The H. J. Andrews Experimental Forest occupies the 6,000-hectaredrainage of Lookout Creek, a tributary of the McKenzie River, on thewestern slopes of the Oregon Cascade Range in west-central Oregon(fig. 1). This experimental forest has been administered by the U.S.Forest Service for scientific and educational purposes since its estab-lishment in 1948. It is an active center for watershed, timber manage-ment, and ecological research programs of the Pacific Northwest Forestand Range Experiment Station and the Coniferous Forest Biome's Analysisof Ecosystems Project in the International Biological Program. Thischecklist of vascular plants encountered on the forest during the first20 years of its existence will assist scientists working on the forest,and other interested visitors, in plant identification.
