Hunting
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. Mammal population densities were lower outside protected areas, particularly due to commercial hunting. Strategies to sustainably manage wild meat hunting in both protected and unprotected tropical ecosystems are urgently needed to avoid further defaunation.
