The primary goal of the Southern Resident Killer Whale (SRKW) Sightings Dashboard is to provide a resource for individuals and organizations to determine appropriate marine mammal protections for SRKWs when constructing projects throughout the Puget Sound. Specifically, in conjunction with the known action area of a project, it can help determine whether a marine mammal monitoring plan (MMMP) is needed that includes orcas. The National Marine Fisheries Service uses this tool to determine necessary MMMPs for Endangered Species Act consultations, including projects under the Salish Sea Nearshore Programmatic Biological Opinion.
