The Site, which occupies a major section of the Eastern Lake Michigan shoreline of northern Door County, comprises diverse examples of regionally and globally significant wetland communities, including interdunal wetlands and northern wet-mesic forest. It supports numerous species of fauna and flora including the rare dwarf lake iris (Iris lacustris) and over 150 species of birds that use the site for nesting or as staging areas during autumn and spring migrations. It also hosts the largest known population of the federally-endangered Hine’s emerald dragonfly (Somatochlora hineana). The Site is part of a karst hydrologic system that contributes to accelerated groundwater recharge. Areas of groundwater recharge are a critical habitat component for the Hine’s emerald dragonfly. Threats to the Site include invasive species such as giant red grass (Phragmites australis), urban development, and increasing recreational vehicle use. Climate change has also been identified as a potential threat, as it could lead to changes in levels of the groundwater and of Lake Michigan, changes in water pH and declines in species richness and diversity.
