In the northern mountains bordering Russia, everyone knew the spry Chinese man as a skilled and ruthless hunter — the kind who once killed a mother black bear as her cubs looked on. But instead of stalking the woods for prey, Liang Fengen now roams the hills without a rifle, working as a ranger to save the area’s endangered Siberian tiger population and protect other wildlife. “When I think about what I used to do, it seems so cruel,” said Liang, 61, who lives in a small house at the foot of the mountains in northeast Heilongjiang province. Liang’s conversion is the result of efforts by nonprofits like the World Wildlife Fund (WWF) and Wildlife Conservation Society, which are harnessing the knowledge of local poachers to rescue Siberian (also known as Amur) tigers from extinction. At the crack of dawn every morning, the expert tracker patrols the forested area by foot in search of data for conservation research: a tiger print here, some wild boar faeces there. The plight of the world’s largest cats is reflected in red banners along the trails leading to the dense woods which proclaim: “Siberian tigers are mankind’s friends.” About 540 are estimated to exist in the wild in a huge are straddling Russia, China and possibly North Korea, having made a comeback from the brink of extinction in the 1940s, when only around 40 Amurs were left, according to WWF. Their biggest threat is humans — both those who poach the tigers to sell their parts on the black market and those who illegally hunt their prey. While Liang has never seen a Siberian tiger — his targets were wild boars and black bears — he says he was indifferent to their plight, and even more so to how his own hunting contributed to the depletion of their food sources. “I thought of animals as a prize to be captured,” Liang said, “until I slowly had a change of heart.” Liang ascends the wooded mountains wearing a full camouflage outfit, complete with cloth strips wrapped tightly around his ankles to keep water out. In the winter, he braves minus 30-degree Celsius (minus 22 Fahrenheit) temperatures. The ranger collects Siberian tiger waste samples for DNA population tracking and uses a GPS device to transmit the coordinates of paw prints and deer carcasses — evidence of paths the tigers have travelled. It is all familiar terrain for Liang, who traversed the mountains as a precocious kid killing for sport and survival. Even while food shortages plagued the country during Chairman Mao Zedong’s rule, Liang’s family always had enough to eat because he and his father would bring home wild boars. “It’s known around the country that Liang was ever the practiced poacher,” said Jin Yongchao, an officer in WWF’s northeast China office. “He has influenced many others.” Some 30 Heilongjiang hunters have traded in their hunting rifles for ranger uniforms, Jin said. Working in conservation did not always come naturally to Liang. After he was recruited in 2004 to become a ranger for Suiyang’s forestry bureau, he surreptitiously continued hunting after dark. “It was a hard habit to kick,” said Liang, who finally stopped more than a decade ago. Now, he said, “as long as my body allows and as long as the forestry bureau needs me, I will continue to protect the tigers with my whole heart and soul.” While Chinese rangers and conservationists work to increase the Siberian tigers’ population in the wild, the country also hosts about 200 captive tiger breeding centres, but many have been embroiled in controversy. On a recent afternoon at the Hengdaohezi Siberian Tiger Park, a duck dangled helplessly from a zip-line above an artificial pond as hungry tigers circled around it. When a mechanical harness abruptly dropped the duck into the water, the tigers surrounded the bird as it splashed frantically until disappearing between one of their jaws. The feeding, a common form of entertainment at Chinese tiger breeding centres, was witnessed by a group of excited smartphone camera-flashing visitors on a mesh-enclosed platform.
