經現地植物調查結果,火燒後之植物生長及入侵,一般混交林區比木麻黃純林區快速,且植物種類較豐富。樣區火燒後能夠萌蘗之木本植物包括:苦楝(Melia azedarach L.)、構樹(Broussonetia papyrifera(L.)L’ Herit. ex Vent)、銀合歡(Leucacna glauca (L.)Benth)、黃槿(Hibiscus tiliaceus L.)、蓮葉桐(Hernandia Sonora L.)、馬纓丹(Lantana camara L)、木麻黃(Casuarina equisetifolia L.)、山黃麻(Trema orientalis Blume)、雀榕(Ficus superba Miq. Var.japonica Miq.)等;建議這些樹種可配合相關之防火性植物,共同栽植配置於海岸防火綠帶之中。較耐燃之防火性植物可供林火防災之用,萌蘗型植物則具有火燒復育之功用。

The primary vegetation growth on costal windbreak burned land was investigated in order to find the pioneer species and the best species for growing fire-break trees at the coastal windbreak area.
Results indicated that, plants growth and invasion are faster on mixed forest burned land than in monoculture Casuarina forest burned land. Plant species are more abundant on mixed forest burned land. The woody plants which can sprout quickly after burning are Melia azedarach L., Broussonetia papyrifera (L.) L' Herit. ex Vent, Lantana camara L., Casuarina equisetiflolia L., Trema orientalis Blume., and Ficus superba Miq. Var.japonica Miq..
Soil pH, electrical conductivity and saturated hydraulic conductivity were changed after burning. Electrical conductivity of burned Casuarina forest soil is about 1868 µs/cm, and the saturated hydraulic conductivity is down to 0.014 mm/sec. High base concentration and low infiltration rate are unfavorable for plant growth. In order to build a suitable plant growth environment, soil should be amended on forest burned land especial for Casuarina.
