Summary

The current study was designed to provide critical information for resource managers (specifically the Bureau of Ocean Energy Management, henceforth BOEM, and the U.S. Fish and Wildlife Service, henceforth USFWS) about the spatial ecology, population status, and potential population threats to sea otters in Santa Barbara Channel, with particular reference to exposure to manmade structures and sources of oil and natural gas. Our four primary research objectives were: 1. Determine the extent of movements and spatial use patterns by sea otters along the southern California coast 2. Identify important sea otter resting and foraging areas adjacent to manmade structures 3. Assess sea otter distribution, behavior and habitat selection in [...]

Purpose

The study was designed to provide critical information for resource managers (specifically the Bureau of Ocean Energy Management, henceforth BOEM, and the U.S. Fish and Wildlife Service, henceforth USFWS) about the spatial ecology, population status, and potential population threats to sea otters in Santa Barbara Channel, with particular reference to exposure to manmade structures and sources of oil and natural gas. In addition to investigating the potential impacts of natural oil seeps and manmade structures on sea otters in the Santa Barbara Channel, conducting a long-term monitoring study at the extreme southern edge this species’ range provided us the opportunity to examine a variety of biological and ecological parameters that are relevant to sea otters and nearshore ecosystems as a whole. In particular, by using a comparative approach (comparing various metrics between sea otters in Santa Barbara Channel and sea otters in other locations within the range), we can determine the status of the population in this region with respect to prey resources, and identify any natural and/or anthropogenic threats to population recovery.
