太麻里研究中心台灣水鹿族群監測

本研究至2016年12月為止，於林業試驗所太麻里研究中心1998年所建造的原生闊葉樹種混合林內，以自動監測相機對台灣水鹿之族群動態進行為期39個月，前後12次監測時間不等的連續監測。經辨識後篩選出410筆有效照片紀錄，並換算為出現指數OI，以分析鹿群分布的區域性差異，以及族群數量的波動情形，用以評估闊葉樹混合林之建造，在野生動物復育上的生態效益。分析結果發現：本造林地內的台灣水鹿，以雄鹿的出現次數較多，約為雌鹿的2.7倍。鹿群的OI值在各監測點間及各監測季間，均呈極顯著差異(p<0.001)，顯示鹿群在本造林地分布不均勻，且數量呈現季節性的波動。整體而言，鹿群出現於本造林地的數目，呈現穩定增加的趨勢。
本資料集內容與資料為林業試驗所105年「闊葉樹混合林之生態效益監測(4/5)」結案科技計畫所執行之成果。

This study progressed in a hardwood mixed stand establishedin 1998 at Taimalii Research Center, TFRI. Camera traps were used to monitorthe population dynamics of Formosan Sambar (Rusa unicolor Swinhoii) duringJuly, 2012 to September, 2015. After 12 continuing monitoring season of 39 months,410 effective picture records were identified and compose to OI to analyze thedistribution and seasonal fluctuation of sambar’s population at different monitoringpoints. According to the results, the effective records of male sambar was muchhigher than female’s with a occurrence ratio of (♀:♂=1:2.7).Extreme significant variation occurred between both monitoring points andseasons on the OI of sambar’s population, showed that the distribution of sambar’spopulation was uneven in the stand and inclined to grouped at some “hot spot”.Meanwhile, the relative abundance of sambar’s population were fluctuating andgrowing stably during the monitoring period.
