# Juniperus virginiana

Cupressaceae. 20 equations apply. Each output lists them most specific first: fitted on this species, on a variety of it, pooled fits that included it, then its genus and family. Within each step, equations the authors advised against go last, then those read from compilations; more trees come first. The order shows how specific the evidence is, not which equation predicts best.

Wood density 0.51 g/cm³, estimated from 17 samples in 6 studies by the [Global Wood Density Database v.2](https://doi.org/10.5281/zenodo.16919509) (Fischer et al. 2026, https://doi.org/10.1111/nph.70860; CC BY 4.0).
