Equation

As printed (Table 3, BR Dry row)

BR Dry a 0.123 b 1.776 Adj-R² 0.79 N 66

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

Branch biomass = 0.123 * D^1.776

D: Diameter at breast height (1.3 m), cm

Dry biomass in kg. Adjusted R2 as printed: 0.79. Branch biomass includes foliage, so it is a branch plus leaves total.. Fitted on dry-site beech; the paper also gives fresh-biomass and log-transformed variants (not added).
