一般影響
此多年生的叢生禾草有時會形成連續的覆蓋，在鬆軟濕地、開放的濕性和乾燥的棲息地。它釋放非常持久的植物相剋物質(水稻1972，在史密斯)。死亡的木料提供林火良好的燃料。它會受林火刺激，每次火燒後會大幅增加其覆蓋(史密斯，帕曼和瓦姆普勒, 1980，在史密斯)。它所在之處，林火強度和面積都會增加(史密斯)。美國俄克拉荷馬州的調查顯示，春季一次的火燒無明顯改變，兩次的火燒會使它增生，而夏季或秋季土壤乾燥時燃燒後會使它大幅減少。鬚芒草(Andropogon virginicus)會侵入森林和其他原生植被，沿軌道(ESC)。林相單一的純林則能經由競爭和植物相剋作用，堅持下來。(Uchytil, 1992)。
地點特有的影響：Hawaii (Hawai‘i) Is. (United States (USA)) 
改變林火機制: Dried material contributes to fire hazard, and reproduction is encouraged by fire. Kaua`i Is. (United States (USA))
改變林火機制: Dried material contributes to fire hazard, and reproduction is encouraged by fire. Kaua`i Is. (United States (USA))
其他: It is dormant during the rainy season, which Mueller-Dombois (1973) has shown leads to increased erosion in some areas.
改變林火機制: The dead material provides an excellent fuel for fires. It is fire-stimulated; its cover increases dramatically with each fire (Smith, Parman, and Wampler 1980). In areas where it occurs, both fire intensities and acreage burnt have increased. Lana`i (Lanai) Is. (United States (USA))
改變林火機制: Dried material contributes to fire hazard, and reproduction is encouraged by fire. Moloka`i (Molokai) Is. (United States (USA))
改變林火機制: Dried material contributes to fire hazard, and reproduction is encouraged by fire. West Maui (United States (USA))
