Willow Creek Work Party


Register for the Willow Creek Work Party

Willow Creek's native grasslands, ash woodlands and perennial streams provide the best remaining example of native wet prairie habitats in the southern Willamette Valley.

During this work party, volunteers will sow the seeds of native grass and wildflowers in a Fender’s blue butterfly restoration area and learn about TNC's local conservation efforts.
