The dataset includes Land Use/Land Cover types throughout the Chenier Eco-Region in Southwest Louisiana. Using the 2015 National Aerial Imagery Program (NAIP) dataset (1m) as the basemap, E-Cognition image objects were derived from the multiresolution segmentation algorithm at 75 and 250 segments. Attempts to refine the data training methods using E-cognition, to extrapolate automating categories of this information to the entire map resulted with exceedingly low accuracy. Therefore, a raster was produced by piecing together several data resources, which provide reliable data for specific LandUse/LandCover (LULC) categories. This process involved stitching together more reliable sources for specific categories to...

The coastal prairie of Louisiana is classified as a Tier 1 Habitat in the Louisiana Department of Wildlife and Fisheries’ Wildlife Action Plan, meaning that it is a priority habitat of primary conservation concern. Declines in pollinator populations worldwide have prompted questions about the role of such grasslands as habitat for pollinators. In this study, we surveyed bee populations and the plant communities present in the following three grassland types in southwest Louisiana: prairie remnants, restored prairies, and old fields.

This release consists of soil surface elevation, also called vertical land motion of the wetland (VLMw), and vertical accretion data collected over time across an environmental gradient at Ten Thousand Islands National Wildlife Refuge near Naples, Florida, USA. VLMw was measured using rod surface elevation tables, while accretion was measured using feldspar marker horizons (i.e., RSET-MH technique). Stations were located in the following wetland types: brackish marsh, salt marsh, transition marsh, and mangrove forest. Vegetation cover in the vicinity of the RSET-MH stations was described. The study spanned six years, from 2011 to 2017.
