Hunting is a major driver of biodiversity loss, but a systematic large-scale estimate of hunting-induced defaunation is lacking. We synthesized 176 studies to quantify huntinginduced declines of mammal and bird populations across the tropics. Bird and mammal abundances declined by 58% (25 – 76 %) and by 83% (72 – 90%) in hunted compared to unhunted areas. Bird and mammal populations were depleted within 7 and 40 km from hunters’ access points (roads and settlements). Additionally, hunting pressure was higher in areas with better accessibility to major towns where wild meat could be traded.
