海南長臂猿全球數量只剩30隻,聚居在海南森林裡,屬全球頻危動物十大之一。616Please respect copyright.PENANAw24X77TBUe616Please respect copyright.PENANAhBUgTHuOl2

牠們擁有獨特的習性,近乎不會在陸地行走,只會在繁盛的樹冠中跳躍走動。616Please respect copyright.PENANA8lIhknvw8Y

(圖2)然而,在颱風天災及人為活動的影響下,榭木數量逐漸減少,導致牠們的悽息地面積越來越細,越漸孤立。616Please respect copyright.PENANAVBHTdihJUn616Please respect copyright.PENANAY2SLhlmE1c

(圖3)其中有科學家發現(Ref1),一場颱風過後摧毀了不少樹木,使長臂猿慣常的路徑有所變動。616Please respect copyright.PENANAv0ym5vHyet616Please respect copyright.PENANAY6ZvbDkGQM

本應無縫連接著樹冠的地方出現相隔約10米的缺口,有不少臂猿均挽有猶豫態度應否飛躍對面,而飛躍過程中亦甚為驚險。616Please respect copyright.PENANAOM9POQoTQp

(圖4)科學家最後找來爬樹高手,共花上5000美元建造兩條吊橋連接樹冠。616Please respect copyright.PENANA1iSKuJqSKM616Please respect copyright.PENANATFfWqU98XD
616Please respect copyright.PENANADIuRrX1n20
吊橋建成176日後,才有第一隻長臂猿嘗試試用,隨後亦招來不少年輕臂猿用上各種方式行走。616Please respect copyright.PENANA6mBq0k4cPb
但根據他們的觀察,年長的長臂猿依舊照用跳樹的方式走動,觀察小組只有錄得年長的長臂猿一次的吊橋使用。616Please respect copyright.PENANABQ5fuiqoUI

吊橋的建立,明顯只是短期的解決辦法。616Please respect copyright.PENANA1M5I4AWl0B
如何有效保育頻危物種及預防物種頻危化,是一道所有人也應該深思的問題。616Please respect copyright.PENANAFqk2Pal6Ks
