The last stable population of the endangered Silverspot Butterfly in the world lives here in Tillamook County, on our own Mount Hebo. An audience numbering more than fifty from as far away as Eugene gathered at The Pelican Pub and Brewery in Pacific City Tuesday evening, February 19 for a presentation on the Silverspot. The event, scheduled to coincide with the regular meeting of the Nestucca Watersheds Council, was a joint effort between the Council and Hebo Stewardship Group for community education and outreach.
According to presenters Anne Walker and Michelle Dragoo scientists observed the first dangerous decrease in population for Silverspot Butterfly after an especially wet, cold spring in 1993. The Silverspot could once be found all along the Pacific coast from northern California clear into central Washington. Today there are only five known colonies of the endangered insect, and the only stable population lives on Mount Hebo. Less stable colonies survive at Cascade Head, Lake Earl, Ray’s Point, and Rock Creek.
