 Knez Preserve
Total acreage: 1.87 acres
Date acquired by TWC:
Location: Tigard, Oregon
Key TWC staff or board member: Jennifer Wilson
Site Description:
The Knez Preserve is one of the few known tufted hairgrass prairies in the Portland Metro area, a plant community in great decline in the Willamette Valley. It is estimated that less than 1% of the wetland prairie present at the time of Euro-American settlement remains. Nestled between Red Rock Creek, Highway 217 and industrial development, the preserve provides safe haven for this small remnant population of tufted hairgrass.
Historically, the area was part of a larger wetland that extended upstream along Red Rock Creek. This “Red Rock Creek Wetland” was probably more than 25 acres in size and contained a mix of forested, shrub, emergent and open water wetland types.
Access
Site access is limited.
Site Management: Conducted by TWC and volunteers.
