List Compiled by
The wetland indicator represents the estimated probability (likelihood) of a species occurring in wetlands versus non-wetlands in the region. The probability percentages applied to each indicator category were provided to enhance an understanding of this methodology. The regional indicator assignments are not based on the results of a statistical analysis of the occurrence of these species in wetlands. The indicator assignments are the best approximation of wetland affinity for these species based upon a synthesis of submitted review comments, published botanical manuals and literature, and field experience. If a Regional Panel was not able to reach a unanimous decision on a species, NA (no agreement) was recorded. An NI (no indicator) was recorded for those species for which insufficient information was available to determine an indicator status or that were not considered by the Regional Panel. An asterisk (*) following a regional indicator identifies tentative assignments based on limited information or conflicting review. 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). A negative sign indicates a frequency toward the lower end of the category (less frequently found in wetlands).
Indicator Categories
The wetland indicator categories should not be equated to degrees of wetness. Many Obligate Wetland species occur in permanently or semipermanently flooded wetlands, but a number also occur and some are restricted to wetlands that are only temporarily or seasonally flooded. The Facultative Upland species include a diverse collection of plants that range from weedy species adapted to a number of environmentally stressful or disturbed sites (including wetlands) to species in which a portion of the gene pool (an ecotype) always occur in wetlands. Both the weedy and ecotype representatives of the facultative upland category occur in a variety of wetland habitats, ranging from the driest wetlands to semipermanently flooded wetlands.
The actual frequency of occurrence of a specific species in wetlands may be anywhere within the frequency range of the indicator category. For example, some species assigned to the Facultative Upland indicator category may actually have a frequency toward the lower end of the category whereas other species may actually have a frequency toward the upper end of the category.
