Butterfly Meadows Perspectives: Upland prairies

Willamette Valley native upland prairies, along with wetland prairies, now cover much less than 1% of their former area making them among the rarest of North American ecosystems--Wilson (1998)

Willamette Valley upland prairies developed on sites with well-drained soils and no prolonged standing water. In contrast, wetland prairies are found on soils with clay layers that prevent the drainage of winter rains, causing flooding between fall and spring. 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 aspects of upland prairies of the Willamette Valley.
