Tataka and Mt. Yushan in altitude 3,952m, which is the highest mountain of Taiwan and East Asia, is the most important recreation area of Yushan National Park. It has the vulnerable alpine ecosystem threatened by.global warming and heavy recreational pressure. We started camera trapping at Tatachia from 2009 April and.extended to Mt. Yushan trail from 2010. We deployed camera trapping with extra effort around the Paiyun mountain lodge in 3 different distances from the lodge assess its influences of backpacker activities rashes on the mammals. In addition, camera traps were placed at Mt. Yushan trail to record the activity and occurrences of hikers. Monitoring of hiker activity revealed the diel activity patterns. Sambar deer (Rusa unicolor) had significantly higher nocturnal activities near trails. Moreover, Formosan serow (Capricornis swinhoei) and sambar deer tended to avoid hiker peak hours at areas closer to trails. Sambar deer, yellow-thraoted marten (Martes flavigula), Siberian weasel (Mustela sibirica), squirrels and rodents except Taiwan field voles (Microtus kikuchii) has the highest occurrence rates near the Paiyun lodge. It is very likely sambar deer and rodents were attracted by the hiker trash and more minerals from human urines. And predators follow prey to exhibit high occurrence rates nearby the lodge. But the Taiwan field voles are plant eaters and don't benefit from human food. They, incontrast, face higher predation pressure ad occurred the least frequently near the lodge. It is recommended to.avoid.leaving.concentrated trash, food remains, or human excrement near the lodge. In summary, it is necessary to further monitor and assess the impacts of human activities to these vulnerable larger mammals and establish sound management for human activities and conservation of wildlife.
