Data from: Overcoming establishment thresholds for peat mosses in human-made bog pools.Ecological Applications.In this study, we theoretically explore if a floating peat mat and an open human-made bog lake can be considered two alternative stable states using a simple model, and experimentally test in the field whether stable states are present, and whether a state shift can be accomplished using floating biodegradable structures that mimic buoyant peat. We transplanted two peat moss species into these structures (pioneer sp. Sphagnum cuspidatum and later-successional sp. S. palustre) with and without additional organic substrate.This dataset contains data of plant performance of the experimental plots and of surface water quality.
