Wood identification

Wood identification begins at the end grain.

Color and face grain are memorable but variable. A clean transverse surface can reveal pores, rings, rays and resin canals that carry stronger evidence.

Photograph a clean end-grain surface plus the face and edge grain.

Record source, region, odor and density separately. Photo identification cannot certify species, structural grade, toxicity or suitability for fire or food contact.

Three surfaces, different clues

01

End grain

The transverse surface can show pores, growth-ring transition, rays and resin canals.

02

Face grain

Flat-sawn or quarter-sawn figure helps describe the board but depends on how it was cut.

03

Edge grain

A second longitudinal view can reveal ring angle and repeated structure.

04

Context

Region, known source, weight, hardness and odor may narrow the candidate when recorded carefully.

Prepare a useful photograph

  1. Use a clean surfaceDust, finish and rough saw marks hide anatomy.
  2. Light from the sideSoft directional light helps pores and rays remain visible without glare.
  3. Fill the frameKeep the surface square to the lens and sharply focused.
  4. Add a wider board viewShow figure, knots, finish and condition separately.
  5. Keep provenanceWhere the wood came from may be more informative than color.

Why an app cannot certify a wood species

The USDA Wood Handbook explains that wood identification relies on characteristic cell patterns and may often reach only the genus level. Closely related species can have different properties. An atypical, decayed, finished or very small sample increases error.

Use a specialist when the answer matters

Consult a qualified wood anatomist, laboratory, structural professional or other relevant expert for trade, conservation, toxicity, food-contact, fire or load-bearing decisions. Do not sand or cut unknown material without appropriate precautions.

FIELD SAFETY

Identification results can be incomplete or wrong. Never rely on a photo or AI answer for edibility, toxicity, medical care, fire safety, structural use or another consequential decision. Confirm with a qualified expert.
