Book excerpt: In response to a request,in 2009, by the Lake Erie Island Chapter of the Black Swamp Conservancy, the Flora of the Erie Islands: Its Origin, History and Change is published to assist their conservation activities and programs. Completed in 1976 and, in 1979, scheduled to be although not published, xerographic copies of the manuscript were provided to researchers studying the islands' flora. As a result, the unpublished manuscript was widely cited in publications during the past 35 years and,in published form, remains a primary research resource concerning the flora of the Erie Archipelago.
