The 16th International Tiger Day promotional event was held on July 29 at the Dongning science education center of Northeast China Tiger and Leopard National Park in Heilongjiang province, showcasing achievements from the park's first five years since its official establishment.

Nearly 10,000 participants, including officials, experts, and representatives from domestic and international organizations, attended the event. They included the National Forestry and Grassland Administration, Russia's Land of the Leopard National Park, the World Wildlife Fund, and the Natural Resources Defense Council.

At the event, Zhang Dehui, deputy director-general of the Department of Wildlife Conservation under the National Forestry and Grassland Administration, said the establishment of the national park has fundamentally addressed habitat fragmentation and fragmented management by promoting integrated ecosystem conservation. As a result, populations of wild Amur tigers and Amur leopards have continued to recover.

According to the park's management bureau, the number of wild Amur tigers has increased from 27 before the pilot program to 72, and the Amur leopard population has grown from 42 to 115 over the past five years.

The park's management bureau and Russia's Land of the Leopard National Park also released the latest joint monitoring results. At least 147 wild Amur tigers and 223 wild Amur leopards were recorded across the connected protected areas in China and Russia.

The event also marked the official opening of the Dongning science education center, China's first immersive ecological education facility designed around animals' sensory perspectives.
