Wildflowers of the National Forests in Alaska highlights 50 of
the most common wildflowers found in Alaska's two National
Forests, the Tongass National Forest and the Chugach National Forest.
The Tongass covers most of southeastern Alaska, and the
Chugach surrounds Prince William Sound. Unless otherwise
noted, plants discussed here occur throughout our area of
interest (Kenai Peninsula through the southern Panhandle).
This brochure was prepared by the Forest Service Alaska
Region Botany Program. The program's mission is to foster
conservation of native plants and plant communities on Alaska's National Forests.
