         一般影響

    蔥芥(Alliaria petiolata)能形成緻密的植群,因為它沒有天敵,它在受干擾地區的茂盛地生長。在美國東部和中西部的許多森林地區,蔥芥會和原生植物競爭光線,養分,水分和土壤,淘汰掉原生植物。沒有了這些寶貴的資源,依賴於這些原生植物為食物的野生動物只能離開(PCA, 2006)。蔥芥會干擾珍稀蝶種Pieris napioleraceae和西維吉尼亞白蝴蝶產卵。雌蟲產的卵可以孵化,但幼蟲無法在蔥芥叢中完成發育(NatureServe. 2007)。



         地點特有的影響:
    United States (USA) English 
    棲地改變: In many forest areas of the eastern and midwestern USA, Alliaria petiolata outcompetes native plants for light, nutrients, moisture and soil. Wildlife species dependant on these native plants for food are left without these valuable resources (PCA, 2006). The presence of garlic mustard interferes with oviposition of the rare native butterflies Pieris napi oleraceae and West Viginia white butterfly (please see Pieris virginiensis for more details on its conservation status). The native hosts of P. napi oleraceae and P. virginiensis are toothworts Cardamine concatenata [Dentaria laciniata] and Cardamine [Dentaria] diphylla. Eggs laid by females hatch but larvae are unable to complete development on garlic mustard (NatureServe. 2007).

    生態系統變化: Garlic mustard is one of the few non-indigenous herbaceous species able to invade and dominate the understory of North American forests.
