density_table

Provides species-specific wood density values (t/m3) and species group
classification (conifer vs broadleaf) used in CNPF and Vallet biomass
estimation methods.

datasets

Provides tools for estimating forest metrics such as stem volume,
biomass, and carbon using regional allometric equations. The package
implements widely used models including
