Wildlife experts have expressed optimism over an increase in the population of rare Amur tigers and believe that endangered species might be restored.

A new video footage of Amur tigers in the wild in China was captured in the Wangqing Nature Reserve. Experts said that the location of the new video shows that the tigers were 30 kilometres from the Russian border indicating that the tigers were raised in China. They expect the endangered species to make a comeback and increase population.

John Barker, Head of India and China Programmes at WWF UK pointed out that the video clearly indicates that the tigers were actually raised in China. The Amur Tiger, which is also popularly known as Siberian Tiger has once again started living and reproducing in China. The video captured by World Wildlife Fund (WWF) camera mounted in the Wangqing Nature Reserve nearly 20 miles from the Russian border.

The video, which was recorded in the previous year, shows a tigress with her playful cubs. It confirms that the cubs were raised in China as they would not have walked 20 miles from the Russian border while they were so young.

"It's confirmation they're re-establishing, they're not just animals coming in and out. We shouldn't get hysterical over one video. There's a long, long road ahead. But the opportunity is there. If the government, civil society and communities can work together, there's no reason there shouldn't be a sustainable population of tigers again in China," said John Barker, Asian programs leader at the WWF.
