Jordan’s mammalian fauna has experienced significant declines due to intensified hunting since the early twentieth century, leading to the extinction of six species and threatening 39% of the remaining species. This research evaluates the evolution of Jordan’s hunting laws across three historical stages – the Ottoman period, the establishment of Jordan and the modern era – highlighting their impacts on mammalian diversity and identifying legislative gaps contributing to species declines. Using Arabic-based legal databases and historical archives, we found that inadequate legal frameworks, political instability, economic pressures and weak enforcement often accelerated species depletion. Notably, the 1957 Hunting Law permitted hunting of vulnerable species with a licence and of predators without a licence, worsening species decline. Although the 1962 Defense Law aimed to protect nature, its expiration hindered progress. The 1966 Hunting Law largely duplicated the 1957 law, perpetuating these problems, and then hunting regulations were absorbed into agricultural law, undermining conservation efforts. Despite these legal shortcomings, Jordan’s modernization vision provides hope for reform, including the potential restoration of the Hunting Law under the Ministry of Environment and incorporating the right to a healthy environment into Jordan’s constitution to help prevent a mass extinction of mammals.
