海獭返回加州中部，通过恢复螃蟹饮食来减轻侵蚀，从而促进生态系统的改善。 Sea otter return to central California spurs ecosystem improvement via abating erosion through crab diet restoration.
《自然》杂志的一项研究发现，海獭返回加州中部对当地生态系统产生了巨大影响，防止了侵蚀并改善了整体景观健康。 A study in Nature has found that the return of sea otters to central California has had a dramatic effect on the local ecosystem, preventing erosion and improving overall landscape health. 在濒临灭绝的毛皮遭到猎杀后，水獭已经开始恢复并返回埃尔克霍恩沼泽等沿海栖息地。 After being hunted for their fur close to extinction, otters have started to recover and return to coastal habitats such as Elkhorn Slough. 它们的饮食包括穴居蟹，有助于对抗侵蚀。 Their diet, which includes burrowing crabs, has aided in combating erosion. 这标志着保护工作取得了重大成功，展示了动物种群恢复生态系统的潜力。 This marks a significant success in conservation efforts, demonstrating the potential for animal populations to restore ecosystems.
