China and Russia jointly identify tigers and leopards crossing their border
China and Russia are working together to track Amur tigers and leopards that move across their border.
The animals live in and around the Northeast China Tiger and Leopard National Park, which borders Russia’s Land of the Leopard National Park.
Since 2025, the two countries have used the same method to identify individual animals by comparing their coat patterns.
This helps them understand population size, age, breeding and movement across the border.
A joint count confirmed that 21 tigers and 27 leopards regularly cross between the countries.
The partners have also opened 290 passages through border fences so wildlife can move between habitats.
They plan to keep sharing monitoring data and updating population information to support conservation.
The work matters because the animals’ ranges cross a national border, so protecting them requires both countries to coordinate.
