Analyses of historic maps and charts is aiding in the restoration of the Florida Everglades. Resource managers from a variety of agencies are using information the EHAP project has developed. Understanding where, and what type, of habitat changes have occurred is important to the restoration process. This information can be used to help set restoration targets and goals, and to determine if certain goals are feasible. As an example, restoring the marshes on Cape Sable, which have converted to open water or mangrove forests, is most likely impractical. However, preventing further loss of marsh may be an attainable goal. Additionally, change analyses aid in the development and testing of hypothesis which will further aid Everglades restoration efforts.
