花蓮縣平地造林區森林性動物監測計畫

簡介

棲地復育與重新植林被認為可改善或重建因林木砍伐或農牧業經營而被移除的天然植被，減緩棲地劣化、生物多樣性喪失、與氣候變遷等問題。花蓮縣大農與大富農場的平地造林計畫使於2002年起，將原本的蔗田改植本土原生樹種，期在平地建立森林景觀。在台灣哪些物種棲息於平地森林，復林過程中動物群聚組成如何變遷，有待需長期觀測。為提供植林初期物種組成資料，作為監測基礎，本計劃調查大農與大富地植林地目前地棲性昆蟲、兩棲爬蟲類、鳥類與哺乳動物的種類、相對量與其季節變化，並與周邊海岸山脈動物相比對，以檢視與評估植林地作為森林性物種棲地的現階段成效與未來目標。調查結果於大農與大富共記錄到地棲昆蟲12目、兩棲類13種、爬蟲類9種、鳥類48種、與哺乳動物6種，物種。大農與大富動物群聚的差異不大，各樣區的物種組成與環境因子及棲地狀況相關。對照海岸山脈的物種組成，大農與大富雖有部分樹上活動的鳥種，但森林性動物的種類與數量仍有限。未來可以記錄森林發展過程中動物群落組成的變遷、評估棲地維護與管理成效為目的，結合在地資源，選取適當動物種類或類群，進行監測，作為園區管理的依據與支援。 Forest regeneration can restore degraded habitat and conserve biodiversity, and is widely practiced in human modified landscapes to enhance conservation value of man-made habitats. Danung-Dafu afforestation area project aims to regenerate a large track of forest in the flat land of eastern Taiwan where most low-land primary forests have gone. What the candidate forest dwelling organisms would be and how they colonize and establish populations in this area awaits to be learned. We surveyed terrestrial insects vertebratds in Danung-Dafu area and nearby area of the Coastal Mountain Range to provide “quasi-baseline” information on fauna in the early phase of afforestation for long-term monitoring, and to evaluate the current virtue of the area as habitats for forest animals. Species compositions are similar in Danung and Dafu areas, which relate to environmental and habitat conditions. Referenced to the species composition in the Coastal Mountain Range, fauna in Danung-Dafu area is dominated by species of open fields and grasslands. There are limited forest species at present, although some canopy bird species occurred. Objectives and pontential target species for long-term monitoring are suggested.
