Vachellia tortilis

12 equations apply to this species, 12 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 0.73 g/cm³, estimated from 7 samples in 4 studies by the Global Wood Density Database v.2 (Fischer et al. 2026, CC BY 4.0).

  Not fully checked: Section 2.3.3 says M4 requires only stump diameter, whereas Tables 1, 5 and 6 and Fig. 4 include total height. This record uses the explicitly parameterized equation in Table 5; confirm the conflicting description with the authors before relying on it.
