CRISPR-based gene drives offer solutions for controlling invasive species, but their feasibility varies among different sized species.
CRISPR-based gene drives offer novel solutions for controlling invasive alien species, which could ulti-mately extend eradication efforts to continental scales. Gene drives for suppressing invasive alien verte-brates are now under development. Using a landscape-scale individual-based model, we present the first estimates of times to eradication for long-lived alien mammals. We show that demography and life-history traits interact to determine the scalability of gene drives for vertebrate pest eradication. Notably, optimism around eradicating smaller-bodied pests (rodents and rabbits) with gene-drive technologies does not easily translate into eradication of larger-bodied alien species (cats and foxes).
