Element Definition
Wetlands are defined as areas identified as wetlands in authoritative federal or state wetland inventories based on hydrology, vegetation, and soil characteristics. For this element, wetlands include only features classified as wetlands in the source datasets at the time of data compilation. Areas not mapped or classified as wetlands in these inventories are not included.
Mapped Feature Description
This element is displayed as polygon features representing the mapped extents of wetlands in Illinois. The polygons reflect wetland boundaries as delineated in the source datasets at the time of publication. The map does not depict wetland functional assessments, regulatory buffers, mitigation status, water quality conditions, seasonal variability, or jurisdictional determinations beyond the mapped wetland boundary.
