## Equations from this source (3)

### Commercial stem biomass from DBH and wood density (MB1)

Stem biomass for 20 commercial tree species of a managed forest (DBH >= 50 cm), Brazil. Inputs: DBH + Wood density. DBH 50.4–149.9 cm. 223 trees.

As printed (Table 1, MB1 (Chave et al. 2005 form)):

> ln(B) = β0 + β1 ln(d) + β2 ln(p) + ε

### Commercial stem volume from DBH, Husch log model (MV1)

Stem volume for 20 commercial tree species of a managed forest (DBH >= 50 cm), Brazil. Inputs: DBH. DBH 50.4–149.9 cm. 223 trees.

As printed (Table 1, MV1 (Husch 1963; logarithmic)):

> ln(V) = β0 + β1 ln(d) + ε
