The <br /> r ar s ec existing ditched segment of Willow Creek would be abandoned and possibly <br /> restored to prairie. Impacts to rare plant populations will be avoided. <br /> ___________ T <br /> lb • Enhance adjacent wetland and upland prairie communities on BLM and TNC <br /> 11th Avenue lands (approximately 90 acres of wet prairie and 20 acres of upland prairie). <br /> – • Create habitat for the state and federally listed species including Fenders blue <br /> ° butterfly, Kincaid's lupine, Bradshaws lomatium, Willamette Palsy, Western <br /> pond turtle, and Western meadowlark. <br /> • Create trail connection between the rldgeline trail corridor to the south and the <br /> Fern Ridge path to the north.
