    Abstract: 台灣地區人工林為森林生態系之一部分,所佔面積達42萬公頃。陸域脊椎動物在森林生態系的食物網中扮演捕食者與被捕食者的角色,且對於棲地環境之變化非常敏感,極適合作為指標生物及保護傘生物來探討環境變動對生物多樣性所造成之影響。因此了解人工林動態與不同結構對於脊椎動物多樣性的影響,作為人工森林經營管裡重要的參考。本計劃將藉由比較群聚結構及物種組成,探討南投林管處巒大事業區人倫林道人工柳杉林不同疏伐程度,對陸域脊椎動物多樣性的影響。本計劃第一年選定未來做為三種不同疏伐程度(0﹪、25﹪和50﹪)作業的12個樣區,進行脊椎動物多樣性組成調查。本年度成果兩棲類共有6種;爬行動物則記錄5種。在柳杉造林區域裡,鳥種的多樣性較闊葉林區域為低,但在人造林區域的十二個樣區之間,鳥類物種數多樣性則非常的相近(範圍9到15,平均11.42)。自動相機共拍攝到中大型哺乳動物5種;小型食蟲目動物-鼩鼱為人造林下層最顯著之哺乳動物類群。
    Man-made forest ecosystem occupied about 420,000 ha in Taiwan. Terrestrial vertebrate fauna accounts for the dominant of animal diversity in the forest ecosystem, and are important in mediating interactions with predators and preys. Moreover, vertebrates are very sensitive to the conditions of habitats, and therefore they are suitable ecological indicators and as an umbrella species to assess the effects of environmental impacts on biodiversity. Understanding the effects of various strategies for forest restoration on vertebrate biodiversity plays a central role in long-term management of forests in Taiwan. This study aims to investigate the diversity of vertebrates in the Japanese cedar plantation of Nantou Forestry Districts and to assess the influences of various degree of logging (0%, 25%, and 50% treatments) on vertebrate diversity. The results of first year study has been set 12 experimental 1 haplots and total of 6 species amphibians, 5 species reptiles were found. Higher bird species diversity of natural forest site was found than of the plantation site. However, the similar species number was found at all 12 experimental plots of the Japanese cedar areas (range 9-15, average 11.42). Shrews (Insectivora, Soricidae) were the dominant mammals in the understratum of the Japanese cedar plantation.
