From 2006 through 2009, we are collaborating with the California Department of Fish and Game and the U.S. Fish and Wildlife Service on a project involving the federally threatened species, Oregon Silverspot Butterfly, near Lake Earl in Del Norte County. We have been conducting semi-weekly flight surveys for butterflies, characterizing vegetation along survey transects and planned habitat manipulation plots, and have begun behavioral observations of ovipositing butterflies. In 2008, we will begin experimental habitat manipulations with the host plant, early blue violet.
