Balsamorhiza and CastellijaPerspectives: The ecology of Willamette Valley plants

Regeneration from seed is a crucial step for increasing the abundance of these species, but little is known about the conditions that promote seedling establishment.--Clark, Wilson, and Goodridge (2001)

Willamette Valley prairies support a wide range of interesting plants. Because plants are the core of the prairie, prairie preservation and management should start with a fundamental understanding of plants.

The papers and reports listed in this section discuss ecological aspects of the plants of Willamette Valley prairies.
