管理資訊 化學方法：Entrix(2003)報告說：滅草煙和草甘膦可殺死甘藻(Zostera japonica)和Z. marina。如果在低潮乾燥時施用除草劑，可殺死這些植物，而滅草煙的毒性更大。如果在淹水的情況下使用，則沒有效果。在處理後12個月內，所有受影響的苦草床都會康復。 物理方法：2003年4月在洪堡灣(美國加利福尼亞州)加州大學推廣工作人員和志願者開始清除甘藻(Zostera japonica)。他們試圖安裝塑膠片製造超過遮蔭殺死甘藻(Zostera japonica)，卻發現海灣的強勁浪潮會把塑膠片打到遠方(拉什頓, 2005)。作者報告說：挖除甘藻(Zostera japonica)可使本土苦草植被Z. marina迅速恢復。              管理資源 /鏈接 1.
