This study is the first to provide data on the extent of illegal hunting practices in Jordan using posts on social media. During January 2015–January 2016 photographs from seven hunter groups on Facebook recorded the killing of 4,707 native animals of 59 species, of which birds constituted the majority, followed by mammals and reptiles. Flouting of Jordanian laws was widespread, with daily bag limits exceeded on many occasions, and in the case of chukar partridge Alectoris chukar, the most popular quarry, some hunters exceeded the limit by 3,000%. Of even greater concern, a total of 34 species with special protection under Jordanian law were killed, and the hunting of large mammals, especially ibex Capra nubiana and gazelles (Gazella spp.), with already depleted populations, was particularly excessive. It also appeared that a significant number of gazelles were shot by unlicensed hunters from Arabian Gulf countries. Overall, the survey indicates an alarming picture of overhunting of threatened species and ineffective enforcement of hunting laws, despite the efforts of key government and voluntary agencies. We recommend urgent action to address the causes of the problem and to improve the management of hunting through better collaboration, mobilization of resources and awareness raising.
