At the Lanphere Dunes Unit of the Humboldt Bay National Wildlife Refuge, naturalist Carol Ralph will introduce eight species of common ferns during an easy walk of about 1/4 mile along the riparian edge of the dunes and discuss some of the amazing aspects of fern life. Bring a hand lens if you have one and be prepared for mosquitoes. Meet at Pacific Union School, 3001 Janes Road in Arcata and carpool to the protected site. Co-sponsored by the California Native Plant Society and Friends of the Dunes. Please reserve your space by contacting Friends of the Dunes.
