Panthera pardus orientalis
Southwest Primorsky Krai, Russia, and adjacent Jilin and Heilongjiang, China
Counted 2022, by Marchenkova and others in Wildlife Letters (released December 2025).

The latest figure for the Amur leopard is about 118 (115 to 121), an estimate with a range, counted in 2022 in Russia only, by Marchenkova and others in Wildlife Letters (released December 2025).
About 118 (115 to 121) Amur leopards lived in Russia's survey area in 2022, and the study reports continued growth there.
How it was counted
The estimate comes from camera traps in the protected areas of southwest Primorsky Krai, Russia, and it counts animals, with a range around the most likely figure. It covers that survey area only: China's share is not included.
A survey estimate with a range, for the Russian survey area only: about 118 animals is the most likely figure, and 115 to 121 is how far either way the true number could sit.
What moves it
Marchenkova and others name the threat of poaching. They also raise, as possibilities only, rising tiger numbers in Land of the Leopard National Park, which may push females with cubs to the park's edges, and ongoing inbreeding and health problems, which may mean fewer cubs.

Camera trap monitoring data are not publicly shared due to the threat of poaching.

Who is helping
Marchenkova and others credit Land of the Leopard National Park (Russia) with federal-level habitat protection over most of the leopard's current range in Russia, uniting and expanding earlier regional protected areas. They also credit anti-poaching work inside the protected area, without naming who carried it out: "With strong antipoaching efforts within the protected area, the population began to gradually recover."
The next count
No date for the next estimate is known as of 12 November 2026. The schedule is irregular (camera traps run every year; robust estimates are published rarely).

The letter
The letter comes once a month, on the first Thursday. It gives what changed on Live Species, one animal up close and the humans figure for contrast.
