National Indicators reflect the range of estimated probabilities (expressed as a frequency of occurrence) of a species occurring in wetlands versus non-wetland across the entire distribution of the species. A frequency, for example, of 67%-99% (Facultative Wetland) means that 67%-99% of sample plots containing the species randomly selected across the range of the species would be wetland. When two indicators are given, they reflect the range from the lowest to the highest frequency of occurrence in wetlands across the regions in which the species is found. A positive (+) or negative (-) sign was used with the Facultative Indicator categories to more specifically define the regional frequency of occurrence in wetlands. The positive sign indicates a frequency toward the higher end of the category (more frequently found in wetlands), and a negative sign indicates a frequency toward the lower end of the category (less frequently found in wetlands). A question mark (?) following a National ...
An erosion forum is a gathering of experts, stakeholders, and the public to discuss issues related to the societal and economic aspects of erosion, including its causes, impacts, and potential solutions. These forums can focus on various types of erosion, such as coastal erosion, soil erosion, or erosion caused by rivers. They serve as a platform for sharing knowledge, best practices, and fostering collaboration to address the challenges of erosion.
