鑑於長期監測對於野生動物經營管理的重要,本研究於2004年利用痕跡調查法和自動相機照相系統於玉山國家公園楠溪林道地區進行動物族群之監測,以期瞭解該區較大型哺乳動物之相對豐富度及分布現況,並與王穎1995~1996年之調查結果比較,以評估該區動物族群於此期間的變動。研究總共記錄20種非飛行性的哺乳動物,包括瀕臨絕種保育類台灣黑熊、前期未曾發現的麝香貓及五種囓齒類動物,但本研究則未發現前期曾記錄之台灣野兔。初步比較結果顯示,該地常見的中大型哺乳動物的豐富度和分布似乎有增加的趨勢。本研究建議長期監測野生動物族群變化應使用簡便且系統性、一致性、標準化的方法。
Considering the importance of continuous monitoring programs for wildlife management, we adopted sign count and camera trapping methods to evaluate the abundances and distributions of large mammals along the Nanzihshian logging road of Yushan National Park, south-central Taiwan in 2004. To monitor changes in mammal populations over time, we compared my data with a study conducted in the same area by Prof. Ying Wang in 1995~1996. We identified 20 species of mammals, including the endangered Formosan black bear (Ursus thibetanus formosanus), small Chinese civet (Viverricula indica), and 5 rodent species not recorded in the previous study, but we did not record the once-occurring Formosan hare (Lepus sinensis). Our preliminary data suggest that the abundances and distributions of locally common larger mammals seemed to have increased and expanded. An easy, systematic, consistent, and standardized method for long-term monitoring pro - grams of wildlife population changes is suggested.
