papers and reports listed in this section discuss the vegetation and management of wetland prairies of the Willamette Valley.
