fiadb.biomass

Aboveground biomass of live trees (at least 1 inch d.b.h./d.r.c.) for a state — a design-based FIA population estimate with its sampling error — optionally grouped, in imperial or SI units. A friendly wrapper over the FIADB-API: no attribute or evaluation codes required.

Kind: standard
Network: yes
