北大武山植物資源

北大武山是台灣緯度最低的百岳,但高度達3,000公尺以上,因此氣候介於亞熱帶至涼溫帶之間,差異性大,孕育了多樣性高的植物資源。依喬木、灌木及地被分述如下:

  • 樹冠層的中、大喬木,由中海拔的闊葉樹,逐漸成為針闊葉樹混合林,最後到達高海拔的針葉樹,其中以森氏櫟、昆欄樹、紅檜、鐵杉為指標樹種,尤其以2,500公尺以上的鐵杉純林最具有代表性。
  • 小喬木與灌木以台灣杜鵑、紅毛杜鵑、玉山杜鵑、西施花、高山鴨腳木、台灣馬醉木、玉山箭竹等最為優勢,尤其每年杜鵑盛開時,將北大武山妝點得非常熱鬧,是不容錯過的景致。
  • 北大武山的地被植物相當多樣且具有特色,一年四季在步道旁爭奇鬥豔著。其中的蘭花極富觀賞價值,如台灣一葉蘭、阿里山根節蘭;蕨類植物也相當豐富,如石葦、台灣山蘇、裡白、台灣瘤足蕨等。此外,台灣百合、台灣蜘蛛抱蛋、水晶蘭、巨葉花遠志、秋海棠類等,也相當具有代表性。

North Dawu Moutain has the lowest latitude among Taiwan’s hundred mountain ranges. At an elevation above 3,000 meters, the mountain has a climate ranging from subtropical to cool-temperate. This has resulted in a rich and diverse flora.

  • Mid-altitude broadleaved forests ascend to coniferous broadleaved mixed forest and coniferous forest at the top. The signature forest is Taiwan hemlock pure forest at 2,500 meters and above. Other important speices include Mori Oak, Taiwan red cedar and Taiwan hemlock.
  • Dominant small trees and shrubs include Formosa nrhododendron , Red-hairy azalea, Yushan rhododendron, Taiwan azalea, Taiwan schefflera, Taiwan pieris and Yushania niitakayamensis.
  • North Dawu Mountain is home to many unique ground cover plants, such as Taiwan pleione and ferns like tongue fern, Formosa spleenwort, Hicriopteris glauca and Plagiogyria, as well as Aspidistra and Begonia are commonly seen.
