How is Unacceptable Growing Stock (UGS) defined?

• A. A tree with poor form or a species that does not satisfy landowner goals
• B. A tree with excellent form
• C. A tree with high timber value
• D. A young, vigorous tree

Answer: (A)

Unacceptable Growing Stock is all trees that don’t fit the stand’s intended future condition because of poor form or because the species doesn’t align with the landowner’s goals. In practice, these trees won’t contribute positively to the planned crop and are often targeted for removal to improve growth and value of the desirable stock. That’s why the definition you’re looking for describes a tree with poor form or a species that doesn’t satisfy landowner goals. Trees with excellent form, high timber value, or those that are young and vigorous are typically considered acceptable growing stock because they are likely to meet future timber production or management objectives.
