Species / Salicaceae
Salix nigra
12 equations apply to this species, 4 fitted on it directly. Each output lists them most specific first: fitted on this species, then on a variety of it, then pooled fits that included it, then its genus and its family. Within each step, equations the authors advised against go last, then those read from compilations; more trees come first.
Wood density 0.41 g/cm³, estimated from 17 samples in 4 studies by the Global Wood Density Database v.2 (Fischer et al. 2026, CC BY 4.0).
