研究人员在加州北部斯科特河谷采取了一项创新的栖息地恢复措施。1斯科特河流域委员会于2015年在Sugar Creek支流上建造了两座人工坝，随后在2018年于French Creek支流上建造了更多人工坝。1这些人工设施创造了约9000平方米的新湿地栖息地，可容纳8500多条年幼鲑鱼。1
French Creek中银鲑鱼幼鱼的存活率从8%提升至60%。1两年后，返回斯科特河的鲑鱼数量超过了研究中监测的任何其他河流。1
Researchers in California's Scott River Valley have turned to an unconventional conservation strategy to restore lost wetland habitats and revive struggling salmon populations. The Scott River Watershed Commission constructed artificial beaver dams in the region's tributaries, beginning with two installations on Sugar Creek in 20151 and expanding to French Creek with additional structures in 20181.
The engineered dams proved remarkably effective at creating new habitat for young salmon. The structures generated approximately 9,000 square meters of new wetland area capable of supporting more than 8,500 juvenile coho salmon1. Most significantly, the intervention produced a dramatic improvement in survival rates: juvenile coho salmon in French Creek experienced a surge from 8% survival to 60%1. Within two years of the dam construction, the number of salmon returning to the Scott River exceeded that of any other river monitored in the research study1.
