摘要

Five freshwater ponds (Long, Round, Snow, Ryder and Great) within Cape Cod National Seashore, Massachusetts, USA, that had been invaded by Phragmites australis were randomly selected for treatment. On 3 April 2003, all P. australis stems in each population were manually broken underwater and removed from the ponds. Removal treatments were repeated on 9 June and 1 September 2003. Long and Round Ponds showed the least amount of decline (<70%) while populations in Snow, Great and Ryder Pond decreased by >90%. Repeated underwater breakage and removal of stems significantly reduced P. australis population size the following year. No stems reemerged in 12 out of 15 permanent plots while reductions in total stand size ranged between 59 and 99%..
