Which of the following is NOT a purpose of a Biltmore Stick?

A Biltmore Stick is a specialized tool primarily designed for forestry applications. It serves three main purposes: measuring tree diameter, estimating tree height, and calculating board feet. By using this stick, foresters can easily obtain measurements of a tree's diameter at breast height and can also make height estimates based on specific markings and angles provided on the stick.

Identifying tree species, however, is not within the functionality of a Biltmore Stick. This task typically requires knowledge of tree characteristics such as leaf shape, bark texture, and other morphological features that the stick does not assist with. Thus, while the Biltmore Stick is highly useful for measurement and estimation in forestry, it does not play a role in species identification.
