III. Reading ComprehensionThe South China tiger is the most endangered tiger subspecies. Due tohabitat loss and fragmentation, tiger eradication campaigns, uncontrolledhunting, and human invasion into tiger habitat, the South China tiger sufferedmajor population declines during the last century. Listed as Critically   Endangered by the International Union for Conservation of Nature (IUCN), ithas not been directly observed in its habitat since 1970, suggesting it ispossibly extinct in the wild. Restoration of wild populations within thesubspecies’ historical range will therefore require reintroduction efforts.The IUCN indicates that reintroduced animals can be either from acaptive or wild source. However, the use of wild-caught individuals isgenerally preferred, as reintroductions using captive animals are less likely tobe successful. Nonetheless, for the South China tiger, the only animalsavailable for reintroduction are from captivity.When animals are in captivity for generations, their behavior mayexperience artificial selection to adapt to their captive environment. Theseadaptations, although beneficial to captivity, can compromise their survival inthe wild, where deficiencies can be seen in hunting, social interactions,breeding and nesting, and so on. However, these animals can be behaviorallyconditioned to develop those skills that might have been lost during captivity.In fact, pre-release conditioning has modified behaviors in several mammalspecies in ways assumed to be beneficial for survival.To breed and prepare captive-born South China tigers for reintroduction,Save China’s Tigers, a charity in collaboration with the Chinese State ForestryAdministration (SFA), relocated four South China tiger cubs from Chinesezoos to a private captive facility in South Africa in 2003 and 2004. SouthAfrica was chosen to establish the breeding facility because land, free-rangingprey, and wildlife expertise were available. Tigers at the facility wereprovided opportunities under semi-wild conditions to acquire hunting andother survival skills to prepare them for reintroduction in China. Despiteconcerns relating to the ex situ nature of the project by some in theconservation community, the SFA recognized the project as the first practicalstep towards the restoration of South China tigers to the wild, and consideredit consistent with IUCN guidelines for reintroductions since China lacked thenecessary habitat, expertise and infrastructure to conduct the project in situ.Recently, Chinese authorities and international organizations have identified  existing protected areas of sufficient size within the subspecies’ historic rangeas potential sites that could be suitable for habitat restoration andreintroduction of the South China tiger.
