Growing stock variation in different teak (Tectona grandis) forest stands of Mizoram, India
The growing stock assessment of three different teak forest stands (Tuirial: 500 m asl, Sairang: 200 m asl and Phunchawng: 550 m asl) was done in 2006 in Mizoram, India. Five diameter classes were arbitrarily established for knowing the volume attribute data and population structure, viz. a (10–20 cm), b (20–30 cm), c (30–40 cm), d (40–50 cm), and e (50–60 cm). Results revealed that the density of the individuals among the studied stands varied from 280 stems/ha to 620 stems/ha. The average diameter of all the individuals ranged between 27.48 cm and 35.43 cm. Similarly, the average height was oscillated between 17.87 m and 22.24 m. The total basal area was recorded between 24.28 m2·ha−1 and 45.80 m2·ha−1. The maximum and minimum values of total growing stock under all the diameter classes were 669.01 m3·ha−1 and 284.7 m3·ha−1, respectively. The representation of population structure of different stands explained that the perpetuation of this species was ensured for a quite long time.
