Island Marble Butterfly

The Island Marble Butterfly is recognized as one of the most endangered butterflies in the world, with only about 200 known to be living in a single area on San Juan Island. These butterflies are being supported through the planting and protection of habitat areas on San Juan Island, in partnership with US Fish and Wildlife, Washington Department of Fish and Wildlife, National Parks Service, Bureau of Land Management, San Juan Preservation Trust, San Juan County Land Bank, San Juan Islands Conservation District, and several private landowners.

The Conservation District is working directly with landowners to establish and maintain habitat that is known to support Island Marble reproduction. In the coming seasons, our Youth Conservation Corps will be having a hand in restoring this beautiful butterfly by tending to the habitat plots, looking for signs of reproduction and new butterflies, and reporting to the community on findings.
