Peatland mapping is incomplete in remote boreal and arctic regions, and existing global wetland inventories do not isolate the area or biomass specifically dominated by Sphagnum from other peat-forming vegetation.
What would resolve this Satellite-based global peatland mapping cross-referenced with species-level vegetation surveys distinguishing Sphagnum-dominated bogs from other peatland types.
