San Francisco Bay could become the new home to extinction-threatened sea otters, according to a recent report published in PeerJ. Although the bay is located in the middle of a major urban area, it may still offer a suitable environment for the otters. While most parts of the bay may not suit wild animals, some sections manage to meet the requirements for a conducive sea otter habitat. Sea otters have struggled to grow in numbers due to increased shark attacks along California’s central coast, which has been their home for decades. In the early 1900s, people hunted otters to the brink of extinction due to their luxury fur. However, protection measures enacted in 1911 helped the otter population grow to about 3,000 by 2020. Unfortunately, their population seems to have stagnated over the past decade due to increased shark attacks. To help the otter population continue growing, wildlife managers have looked at alternative residences in pockets of coastal waters. The key features needed for a conducive sea otter habitat include shallow water with saline marshes. According to Jane Rudebusch, the lead author of the study and a spatial ecologist at San Francisco State University’s Estuary & Ocean Science Center, […]
