The leopard was photographed in the Hunchun Amur Tiger National Nature Reserve in Jilin Province, the New York-based Wildlife Conservation Society reported Wednesday.
Provincial officials recently announced the results of a survey showing an estimated 8 to 11 leopards are living in the province.
Most of the world's remaining Amur leopards live across the border in Russia where camera traps photographed 29 leopards last winter in a portion of the newly created Land of the Leopard National Park.
A number of the cameras were donated by the WCS in support of Russian-Chinese transboundary conservation of Amur leopards and tigers.
Estimates of the total number of surviving Amur leopards have hovered around 30 since the mid-1970s, but the combined Russian and Chinese photo evidence and surveys suggest leopard numbers may be rising to 40 or more, the WCS said.
