Abstract
The principal pollutant threats to Marbled Murrelets are chlorinated organic effluent discharges from chlorine bleach pulp mills located in California, Washington, and British Columbia. The distribution of murrelets away from riverine input of agricultural chemicals reduces the threat from these pollutants. Plastic ingestion does not appear to pose a serious threat to murrelets, as it does for other species of small alcids. Significant threats from oil pollution are present because of heavy oil tanker, commercial shipping, and barge traffic along the Pacific coast. Commercial fishing threats have been significantly reduced in California, Oregon, and Washington because of regulation and banning of gill-net fisheries, but thousands of murrelets are still killed annually in Alaska.
