COLUMBIA HIlls Nap
Ecoregion: Columbia Plateau (Klickitat County)
Columbia Hills Natural Area Preserve (NAP) is located on the crest of the Columbia Hills at the east end of the Columbia River Gorge National Scenic Area, 17 miles southwest of Goldendale, adjacent to Columbia Hills State Park. At 3,600 acres, it is the state’s largest natural area preserve. Columbia Hills NAP was established in 1993 after being identified by the Washington State Natural Heritage Program as a priority for protecting Washington’s largest populations of three rare plants: obscure buttercup (Ranunculus reconditus) — state endangered, Douglas’ draba (Cusickiella douglasii) and hot-rock penstemon (Penstemon deustus var.variabilis), both state threatened.
The NAP also supports the largest known high-quality examples of two plant communities: Idaho fescue-houndstongue hawkweed grassland (Festuca idahoensis-Hiercacium cynoglossoides), Douglas’ buckwheat / Sandberg’s bluegrass scabland (Eriogonum douglasii / Poa secunda), and thyme buckwheat / Sandberg’s bluegrass scabland (Eriogonum thymoides / Poa secunda). Oak-pine woodlands, basalt cliffs, and a number of natural springs add to the diversity of habitats found on this large site.
Columbia Hills NAP is home to a variety of wildlife species including mountain lion, black bear, mule deer, porcupines, Douglas tree squirrels, coyotes, and several snake and lizard species. Large numbers of birds, including neotropical migrants and raptors, nest and feed in the various habitats within the NAP. A rich and well-documented cultural history and exquisite panoramic views contribute to this site's significance.
Science, Research and Monitoring
Public and private universities, other research institutions and individual researchers may contact DNR to propose a research project at the site. If you are interested in pursuing research at Columbia Hills NAP, please contact David Wilderman, Natural Areas Ecologist, at email@example.com
Examples of research and monitoring projects that have been carried out at Columbia Hills include:
- Rare plant population monitoring, including an annual volunteer effort tracking the obscure buttercup.
- Comparison of genetic diversity of the rare obscure buttercup and the common sagebrush buttercup.

Environmental Education and Public Access
A primitive road that climbs 2 1/2 miles through the NAP to the ridge-crest is open for pedestrian access, with a small parking area and information kiosk located at the entrance. Walking this road provides visitors with close-up views of many of the wildflowers that grow along the 1,200-foot elevation gradient that the road traverses, as well as stunning views from the ridge-crest.
The site is frequently used for organized field trips by native plant groups, geologists, archaeologists, and birding groups. The adjacent Columbia Hills State Park offers additional opportunities including hiking, camping, and interpretive tours. The annual “Wagons and Wildflowers” event, held on the first Saturday in May, showcases the natural and historical resources of both the NAP and State Park.
For information on educational opportunities, please contact the DNR Southeast Region Natural Areas Manager.
Volunteer and Stewardship Opportunities
Volunteers help with a variety of activities on Natural Areas, including invasive species control, restoration, and monitoring. If you are interested in volunteer and stewardship opportunities at Columbia Hills NAP, please contact the Southeast Region Natural Areas Manager.
