Habitat-loss due to repeated seasonal forest fires.
Direct persecution of leopards by local villagers living in the leopard range.
Genetic impoverishment due to low numbers.
Depletion of wildlife resources by Chinese that (illegally) cross the Russian border in the leopard range.
Depletion of prey by over-hunting and poaching by local villagers as well as "weekend" hunters from the close-by cities of Vladivostok and Ussurisk.
Unwillingness of prosecutors and judges to bring justice to poachers. Arrested poachers who illegally killed ungulates usually receive relatively small fines. Their rifle is returned to them after this fine has been paid.
Too few people, even in Primorye, are aware of the existence of Amur leopards, and this results in a lack of local and international support for its conservation. However, thanks to intensive education and media campaigns, awareness has much improved in recent years.
