RT Journal Article SR Electronic T1 Iran’s roads: mitigating the most serious threat to the critically endangered Asiatic cheetah Acinonyx jubatus venaticus JF bioRxiv FD Cold Spring Harbor Laboratory SP 230581 DO 10.1101/230581 A1 Jamshid Parchizadeh A1 Maria Gatta A1 Roberta Bencini A1 Ali Turk Qashqaei A1 Mohammad Ali Adibi A1 Samual T. Williams YR 2017 UL http://biorxiv.org/content/early/2017/12/09/230581.abstract AB Wildlife-vehicle collisions are an important cause of mortality for many species, and the number of collisions is expected to grow rapidly as the global road network quickly expands over the next few decades. Wildlife-vehicle collisions also have the potential to be extremely detrimental to small wildlife populations, such as the critically endangered Asiatic cheetah (Acinonyx jubatus venaticus), with only 43 individuals remaining in the wild. We assessed the spatial distribution of road mortalities between 2004 and 2016 to identify roadkill hotspots involving Asiatic cheetahs in Iran using network kernel density estimation. A total of sixteen cheetah fatalities due to wildlife-vehicle collisions were recorded, and we identified six road fragments as roadkill hotspots. Efforts to reduce wildlife-cheetah collisions should be targeted in the densest hotspots. We review the options available to achieve this, and we recommend a strategic shift away from the ineffective warning signage currently used, and instead suggest adopting an evidence-based approach focusing on installing wildlife crossing structures in conjunction with fencing in roadkill hotspots. These measures will help to enhance the conservation status of the Asiatic cheetah, as the current high level of mortality of Asiatic cheetahs on Iran’s roads could have potentially dramatic impacts on this critically endangered subspecies.
