Fagus moesiaca stump dry biomass from diameter at 30 cm (Fig. 1)

Stem biomassFagus moesiacaGreecenaturalRead from the original paperPeer-reviewed sourceNot fully checked

Not fully checked: Figure 1 supplies no SEE or correction factor and does not identify whether 0.1954 includes the log-back-transform correction discussed in Section 2.3. This record uses the printed curve; verify correction handling before treating its output as mean stump dry mass.

Equation

As printed (Figure 1, p. 443 (rendered page))

M_SP = 0.1954 D_B^0.9788

In this library's units, ready to compute (kg)

Stem biomass = 0.1954 * D30^0.9788

D30: Stem diameter at 30 cm, cm

DB is diameter at 0.30 m above ground, mapped to D30. Stump mass only, not whole-stem biomass. The printed equation is used as shown; no additional correction can be calculated from the Figure 1 information.
