COSEWIC rapid review of classification Preface Status re-examined and confirmed in May 2000, April 2010, and December 2022. Rescue is unlikely, as the closest population on San Juan Island is 15 km over open ocean. These surveys were informed by recent advances in understanding of the species ecology from studies of the small extant population on San Juan Island in Washington State. This area has been well surveyed for butterflies, with targeted surveys from 2001 to 2008. Historically, the species occurred on southern Vancouver Island and adjacent Gulf Islands. Reason for designation: This butterfly has not been found in Canada since 1908, and availability of suitable habitat is limited. Scientific name: Euchloe ausonides insulanus This report was overseen and edited by Jennifer Heron, Co-chair of the COSEWIC Arthropods Specialist Subcommittee.Į-mail: disponible en français sous le titre Examen rapide de la classification du COSEPAC sur le Marbré insulaire ( Euchloe ausonides insulanus) au Canada.ĬOSEWIC assessment summary Assessment summary – December 2022 McCorquodale for writing the rapid review of classification on the Island Marble, Euchloe ausonides insulanus, in Canada, prepared under contract with Environment and Climate Change Canada.

The following is a summary of the relevant information.ĬOSEWIC Rapid Review of Classification are working documents used in assigning the status of wildlife species suspected of being at risk in Canada. Readily available information from the previous status report or status appraisal summary, recovery documents, recovery teams, jurisdictions, conservation data centres, and species experts is initially reviewed by the relevant Species Specialist Subcommittees before being reviewed by COSEWIC. The rapid review of classification process is used by COSEWIC for wildlife species that have not changed status since the previous COSEWIC assessment.
