Overview & Objective(s): A foundation for the Everglade's restoration must include a clear understanding of the pre-drainage south Florida landscape. Knowledge of the spatial organization and structure of pre-drainage landscape communities such as mangrove forests, marshes, sloughs, wet prairies, and pinelands, is essential to provide potential endpoints, restoration goals and performance measures to gauge restoration success. Information contained in historical aerial photographs of the Everglades can aid in this endeavor. The earliest known aerial photographs, from the mid to late 1920s, and resulted in the production of T-Sheets (Topographic Sheets) for the coasts and shorelines of south Florida. The T-Sheets are remarkably detailed, delineating features such as, shorelines, ponds, and waterways, in addition to the position of the boundary between differing vegetation communities. If followed through time changes in the position of these ecotones could potentially be used to judge effects of changes in the landscape of the Everglades ecosystem, providing a standard by which restoration success can be ascertained. The value of translating Everglades aerial photography into digital format and the development of a standardized online accessible database of geospatial imagery is great. Investigators from all four USGS Divisions, the National Park Service, the South Florida Water Management District and the Florida Coastal Everglades LTER program have all expressed interest in such a collection when the initial concept was proposed.

Status: This project operates on funds as they become available.

Specific Relevance to Information Needs Identified in DOI's Science Plan in Support of Ecosystem Restoration, Preservation, and Protection in South Florida (DOI's Everglades Science Plan) [See Plan on SOFIA's Web site: http://sofia.usgs.gov/publications/reports/doi-science-plan/]:

The various data layers produced by this project will be used by CERP teams in every region of the greater Everglades. As the different photosets get scanned they will be turned into GIS layers that can be used as tools by the CERP teams as individual projects get planned and implemented. The SFWMD expressed interest in using our products to help define performance measures for the ridge and slough province of the Everglades and for mapping the “white zone” in the area of the C-111 spreader canal. These are but two examples of how products from this project will aid and assist CERP.

Key Findings:

  1. CERP is using a vegetation map from 1940 as the “base-line” for restoration. Our results indicate that vegetation communities in the coastal Everglades underwent major changes between 1927 and 1940. So the “base-line” is not necessarily correct.
  2. Not all changes in vegetation are related to altered hydrology, some appear more closely tied to sea level rise or catastrophic, large-scale disturbance from hurricanes.
