生態 分佈 管理 影響 參考資料 聯繫


         一般影響

    聚藻(Myriophyllum spicatum)長成茂密侵襲,遮蔭、取代了其他水生植物,它比被取代的原生植物,食品資源價值較小。高密度時會減少水生昆蟲,使魚類的食物資源減少。大型食肉魚類失去覓食空間,而且獲得獵物的效率也會降低。另一個影響是大毯狀植被腐爛後會減少水中氧含量。茂密的毯狀植被,干擾阻礙水分運輸移動與休閒活動,如游泳,划船,釣魚和滑水。

    滋擾人類: Interferes with recreational activities such as swimming, boating, fishing and water skiing.

    競爭: Shades out native aquatic plants that have higher value for fish and bird species

    雜交: Hybridisation with native milfoils threatens to jeopardise biocontrol of the weed species and facilitate further displacement of native species
