“…Despite the increase in diameter and height in trees of Location-2, Year 3, these seemed to continue their normal growth, since the high mortality observed in this location at the age of 2 and 3 years influenced the development of height and diameter of the trees at the age of 3 Years. According to Marsh and Burgers [46], stands with clearings, such as those of SRC systems due to mortality, present similar growth to stands established using lower planting density, which is a reason why growth was influenced by the low density of the plantation present in the trees of Location-2 during those years ( Table 3).…”

Mortality, diameter at 30 cm over ground level, height, biomass production, and carbon capture (CC) for different tree components (trunk, bark, branches, and leaves) in two locations in Costa Rica, during their first three years and with three plantation spacings (1.0 × 0.5 m, 1.0 × 1.0 m, and 1.0 × 2.0 m) were obtained for Gmelina arborea Roxb. trees growing in short rotation coppice systems (SRC). In addition, regression models were developed to predict biomass production and CC using location, age, spacing, and their interactions. Biomass production was measured by weight of trees without considering dendrometric variables. Results showed that mortality was lower than 15% for one location, with probable high fertility, and almost 85% for the other location. Diameter and height of trees increased with plantation age in both locations. The highest biomass production and CC were observed in the spacings of 1.0 × 0.5 m 2 and 1.0 × 1.0 m 2 , with 20 Mg/ha/year and 8 Mg/ha/year, respectively. The models to predict biomass production in trunk with bark, branches, leaves, total biomass without leaves, and CC in trunk, branch, and total biomass were developed using this equation: Y = β 1 + β 2 (location × age) + β 3 (age) + β 4 (spacing). The R 2 values varied from 0.66 to 0.84, with error from 0.88 to 10.75 and indicators of goodness of fit from 60 to 83%.
