Guardians of China's tiger and leopard park

The park, in collaboration with relevant technical units, developed a high-tech surveillance system, providing real-time monitoring of wildlife. The system integrates modern communication, artificial intelligence and cloud computing, helping capture images of Siberian tigers and Amur leopards, according to the park.

It also plays an important role in monitoring natural resources, forest fire prevention efforts and human-tiger conflict alerts.

To date, nearly 20,000 wireless infrared cameras have been installed across the 1.4 million-hectare park, covering the main distribution areas of tigers and leopards.

Data from these cameras is transmitted to various management centers, where it is transcoded and processed using neural network technology.

Through an AI algorithm platform, information on various species can be identified and recorded.

Hao, who has worked his way up from a forest farm, is well acquainted with the growth of vegetation in the forest and the habits of wildlife in the mountains. "In previous years, clearing hunting traps was a major priority in our work, especially in autumn when fallen leaves made them harder to spot," he said.

"In recent years, as villagers' awareness of ecological protection has increased and hunting traps have become increasingly rare, our focus has shifted to maintaining infrared camera equipment and collecting biological samples."

With the establishment of the national park, the number of wild animals in the mountains and forests has increased gradually.
