资源简介:
<span style='color:rgb(32, 31, 30); font-family:"Segoe UI", "Segoe UI Web (West European)", "Segoe UI", -apple-system, BlinkMacSystemFont, Roboto, "Helvetica Neue", sans-serif; font-size:14.6667px;'>This layer identifies potential locations for development of habitat creation and/or improvement projects to benefit the Eastern Black Rail (Laterallus jamaicensis jamaicensis). Colored areas represent 30 km buffer around 3 levels of occupancy probability in tidal wetlands for the Eastern Black Rail ((blue: 0.2-0.25, pink: 0.25-0.5, and red: >0.5); Stevens et al. in prep) as well as inland detections of Black Rails in Florida (orange) that were not part of the occupancy analysis (Schwarzer, unpublished data). Although Black Rails have been known to disperse long distances, a buffer of 30km from potentially occupied areas was chosen to maximize Black Rail recruitment to newly created habitat. Incompatible land cover types within these buffers (Developed open space [low intensity, medium intensity, high intensity], unclassified, open water, forest [deciduous, evergreen, mixed], woody wetlands; National Land Cover Dataset 2019) were removed so that only land with potential for Black Rail habitat management is shown. This buffering tool is still in development, with a projected completion date of mid-2022.</span>
