A haven for rare plants, wildlife and grassland communities once abundant along the Oregon Coast, Cascade Head provides critical habitat for native prairie grasses, rare wildflowers and the Oregon silverspot butterfly.
North of Lincoln City, in Northwest Oregon
In the early 1960s, volunteers organized an effort to protect Cascade Head from development; by 1966 they had raised funds to purchase the property, after which they turned it over to The Nature Conservancy. Because of its ecological significance, Cascade Head Preserve and surrounding national forest and other lands have won recognition as a National Scenic Research Area and a United Nations Biosphere Reserve.
Thanks to your support, researchers are testing methods of maintaining and restoring grassland habitat for the Oregon silverspot butterfly, including prescribed fire. But it takes a few years for the early blue violet — the butterfly's host plant — to reach maturity. As a "stop-gap measure," the Conservancy teamed up with the U.S. Fish and Wildlife Service, Lewis and Clark College and the Oregon Zoo to gather female silverspots for captive rearing. After being hatched and raised at the college and zoo, their progeny are reintroduced as pupae to the preserve. See photos from a butterfly release.
Conservancy ecologists also monitor the populations of rare plants throughout the year. In spring and summer, teams of volunteers remove invasive species such as Himalayan blackberry, help maintain trails, assist with research projects and teach visitors about the preserve.

Additionally, our scientists are also helping evaluate sites off Oregon's coast to better protect natural resources, including
The Oregon silverspot butterfly, federally listed as a threatened species, is known to only five other locations in the world. The butterfly depends on a single plant species, the early blue violet (which grows coastal grassland openings), to serve as food for its larvae. Elk, deer, coyote, snowshoe hare and the Pacific giant salamander frequent the preserve, while bald eagle, great horned owl, northern harrier, red-tail hawk and the occasional peregrine falcon soar in hunting forays over the grassy slopes.
Formed by the uplift of underwater volcanic basalt flows, the headland is unusual for the extent of its prairies dominated by native species: red fescue, wild rye, Pacific reedgrass, coastal paintbrush, goldenrod, blue violet and streambank lupine. Rare wildflowers include hairy checkermallow and the Cascade Head catchfly, with 99% of the catchfly's world population found only here.
Each year an estimated 25,000 visitors hike Cascade Head Preserve to enjoy the views, wildflowers and wildlife.
Please observe the following guidelines while hiking:
There are two trails on Cascade Head. To reach the lower trail (a more vigorous hike to the top of the headland):
The upper trail (a more level 1-mile hike to the upper viewpoint) is closed by the U.S. Forest Service from January 1 to July 15. To reach it:
