摘要

我們於2001年2-7月在臺北市立木柵動物園後山的研究樣區內共發現穿山甲洞穴32個，其中僅有2個為使用中或剛使用過之洞穴。洞穴開口處的平均直徑為21.1cm，平均深度至少為108.3cm，洞口坡面的平均坡度為33.1°。穿山甲在人為活動稀少的木柵動物園後山次生林中，對洞穴棲地的選擇並無偏好，洞口周圍植株覆蓋度與隨機點間並無顯著差異。以穿越線調查樣區內穿山甲可能採食的舉尾蟻(Crematogaster spp.)蟻窩數目，估算出1.6ha的樣區內約有106個蟻窩(66.3 nests/ha)。然而在調查過程中，並未發現有穿山甲採食舉尾蟻窩的痕跡。未來仍需進行更多的野外研究，以期對穿山甲之棲地選擇能有較深入之瞭解。

We found 32 Taiwan Pangolin's (Manis pentadactyla pentadactyla) burrows in the Taipei Zoo at Mnchia area from February to July,2001.Only two burrows showed signs for being used recently. The average diameter, depth and slope of the burrows were 21.1cm, 108.3cm and 33.1°,respectively.The pangolin did not show strong preference for habitat selection in this secondary growth forest with low human disturbance. The vegetation coverage nearby the burrows and the random points had no significant difference. We found 106 Crematogaster spp. nests, a potential food for pangolins, and estimated the density as 66.3 nests/ha with the transect line method in a 1.6 ha sampling area. However, we did not see any sign of pangolins preying upon the Crematogaster spp. More future field studies are needed in order to gain a better understanding of the pangolin habitat use.
