Lost Prairie was designated as an Area of Critical Environmental Concern to protect 60 acres of mid- to high-elevation sedge fen, Sphagnum bog, and beaver marshes in the Oregon Coast Range. The fen supports a diverse array of vascular plants and bryophytes that are uncommon in coastal coniferous forests of northwestern Oregon. Saddle Bag Mountain Research Natural Area occupies 300 acres on the 3,290-foot summit and western slopes of the mountain and was established to protect one of the last remaining stands of Pacific silver fir in the Oregon Coast Range.
