The center's 1,000-plus tigers need snow to quench their thirst and wash themselves, but this year's snowfall has been too little to meet their requirements, said Liu Dan, chief engineer of the Siberian Tiger Park in Harbin, the capital of Heilongjiang province.
The Sun Island Snow Expo Park located next to the breeding center has provided about 90 cubic meters of artificial snow for free to help the tigers deal with the mild winter, Liu said.
The artificial snow has also provided visiting tourists with entertainment, as they enjoy watching the tigers play in the snow, Liu added.
Siberian tigers are among the world's rarest species. The population of wild Siberian tigers is estimated to be around 500, most of which live in east Russia and northeast China.
