Implication

Literature review demonstrates high success in invasive rodent eradications on global islands, suggesting funding and social support are now the primary barriers.

Key Points

To assess the historical efficacy and current state of global island invasive rodent eradication campaigns and identify strategic priorities to enhance future conservation outcomes.
Reviewed global literature on island rodent eradications covering 387 total campaigns across 284 islands totaling 47,628 hectares.
Evaluated campaign outcomes, toxicant choices, distribution modalities (bait stations, hand broadcast, aerial broadcast), and nontarget vertebrate impacts.
Identified 332 successful eradications, 35 failures, and 20 campaigns with unknown outcomes across 284 islands.
Brodifacoum was applied in 71% of eradication campaigns and across 91% of treated land area, while aerial broadcasting accounted for 76% of all treated area.
Nontarget native vertebrate mortality occurred but populations routinely recovered to pre-eradication densities or higher, indicating island size is no longer the primary operational barrier.
