预计气候变化将增加许多沿海植物群落的压力。沿着北美海岸的大部分地区，人类活动对环境造成的生境退化已经威胁到潮汐沼泽和水下水草床的群落结构。这些社区历史上提供的生态服务的潜在损失一直是积极控制入侵植物，如芦苇和黑藻的长期理由。越来越多的证据表明，入侵物种，如芦苇和H。verticillata的研究表明，面对日益增加的压力，对这些物种对沿海生态系统的影响采取更务实的做法可能是明智的。这些物种的显着的弹性，以控制的努力和他们的竞争力的成功和比较活力，强调系统和能力，以提供至少一些有益的服务联合收割机，建议一些入侵物种可能有一个有用的作用，在管理沿海生态系统。
Climate change is projected to increase stress for many coastal plant communities. Along large portions of the North American coast, habitat degradation from anthropogenic changes to the environment already threaten the community structure of tidal marshes and submerged aquatic grass beds. The potential loss of ecological services historically provided by these communities has been a long-standing rationale for aggressive control of invading plants such as Phragmites australis and Hydrilla verticillata. Increasing evidence of ecological services provided by invasive species such as P. australis and H. verticillata suggest that, in the face of increasing stress, it may be prudent to take a more pragmatic approach regarding the effect of these species on coastal ecosystems. The notable resilience of these species to control efforts and their competitive success and comparative vigor in stressed systems and capacity to provide at least some beneficial services combine to suggest some invasive species may have a useful role in managed coastal ecosystems.
