Lake Michigan basin, USA: piping plover habitat

Other areas of natural resource significance may be documented, depending on the type and extent of resources in the mapped area. These additional areas are not publicly managed nor do they have any special designation, but they have been identified as special places meriting spill protection. These resource areas are mapped because they are valued for natural qualities, such as habitats supporting large numbers of non-listed species. Examples include migratory waterfowl resting areas, important fishery areas, and natural communities. These areas are uniquely vulnerable to oil spills. Therefore, this coverage helps to bring such areas of the Lake Michigan Basin to the attention of spill planners and responders. The specific marina locations were obtained and quality assured/quality controlled using maps and individual feedback from various public agencies and private sector groups regarding specific sites.
