Located on a rocky plateau above West Linn, Camassia Natural Area was The Nature Conservancy's first preserve in the state of Oregon. Sculpted by prehistoric floods, this nature preserve is home to over 300 plant species, including several rare Willamette Valley species particularly White Rock Larkspur (Delphinium leucophaeum). Its namesake wildflower -- Common Camas (Camassia quamash) -- blooms profusely in April and May. Other species include Rosy Plectritis (Plectritis congesta), Western Trillium (Trillium ovatum), Western Saxifrage (Saxifraga occidentalis), and Oregon fawn lilies (Erythronium oregonum). The preserve's shallow soils support wet meadows, Oregon white oak-madrone woodlands, vernal and permanent ponds, and even a stand of quaking aspen. The trail utilizes boardwalks, which can be slippery during the spring. There are also some sections which can be quite muddy, so hiking (or rubber) boots are strongly recommended. If you visit, PLEASE stay on the trail and do not pick any wildflowers!
