  2. What inspection or identification is needed before machining, bonding, treating or selecting a recovery route? action

Evidence for intended use

Determine whether available evidence supports the proposed demand on the wood.

Performance and decision limits

What it is Filled

the hard fibrous lignified substance under the bark of trees

In scope

  • Identification of wood and the evidence supporting its botanical attribution
  • Grain, growth features, heartwood and sapwood, and their distribution within a piece
  • Moisture, dimensions and material behaviour under specified conditions
  • Natural features, damage, biological deterioration and residual soundness
  • Processing, treatment and exposure history affecting material suitability
  • Evidence supporting a proposed use, intervention or recovery route

Out of scope

  • Tree health, growth and management, owned by living-tree and forestry models
  • Bark, foliage, roots as organs and other neighbouring biological materials
  • Engineered wood products, whose adhesives, layups and product performance belong to product models
  • Furniture, buildings and other assemblies made from wood
  • Commercial transactions, land tenure and certification systems
  • Charcoal, ash, pulp and other transformed materials that require their own identities

Why it exists Filled

Enable an AI agent to recognise wood, assess its condition and suitability, and determine which uses or treatments are justified by the available evidence.

Distinguishing features Filled

  • Determine whether an exposed section has woody tissue beneath bark or anatomical features consistent with tree wood; colour and surface hardness alone do not establish identity.
  • Distinguish bark from underlying wood by examining their boundary and tissue structure rather than treating the entire tree exterior as one material.
  • Inspect transverse and longitudinal faces for tissue organisation consistent with wood; distinguish bamboo and palm material through botanical or anatomical evidence when appearance is inconclusive.
  • Check for bonded particles, fibres, veneers or lamellae: these indicate an engineered product whose constituent wood can be described here but whose assembly requires another model.
  • Where a surface imitates wood grain, examine an existing exposed edge or documented composition to distinguish solid wood from printed coverings and non-wood substitutes.

What robots and AI may and may not do Filled

Must not

  • Trade or use timber from illegal logging or protected species.
  • Burn treated or painted wood indoors or near people.
  • Cut or sand wood without dust control and protective equipment for workers.
  • Present a wooden structure as sound without inspecting it.

Only with a human decision

  • Felling trees or removing load-bearing timber.
  • Declaring wooden structures safe for use.

May

  • Identify wood species and grade timber from visible features and records.
  • Report rot, insect damage or moisture in wooden structures it is authorized to inspect.

Moral aspects Filled

  • Illegal logging destroys forests and the livelihoods of people who depend on them.
  • Wood dust harms the lungs of the people who work it.

Who is affected

  • Forest communities
  • Woodworkers
  • Occupants of timber buildings

Owners Filled

Steward

The owner of the forest or timber; forestry authorities regulate harvest and trade.

Master systems
