中文摘要 | 墾丁國家公園富含低海拔森林,且遊憩人數眾多,要對該地野生動物棲地與族群進行經營管理,需先瞭解動物之族群量、空間分布與人為影響。本研究利用現有路徑作為調查樣線,步行進行沿線調查,紀錄猴群之位置、組成、與觀察者間距離及所在棲地類型,以瞭解現有台灣獼猴族群密度與空間分布。2009年進行全區調查,樣線總長度為76.8公里,相對猴群密度為0.39群/km(95%CI: 0.19-0.59群/km),森林性棲地的估計猴群密度為2.90群/ km2(95%CI: 1.40-4.41群/km2),現有猴群數估計為243群(95%CI: 100-386群)。2010年於國家公園境內天然林與農耕地鑲嵌之滿州鄉區域之調查顯示,猴群趨向均勻分布。國家公園西半部大面積開發處已無獼猴分布,東半部之聚落亦影響獼猴分布,猴群多在森林性棲地活動,但鑲嵌於森林棲地之農地並未影響獼猴密度。墾丁國家公園具有豐富獼猴資源,著重於保育現有森林覆蓋面積及林相完整可維持台灣獼猴資源量。 |
英文摘要 | The Taiwanese macaque in Kenting National Park were studied in or-der to investigate the species’ current population size and spatial distribution in the re-gion. Sightings of macaque troops were recorded through line sampling on chosen ex-isting roads, trails and paths in the national park. Data on the observer’s distance to the troops, location of and habitat type used by the troops were collected. A total of 76.8 km of trails in length were sampled three times between April and November 2009. The survey found an encounter rate of 0.39 macaque troop per kilometer (95%CI: 0.19-0.59). The density of macaques was estimated to be 2.90 troops/km2 (95%CI: 1.40-4.41) in the forested habitat, and the estimated population size was 243 individuals (95%CI: 100-386). Sampling lines with different levels of agricultural development were found to have similar estimated density of macaque troops in the Manzhou area. The distribu-tion of macaques was limited to the eastern part of the park where forested habitat type was used by the macaques most frequently. Macaque troops were not attracted to human settlements nor to the crops in the surroundings of the settlements. Most macaque troops were observed over 600m away from the settlements along the sampling line stretching out of the settlements. High density of macaques was found in the forested areas of the park. From this study, preservation of forest lands and plant community is recommended to sustain the precious resource of Taiwanese macaques in the national park. |
