Ferns are distinctive and popular for the exotic texture they add to vegetation. Join Friends of the Dunes and Naturalist Carol Ralph for a Ferns of the Dunes Walk at the Lanphere Dunes Unit of the Humboldt Bay National Wildlife Refuge. Carol will introduce eight species of common ferns during an easy walk along the riparian edge of the dunes, while discussing 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.
