Lodgepole pine in Iceland: biomass gains cannot be interpreted without ecological costs. Response to Riege et al. - New Forests We respond to Riege et al. (New For 56:68, 2025), who present valuable new data on early biomass accumulation by lodgepole pine (Pinus contorta) in Iceland. We argue that this finding cannot be evalua...
