Summary effects for TP in wetland subgroups based on a climate zone, b water type, c wetland history, and d hydrologic regime. Error bars show the 95 % confidence interval (where number of wetlands (n) is one it is based on the within study variance only). *Restored wetlands on formerly drained cropland are not included (five precipitation-driven and one wetland with continuous flow and variable HLR)
