Human-wildlife conflicts (HWC) pose a growing threat to biodiversity worldwide and solutions can be as sound as the understanding of the HWC itself. Conservation biologists therefore must carefully examine their local situations to inform on which approach and strategies may be best. In this context, Mauritius implemented what may be the first mass-culls of an already threatened native species when it culled the flying fox (Pteropus niger) in 2015 and 2016 to try increase fruit producers' profits. Although the Red List category of the species consequently worsened to 'Endangered' and fruit production dropped substantially, a third mass-cull was decided in 2018. A critical analysis is important to draw lessons that may help to prevent recurrences particularly that HWC involving Pteropus spp. are common and set to worsen. We synthesized the best literature available locally and also elsewhere in relevant situations, to critically appraise the setting, nature, timeline of events and outcome of both completed mass-culling campaigns to explore why and how they happened so as to help towards devising better approaches to such conflicts. The idea to cull P. niger originated around 2002 and a small cull was done in 2006. The first mass-cull started immediately after Mauritius' biodiversity protection law was weakened in 2015 primarily to legalize culls of threatened native species, but still breached the law in place then. The 2016 masscull was recommended in line with the law, but was not evidence-based and consequently did not result in improved profits of fruit producers. Appeals supported by best scientific evidence from local and international organizations and conservationists to the effect that culls will not increase fruit production, but instead further endanger the species, were ignored. To forestall recurrences here and elsewhere, it matters to recognize their precursor signs and the conditions that favoured them including why the mass-culls were not stopped. The events provide a rare opportunity to explore the strategy that was used by conservationists and open the way to propose impactful alternatives or additional actions instead. The situation also exemplifies an eroding commitment towards biodiversity conservation, eased by withdrawal from evidence-based policy that suit short term goals of election cycles at the expense of longer term environmental interests.
