“…Based on the production of several species utilized in SRCs in tropical areas [20,[51][52][53][54], an average biomass production can be established at 20 Mg/ha/year, that is, for a 3 year old plantation of G. arborea in an SRC system, like the one in this study, an average biomass production of 60 Mg/ha would be expected. Thus, considering the production of total biomass without leaves in the present study (Figure 3e), only two spacings (1.0 × 1.0 m and 1.0 × 0.5 m) in Location-1 at 3 years would exceed the optimum production of 60 Mg/ha for G. arborea in SRC systems.…”

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%.

“…The higher potential for volumetric growth per tree in the larger spacing is justified by the greater efficiency of the trees in the capture and use of primary resources, such as water, CO 2 , light, and nutrients, due to reduced competition Fig. 8 Functional relationship between heartwood diameter and total tree diameter (Costa et al 2015). Oppositely, in the closer spacings, root competition can reduce photosynthetic production and cause early tree senescence and mortality (Kopp et al 1996).…”

“…Tree spacing is one factor that affects development and yield in homogeneous plantations (Silva et al 2016) and should be tested to assure adequate supply of biomass by new species. Moreover, the wood should be suitable for the conversion processes of biomass into energy, as measured by its basic density, chemical composition, and HHV (García et al 2012;Costa et al 2015).…”

spacings (6.0 m 2 and 7.5 m 2 ). Genetic variability of the T. vulgaris seed stand and/or high heritability of wood traits overcame the effect of different spacing on all morphological, physical, chemical and energetic properties of T. vulgaris wood. This species has moderate basic density when cultivated at spacings larger than 6 m 2 and net heating value above 7.95 MJ/kg, which is suitable for bioenergy purposes. The high variation in wood properties within tree spacing is strongly indicative of great potential for genetic breeding. The fast growth and the suitable moderate wood basic density confirm the outstanding potential of homogeneous plantations of T. vulgaris for providing wood for bioenergy.

“…Another important parameter related to production is the increase of the biomass, which for the few species reported is moderately high. For example, an increment of 9.2 to 11.5 Tn/ha/yr was found for Populus deltoides [93]; several species of Eucalyptus report a range from 17 to 50 Tn/ha/yr [87], from 18.1 to 33.4 Tn/ha/yr has been observed in Acacia mangium and Acacia auriculiformis in Brazil [83], and from 12 to 64 Tn/ha/yr was found for G. arborea in Costa Rica [52].…”

Studies related to biomass production, with a focus on energy uses for short-rotation woody crops (SRWCs), are limited in Latin America. The research that is available relates to a variety of tested SRWC species (50 species), however, the most important species are Populus, Salix, Eucalyptus, Acacia, and Gmelina arborea. In the existing studies, stocking densities varied from 1111 to 20,000 trees per hectare, with square or rectangular spacing. One important advantage of SRWC systems in this region, compared to most regions worldwide, is the predictability of biomass yields due to the tropical climate conditions of the majority of the Latin American countries. Rotations of three and four years can be projected to produce total biomass yields of 30–50 tons/ha, with increments of 10–20 tons/ha/yr. Fertilization is performed in SRWC with the aim of preventing soil degradation and maintaining further production. In regards to possible uses of biofuel generated from SRWC in Latin America, an inconvenience is that there are neither well-established harvesting systems nor conventional pre-treatments to process the biomass. Processes that are available in the region that use biomass from SRWC for energy production are gasification and pellet production. Other potential biofuel processes, such as torrefaction and biochemical conversion, are limited in this area.
