健康的海草被认为是河口生态系统功能的主要指标。在北美太平洋沿岸，至少存在两种大叶藻的同源物：本土大叶藻和引进的大叶藻。粳稻被一些人认为是“入侵性”的，因此对生态和经济有害，而另一些人则认为它是良性的或可能是有益的。粳稻未出现在联邦或俄勒冈州的入侵物种或有毒杂草名单上。然而，加利福尼亚州将其列为入侵性和有毒杂草；华盛顿州最近将其列为有毒杂草。我们描述了北美对这些同类物种的管理动态，并强调了这些决策背后的科学和政策。近年来，国家层面的管理策略涵盖了Z的历史保护。粳稻是华盛顿州消灭加利福尼亚州的优先栖息地。加拿大俄勒冈州和不列颠哥伦比亚省似乎没有关于 Z 的具体政策。粳稻。这种分散的管理方法与美国其他地区和世界各地保护海草的努力相矛盾。科学必须在 Z 的评估中发挥关键作用。粳稻生态学以及管理措施的近期和长期影响。这里提供的信息和建议可以作为提供科学数据的基础，以便制定更明智的管理决策并帮助制定统一的管理策略。粳稻。
Healthy seagrass is considered a prime indicator of estuarine ecosystem function. On the Pacific coast of North America, at least two congeners ofZosteraoccur: nativeZostera marina, and introduced,Zostera japonica.Z. japonicais considered “invasive” and therefore, ecologically and economically harmful by some, while others consider it benign or perhaps beneficial.Z. japonicadoes not appear on the Federal or the Oregon invasive species or noxious weed lists. However, the State of California lists it as both an invasive and noxious weed; Washington State recently listed it as a noxious weed. We describe the management dynamics in North America with respect to these congener species and highlight the science and policies behind these decisions. In recent years, management strategies at the state level have ranged from historical protection ofZ. japonicaas a priority habitat in Washington to eradication in California. Oregon and British Columbia, Canada appear to have no specific policies with regard toZ. japonica. This fractured management approach contradicts efforts to conserve and protect seagrass in other regions of the US and around the world. Science must play a critical role in the assessment ofZ. japonicaecology and the immediate and long-term effects of management actions. The information and recommendations provided here can serve as a basis for providing scientific data in order to develop better informed management decisions and aid in defining a uniform management strategy forZ. japonica.
