Managing the Impacts of Passenger-Only Ferries on Southern Resident Killer Whales

Abstract

This thesis examines the impact of passenger-only ferries (POFs) on Puget Sound's endangered Southern Resident Killer Whale (SRKW) population, exploring regulatory gaps, analyzing relevant case studies, and proposing management strategies to mitigate adverse effects. Through qualitative policy analysis, literature review, and elite stakeholder interviews, it identifies the compounding threats posed by vessel traffic to SRKW conservation. Key findings underscore the urgency of addressing vessel-related disturbances, collision risks, and noise pollution to ensure the long-term viability of SRKW. Recommendations consider a multifaceted approach, including establishing voluntary speed reduction zones, deploying real-time monitoring technologies, and fostering multi-agency collaboration to enact effective best management practices tailored to SRKW conservation needs. The analysis underscores the importance of ongoing cooperation, coordination, and communication among managers and stakeholders to navigate uncertainties and achieve meaningful conservation outcomes.
