Fig. 4: Overall IFI values for across different stream orders and ecoregions.
From: Degradation of floodplain integrity within the contiguous United States
a Analysis of IFI by maximum stream order. b Analysis of IFI by aggregated Level III Ecoregions. (Key: NPL Northern Plains, XER Xeric, WMT Western Mountains, UMW Upper Midwest, SPL Southern Plains, NAP Northern Appalachians, SAP Southern Appalachians, TPL Temperate Plains, CPL Coastal Plain). The bottom of the boxes represents the 25th percentile and the top of the boxes represents the 75th percentile. The line through the box represents the median value, and the diamond points represent the mean value. Error bars above and below the boxes represent the 90th and 10th percentiles, respectively, and black dots represent data outliers.
