Biomass of Picea abies and Fagus sylvatica in highland and lowland stands dataset

Aboveground biomass in chronosequences of 24 <i>F. sylvatica </i>and 24 <i>P. abies </i>stands in Poland (7-117 years old), located both in lowlands and highlands (12 stands of each species per group). We cut and weighted 192 sample trees, and we measured carbon content in wood, bark, branches and leaves. We also developed allometric tree- and stand-level models of biomass and carbon mass.
