“…The conflict between humans and wildlife in North America has long been documented in the field of human dimensions of wildlife management (Decker et al 2012), and here, Engeman et al (2018) present diverse examples of wildlife management on inhabited islands of the USA. Wildlife management on islands can also be a trans-boundary issue, and Levin et al (2018) outline complementary examples from the Western Indian Ocean focusing on marine conservation across multiple island jurisdictions.…”

“…Feral Swine, Cayo Costa Island (Engeman et al 2018) . Feral Swine were introduced to Cayo Costa Island (Lee County) in the 1800s by local fishermen as a food source, with more releases occurring in the 1980s.…”

“…Despite the island only having ∼24 residents, there was strong opposition to the eradication effort from residents that resulted in the effort being thwarted (the authors imply that residents likely reintroduced the swine to the island). A second eradication effort appears to have successfully removed all swine from this island (Engeman et al 2018, USDA 2021), although swine populations remain present throughout nearly all of Florida (McClure et al 2018).…”

“…Many non-native bird species are highly regarded by birdwatching enthusiasts and present potential negative impacts that are poorly understood or appear to be benign (Greenlaw et al 2014). In contrast, many of the species targeted for eradication in my review are nuisance species that merit rapid response such as the Feral Swine, Black-tailed Prairie Dogs, and Roofs Rats (Engeman et al 2018, Hardin et al 2014, Witmer et al 2010). The iguanas targeted for removal were so disruptive that residents decided to fund their own removal effort (Avery et al 2014).…”

Species invasions can alter ecosystems, decimate populations of native species, facilitate the spread of infectious diseases, and threaten industries like fisheries and agriculture. Significant resources and financial investments are often directed towards invasive species management (ISM) to prevent future introductions, to remove smaller populations, and to contain expanding populations. While prevention is the most important goal of ISM, focus may shift to removal (eradication) when prevention fails. Eradication attempts are costly and have not been inclusive of all invasive populations. These efforts are inherently difficult because they require an abundance of resources, must be executed before the population expands, can be disrupted by public opposition, and often require years of monitoring to confirm success. Regardless, even failed eradication attempts provide important lessons to potentially improve future eradication efforts. This review of 20 case studies in Florida assesses successful and failed eradication attempts to identify common factors that contributed to each outcome. More than half of the detailed failed eradication attempts either lacked communication from or were outright disrupted by stakeholders. Most successful eradications targeted fish or small mammals and removed <200 individuals. Nearly half of the successful eradications occurred on islands or within isolated bodies of water. Despite the abundance of invasive herpetofauna in Florida, there has yet to be a documented successful eradication effort targeting these species. While many barriers exist to publishing eradication outcomes, future eradication efforts should prioritize documentation to provide guidance to similar efforts. Future research should address the role of media coverage and outreach efforts regarding eradication success, especially efforts targeting charismatic species.

“…Thus, nonnative prey base reductions can augment BTS removal longevity and efficacy where feasible. Moreover, rats can pose substantial hazards to endangered birds (e.g., Buckle and Fenn, 1992), and reducing their populations would also be important for reclaiming land for endangered species reintroductions (Engeman et al, 2018). Reducing nonnative prey where feasible in potential recipient locations for BTS could also enhance attractiveness of mice in traps or DNM in bait stations.…”

a b s t r a c tAfter its inadvertent introduction to Guam, the brown tree snake (Boiga irregularis, BTS) extirpated most of the island's native terrestrial vertebrates, presented a health hazard to small children, and had considerable economic ramifications. Management of BTS is aimed at a number of objectives, the foremost of which has been to deter its dispersal from Guam to other locations. Further objectives include reclaiming areas on Guam as snake-free for reintroduction of native wildlife, to protect small sensitive sites on Guam from BTS intrusion (e.g, power stations, bird nesting sites), to contain and capture stowaway BTS incoming to vulnerable destinations, and to control incipient populations in other areas beyond their native range. A number of control tools have been developed, and the efficacy of each control method depends on the situation to which it is applied. Integration of control methods provides the most efficacious results for all objectives. Here, we outline the different objectives for managing BTS, and the tools and methods available for BTS management. We complete the picture by describing which tools and methods are best suited to accomplish each management objective.Published by Elsevier Ltd.
