Although numbers are small, previous estimates inwards Russian Federation were fifty-fifty less, ranging from 25 to 50 individuals. However, those surveys, based on tracks left inwards the snow, were extremely hard to translate due to the unclear human relationship betwixt numbers of tracks together with let out of individuals. With photographic goggle box camera traps, each private tin flaming hold out identified yesteryear its unique spot pattern, providing a much to a greater extent than precise estimate.
Combining information from both countries increased precision of the estimate, together with provided greater accuracy. Surprisingly, virtually one-third of the leopards were photographed on both sides of the Sino-Russian border.
Anya Vitkalova, a biologist at Land of the Leopard National Park inwards Russia, together with ane of the ii Pb authors of the publication said: "We knew that leopards moved across the border, but entirely yesteryear combining information were nosotros able to sympathise how much displace in that location actually is."
Despite the movement, in that location were differences inwards population dynamics inwards Russian Federation versus China. Leopards are currently recolonizing habitat inwards Red People's Republic of China yesteryear dispersing from the Russian side, where leopard numbers seem to hold out to a greater extent than or less the maximum that tin flaming hold out supported.
Because of these transboundary movements of leopards, only adding results from both sides would convey greatly exaggerated the estimate.
Dale Miquelle, a co-author together with Tiger Program Coordinator for the Wildlife Conservation Society noted: "This showtime rigorous gauge of the global population of the Amur leopard represents an splendid event of the value of international collaboration. The trust together with goodwill generated yesteryear this articulation attempt out lays the foundation for time to come transboundary conservation actions."
