In the stocking example, which site has the higher site index?

• A. Site 1
• B. Site 2
• C. They have the same site index
• D. Not determinable

Answer: (A)

Site index measures how tall the dominant trees of a species are expected to be at a standard reference age, reflecting the site’s productive potential. In the stocking example, the trees on the first site reach a greater height than those on the second site at that reference age. Since site index is based on height at that standard age, the first site has the higher site index. This indicates better growing conditions for height growth on that site. Stocking or current age doesn’t change the site index concept; it’s about the potential height at the reference age.
