Invasive Rodent Eradication on Islands

摘要: Invasive mammals are the greatest threat to island biodiversity and invasive rodents likely responsible for number of extinctions ecosystem changes. Techniques eradicating from islands were developed over 2 decades ago. Since that time there has been a significant development application this conservation tool. We reviewed literature on rodent eradications assess its current state identify actions make it more effective. Worldwide, 332 successful have undertaken; we identified 35 failed 20 campaigns unknown result. eradicated 284 (47,628 ha). With exception two small islands, rodenticides used in all eradication campaigns. Brodifacoum was 71% 91% total area treated. The most frequent rodenticide distribution methods ( least) bait stations, hand broadcasting, aerial broadcasting. Nevertheless, using broadcast made up 76% Mortality native vertebrates due nontarget poisoning documented, but affected species quickly recover pre-eradication population levels or higher. A variety mitigate impacts, applied research can further aid minimizing impacts. Land managers should routinely remove <100 ha lack susceptible poisoning. For larger those require mitigation, expert consultation greater planning effort needed. house mice (Mus musculus), size may no longer be limiting factor eradications; rather, social acceptance funding main challenges. To successful, large-scale integrated with programs improve livelihoods residents, biosecurity, reinvasion response programs.
