Great Lakes coastal marshes support a large number of aquatic and semi-aquatic species that use them for breeding, feeding and overwintering. In eastern Georgian Bay, Lake Huron, where many coastal marshes are still relatively free from human disturbance, the integrity of coastal wetlands has been threatened by an unprecedented period of sustained low water levels for over a decade. Recently, developmental pressure on these coastal wetlands has also increased because of rising demand for water-front property for seasonal and year-round residences. It is clear that development pressure is too strong to prevent alteration of at least some wetlands on public and private lands. A more effective conservation strategy is to identify and protect essential core habitat and connecting corridors, leaving non-essential wetland habitat available for compatible development. Such a system of habitat ranking is more likely to be embraced by politicians and business interests.

大湖沿海沼泽支持大量的水生和半养育物种，它们用于繁殖，喂食和越冬。在休伦湖的乔治亚湖东部，许多沿海沼泽仍然没有人类干扰，沿海湿地的完整性受到了十年来持续持续较低的水位前所未有的威胁。最近，由于对季节性和全年住宅对水陆物业的需求不断增加，对这些沿海湿地的发展压力也增加了。显然，发展压力太大，无法防止在公共和私人土地上至少改变一些湿地。一种更有效的保护策略是识别和保护基本的核心栖息地和连接走廊，使非必需的湿地栖息地可用于兼容开发。这样的栖息地排名系统更有可能被政客和商业利益所接受。
