What Makes Tom McCall Preserve Special
The Tom McCall Preserve is open from March 1 to October 31 due to the high risk of erosion and ground disturbance in the wetter months.
Located in the transition zone between the moist, heavily-forested west side of the Cascades and the drier bunch grass prairies of the east, Tom McCall Preserve comes into spectacular bloom every spring.
Lava flows, catastrophic floods and volcanic ash deposits shaped a mound-and-swale topography that perplexes the experts. Earthquake sorting, freezing and thawing, erosion, soil accumulations by plants and wildlife burrowing activities have all been suggested as having caused the mounds.
What TNC Has Done/Is Doing
The preserve is named for Oregon's late governor, Thomas Lawson McCall, whose commitment to conservation in Oregon remains an inspiration. A patchwork of ownership includes the Conservancy, Mayer State Park and national forest lands. The preserve is managed in cooperation with these agencies.
The rare plant populations are monitored by ecologists, and in spring and summer, volunteer docents lead interpretive hikes. Stewards and volunteers manage the weeds and maintain the trails throughout the year.
With assistance from the Portland Garden Club, Berry Botanic Garden, Native Plant Society of Oregon and others, the Conservancy also created a native plant garden in the turnaround at the viewpoint.
