北大武山林相變化

北大武山步道海拔高度介於1,540- 3,092公尺間,年均溫14°C由於地形變化及氣候差異性大,形成了多樣性豐富的森林環境。

  • 1,540-1,800公尺間是暖溫帶闊葉林,以樟科及殼斗科為優勢樹種,且有豐富的藤本及附生植物。
  • 1,800-2,500公尺間是暖溫帶針闊葉混合林,長年雲霧繚繞,針葉樹、闊葉樹、灌木及地被植物完整,以昆欄樹及紅檜為優勢樹種。
  • 2,500公尺以上地區為涼溫帶針葉林,以台灣鐵杉為優勢種,林下則以箭竹為主。
 
Between 1,540 meters and 3,092 meters, North Dawu Mountain has sharp variations in topography and climate, creating diverse forest ecology.
  • Between 1,540 and 1,800 meters is warm-temperate broadleaved forest, with many species of Lauraceae and Fagaceae families.
  • Between 1,800 and 2,500 meters is warm-temperate coniferous and broadleaved mixed forest.
  • Above 2,500 meters is cool-temperate coniferous forest, where Taiwan hemlock is the dominant species.
