Managing Invasive Mammals to Conserve Globally Threatened Seabirds in a Changing Climate

Invasive mammals are an ongoing threat at many seabird breeding locations, while impacts from climate change can occur over broad time-scales. Combining management strategies for invasive mammal and climate change impacts is important for mitigating current threats and maximizing seabird survival into the future. We assessed all 713 islands with threatened seabirds for conservation importance, immediate benefits of three invasive mammal management actions, and risk of climate-change related flooding. Preventing invasions on the 397 islands without invasive mammals would benefit 72 seabird species. Invasive mammal eradication or localized action was highlighted on 249 and 67 islands, benefiting 71 and 46 seabird species, respectively. The long-term risk of flooding on the 713 islands was low (69%). Low-risk islands were concentrated where eradications or localized action were highlighted (75% and 100% of islands, respectively). These results inform management feasibility assessments and highlight rare opportunities to make significant contributions to seabird conservation. This article is protected by copyright.
