What does CAI measure?

• A. Growth from the previous year
• B. Growth in the current year
• C. Total growth since establishment
• D. Mean annual growth since establishment

Answer: (A)

Current Annual Increment (CAI) measures the amount a stand grows during a single year. It is the increase recorded from one year’s measurement to the next, i.e., the growth achieved in the current year relative to the previous year. This is why the best answer is growth from the previous year. CAI is not a measure of total growth since establishment (that would be cumulative) or mean annual growth over many years (that would be MAI). In practice, CAI shows how much the stand added in the most recent year, helping to track yearly productivity and the effects of management actions.
