Peatland plants began recovering long before reference communities returned

Minnesota rewetted bogs gained characteristic vegetation after moss transfer, but reference similarity remained low.

Evidence: Peer-reviewed
Geography: Two drained peatland restoration sites, northern Minnesota, USA
System: Acidic peatland hydrology, moss transfer and community recovery

WHAT THE EVIDENCE SAYS

At two peatland sites, rewetting and moss transfer shifted vegetation toward wetland species over five years. Similarity to 43 reference wetlands rose from under 5% to just 9–15%; floristic conservatism increased and invasive cover fluctuated.

WHY IT MATTERS / OUR READ

Management read: separately track water table, moss-layer survival, community composition, non-native plants and carbon-related indicators over repeated years; rising water alone is not restored peat formation.

CAVEATS / UNCERTAINTY

Two unrandomized treatment sites cannot isolate intervention effects. Vegetation similarity does not directly measure peat accumulation or full hydrologic recovery.
