In inventory analysis, density refers to which of the following?

• A. The number of trees per acre.
• B. The board feet per acre.
• C. The basal area per acre.
• D. The height of the stand.

Answer: (A)

Density is about how many individual trees occupy a given area. In inventory analysis, density is expressed as stems per acre (or per hectare). This distinguishes it from volume measures like board feet per acre, which reports how much wood is present, and from basal area per acre, which sums the cross-sectional area of stems at breast height to reflect size and spacing but not the count. Height describes how tall the trees are, not how many there are. So the number of trees per acre best captures density.
