Redox potential, indicative of the active pathways of organic matter decomposition, was monitored for 2 years in a boreal peatland with three drainage regimes. Contrary to expectations, the water table level and redox potential were not found to be correlated in a monotonic fashion; thus, the relationship between the water table level and redox conditions is not modellable using non-dynamic models.
