Island Spotted Skunk Conservation Plan
The Island Spotted Skunk Conservation Plan was developed following discussion by members of the nascent Island Spotted Skunk Working Group at a meeting in Ventura, California on January 16th and 17th, 2020. This document is adapted from a similar plan developed by the Eastern Spotted Skunk Cooperative Study Group. In 2021 and 2022, the plan was updated to incorporate new research and findings from the past year of skunk work.
Primary goals of the document include: 1) to summarize what is known about the island spotted skunk and its current status; and 2) to identify the knowledge gaps that should be the target of future research, monitoring, and management actions to advance island spotted skunk conservation.
