Betula alnoides
11 equations apply to this species, 6 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.

General equations that may apply (18)
Fitted on many species across the tropics or the world, so not ranked against the ones above. Pantropical ones show only when this species's own fits come from the tropics, for the same tree type. Check that your trees fall inside each one's range before using it.
