Purpose of the Proposal and Its Anticipated Effects, Including Any Changes in Existing Rules: The purpose of this rule project is to consider classifying the island marble butterfly as endangered. The proposed change would amend WAC 220-610-010 to include island marble butterfly among the other listed endangered wildlife.
Reasons Supporting Proposal: United States Fish and Wildlife Service recently classified the island marble butterfly as endangered under the Endangered Species Act (ESA). The island marble butterfly exists in a few locations on San Juan Island, a fraction of its former range. WDFW staff issued a report summarizing the current status, distribution, threats, and conservation challenges for the species, and also recommended an endangered species classification. WAC 220-610-110 provides guidance to the agency on recommending an endangered or threatened classification when species are listed as endangered or threatened under ESA.
Rule is not necessitated by federal law, federal or state court decision.
