Anderson’s Sword-Fern, also called Vancouver Holly Fern, is found in deep forested areas. A fern and a member of the Dryopteridaceae Family, it grows by Kiosk 08. Pilchuck Learning Center’s sponsored Western Washington State University SAM Project extinction possibility is slight; found only “here and there” in Cascadia. If you visit the URL’s below,
note how unique its areas are. Botanists might call it an “regional endemic,” though Anderson’s distribution is a bit broader than that. Also read the intriguing name journey in the American Fern Journal cited below (bet you didn’t know there was an American Fern Journal, part of the American Fern Society with 500 members, going strong since 1905). We quote: “named after Walter Birney Anderson (1856-1944), Collector and Government Inspector of Indian Orchards.” Canada had a highly trained government scientist/employee surveying INDIAN ORCHARDS (collected August 2, 1912) on Vancouver Island. Exactly how many orchards/forest groves were there on the Island? What size of Indigenous populace would it indicate? A government scientist who studied Native American forest groves … he and the groves now long forgotten
