In this library's units, ready to compute (kg)
Aboveground biomass = 0.201 * D^2.173D- Diameter at breast height (1.3 m), cm
Dry biomass in kg. Adjusted R2 as printed: 0.94. Includes leaves (AB is stem with bark plus branches including foliage).. Fitted on dry-site beech; the paper also gives fresh-biomass and log-transformed variants (not added).
