Picayune Strand Restoration Project Background, Issues and Needs 279 miles of roads and 48 miles of canals constructed on 55,000 acres by private developer in late ’60s Resulted in over-drainage of northern and southern Golden Gate Estates Caused extreme flows to estuaries, affecting salinity and marine habitat Resulted in drier conditions inland Expansion of invasive plant species such as Cabbage Palm and Brazilian Pepper Loss of Cypress forests Plant species changed, quality of animal habitat declined

Missing Piece of the Puzzle Collier Seminole State Park Everglades National Park Big Cypress National Preserve Urban Development Southern Golden Gate Estates Rookery Bay National Estuarine Research Preserve Fakahatchee Strand State Preserve Picayune Strand State Forrest Florida Panther National Wildlife Refuge 10,000 Islands National Wildlife Refuge Restores ecological connectivity between publicly owned lands

Summary of Benefits Restores freshwater flows to estuaries Restores upland/wetland habitat in watershed Restores pre-drainage watershed flow pattern to a sheet flow condition Increases groundwater levels Restores habitat for endangered/threatened species (Florida panther, woodstork, etc.) Provides for better fire management
