Pacific Northwest Butterflies

The Xerces Society has worked extensively on a handful of butterflies that inhabit prairies of the Pacific Northwest – namely the mardon skipper, the island marble and taylor’s checkerspot. These species are nearing extinction because less than one percent of their prairie habitat still remains. Agricultural and urban development, encroachment of trees, and spread of invasive plants all threaten the native grasslands in which these butterflies are found. In addition, pesticide use, recreational activities and grazing pose a direct threat to the butterflies themselves. We continue to use a combined approach of applied research, advocacy, outreach, and collaboration with state and federal agencies to work toward the conservation of these species.

The Xerces Society is also involved in the conservation of a number of other at-risk Pacific Northwest butterflies, through workgroup involvement, assistance with conservation strategies, or developing status reviews.
