Abstract:Net change in volume (V) from time 1 to time 2 can be attributed to the components of ingrowth (I), survivor growth (S), mortality (M), and cut (C) (Beers 1962) as follows: V2 - V1 = I + S - M - C. Traditional point sampling methods for estimating the right-side growth components often lead to an inequality with the left-side estimate of net change. This paper shows concisely why this occurs. A new estimator for survivor growth is developed which ensures equality between estimates of net change and the components thereof. Forest Sci. 32:415-422.
