Wood Anatomy

Definition

The microscopic cellular structure of wood, including vessel arrangement, ray type, fibre dimensions, and parenchyma distribution. These features are species-specific and form the basis of forensic wood identification, which is used in illegal logging investigations and physical evidence analysis.

Common questions

How does wood anatomy identification work when a sample is just a small chip or splinter?+

An examiner sections the sample thin enough to view under a microscope and compares the cellular arrangement, such as vessel and ray patterns, against reference atlases or known-species samples, a technique that works even on fragments too small for visual species identification by eye.

Why is wood anatomy particularly useful in illegal logging cases compared with other timber evidence?+

It can identify the species of a seized or processed timber sample even after the wood has been cut, milled, or partially manufactured, when bark, leaves, and other whole-tree identifying features are no longer present.
