wood
Let an agent handle wood by species, properties, grade, treatment and legality of source.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent handle wood by species, properties, grade, treatment and legality of source.
The hard fibrous material of the trunks and branches of trees and shrubs, used as fuel, building material and raw material for paper and products.
What it is for: Construction, furniture, fuel, paper and crafts.
It can be cut, shape and join it; dry and treat it; grade it, for strength; certify its legal and sustainable origin.
Distinguishing features
Natural, anisotropic material
Hardwoods and softwoods differ
Properties change with moisture
Legality of source is regulated
What it looks like
Grain patterns, colours from pale to dark; sawn timber, logs, boards and panels.
Physical character
density: 150-1300 kg/m3 - balsa to lignum vitae
moisture content for use: 8-20 percent - depends on use
How it is recognised
