Vegetation survey of southwest Florida for use in assessment of the Picayune Strand Restoration Project effects This release consists of vegetation data collected across an environmental gradient at Ten Thousand Islands National Wildlife Refuge (TTI NWR) near Naples, Florida, USA. The refuge is within the impact area of the Picayune Strand Restoration Project (PSRP), a large-scale hydrologic restoration project in southwest Florida that was authorized by the U.S. Congress in 2007. Vegetation transects were located in the following wetland types on the refuge: brackish marsh, salt marsh, and transition marsh. Data from vegetation transects established in nearby areas outside of the PSRP impact area, in Fakahatchee Strand Preserve State Park (FSPSP) and Big Cypress National Preserve (BICY), are also included. The study spanned... Categories: Data; Tags: Big Cypress National Preserve, Botany, Brackish Marsh, Copeland, Ecology, All tags...

These rasters represent projections of future habitat type, change in surface elevation above Mean Sea Level, and total sediment carbon accumulation since 2011 in coastal wetland habitats. Projections were generated in 20-year increments for 100 years for five amounts of sea-level rise, three amounts of suspended sediment concentrations, and two alternative configurations of the U.S. Interstate-5 causeway as it crosses the Nisqually River to either prevent or allow inland habitat migration (a total of 30 scenarios). The full methods and results are described in detail... Tags: Brackish Marsh, Emergent Tidal Wetland, Estuarine Coastal, Freshwater Tidal Marsh, High Salt Marsh, All tags...

Vegetation cover was estimated in permanent plots, and soil cores were collected for determination of bulk density, organic matter content and texture. VLMw was measured using rod surface elevation tables, while accretion was measured using feldspar marker horizons (i.e., RSET-MH technique).

Data were collected from a brackish marsh at Pointe-aux-Chenes State Wildlife Management Area and a tidally influenced freshwater marsh at Salvador State Wildlife Management Area. Both sites were located within the coastal zone of Louisiana, USA.
