Data from: Can frequent precipitation moderate drought impact on peatmoss carbon uptake in northern peatlands?
Northern peatlands represent a large global carbon store that potentially can be destabilised by summer water table drawdown. Precipitation can moderate negative impacts of water table drawdown by rewetting peatmoss (Sphagnum spp.), the ecosystems’ key species. Yet, the frequency for such rewetting...

Northern peatlands represent a large global carbon store that potentially can be destabilised by summer water table drawdown.
