Response of wetland soil carbon to groundwater conservation: Probabilistic outcomes from error propagation

- Whether restored wetland hydrology improves wetland function often goes unstudied.
- I investigate if reduced groundwater pumping enhances wetland soil carbon (C) storage.
- Monte Carlo methods propagate error through 3 relationships linking pumping to soil C.
- Less pumping enhances soil C, but C gains are uncertain at severe pumping cutbacks.
- The dynamic response of soil C to soil inundation time accounts for most uncertainty.
