Volunteers pull thistle at Thomas Preserve — part of Iceberg Point on Lopez Island. Keeping invasive thistles in check can help increasingly rare native prairies like this thrive. Want to lend a hand next time? Join a work party to help sensitive and scenic lands flourish (sjpt.org/events).

San Juan Preservation Trust

An Island Marble butterfly appeared two weeks ago at Frazer Homestead Preserve, the first butterfly in many years to venture beyond American Camp — the last remaining Island Marble colony in the San Juans. While we are busy gathering data and will have exciting news to share soon, we want to highlight these photos recalling the four years of science, hard work and hope that led to this exciting moment.

Creating conditions that help new colonies flourish is necessary to the survival of one of the rarest butterflies on earth. That’s why, for four years, Preservation Trust staff and conservation partners have worked diligently to cultivate new island marble habitat on protected lands. This ongoing project is a labor of love in our effort to help recover this vulnerable species.

Special thanks to US Fish and Wildlife, Washington Department of Fish and Wildlife, Washington Conservation Corps, San Juan County Land Bank, San Juan Islands Youth Conservation Corps, Spring Street International School, Preservation Trust volunteers, supporters and, of course, our dogged stewardship manager, Kathleen Foley for your dedication to this project.San Juan Preservation Trust is working to create habitat patches to support the endemic Island Marble Butterfly on SJPT's Sundstrom Farm Preserve and Phelps Preserve, and on the Land Bank's Frazer Preserves, all located on San Juan Island. The patches will be planted with all the plants the butterfly needs and are fenced from deer and cattle so that the butterfly can live out its entire life cycle.
