Biomass and primary productivity of an Alnus viridis stand – a case study from the Schächental valley, Switzerland
Green alder (Alnus viridis) stands are spreading rapidly in the subalpine belt of the Swiss Alps. To understand this rapid colonisation, estimates of above ground biomass and net primary productivity were made in an old-growth pure stand of Alnus viridis in central Switzerland. A total above-ground...
