The dataset includes Land Use/Land Cover types throughout the Chenier Eco-Region in Southwest Louisiana. Using the 2015 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 LULC categories. This process involved stitching together more reliable sources for specific categories to apply to higher resolution (75) segmentation product....

Managers typically estimate wildlife abundance using surveys within a timeframe that favors increased detectability; however, the ability to account for probabilities of inclusion, detection, and/or presence within a given sampling area is often limited. Cranes provide a good opportunity to research count accuracy because they are large, conspicuous, and often congregate during part of the year, typically on staging areas (i.e., fall and spring) or on wintering grounds. The objectives of this paper are twofold: (1) to evaluate how environmental factors influence crane movement in and out of crane survey areas to identify the best window of availability for annual survey counts, and (2) to evaluate environmental...

Enduring features (EFs; geophysical settings) are worthy conservation targets. We assembled data on EFs for the nation and performed an ecoregion-based GAP Analysis on their conservation status. Ecoregions that circumscribe mountains tend to have more EFs, and ecoregions in the west, where public lands make up more of the total land area, have more EFs within conservation lands. The middle of the country is relatively low in EF diversity, but nonetheless the number of EFs in conservation lands is low. Areas of high EF diversity in the Edwards Plateau also contained a diversity of rare species occurrences. We generated a new EF data set for the eastern USA and evaluated the distribution of rare species in terms of...
