“…An important aspect of SRWC, specifically the clones of G. arborea, was the biomass production in short spans of time (Zamora et al, 2015). According to several studies conducted in Latin America, an adequate biomass production at the age of two years in species in SRWC can range between 10 and 60 ton /ha Cabrera et al, 2016;Carmona et al, 2015). Therefore, based on the results of the clones of G. arborea commonly used for wood production but planted in SRWC in different spacings (Figure 3), the production can be deemed optimum, despite the relatively low tree survival in the system.…”

The first attempts to establish energy crops in the tropical region using short rotation species are premised on the utilization of clones for wood production. Therefore, the present study is aimed at examining the growth aspects (survival, diameter and tree height), leaf architecture (leaf area index [LAI], number and angle of the branches and sylleptic branches), biomass production, as well as biomass flow at the age of 24 months of two clones of Gmelina arborea in short rotation crops within three spacings (1.0x1.0 m, 0.75x0.75 m and 1.0x0.5 m). The results showed an increment with age, as the diameter increased from 3.00 cm at six months to 8.0 cm at 24 months, whereas the total height increased from 2.00 m at six months to 10.00 m at 24 months. Clone survival varied from 20 to 60 %, whereas the LAI, branch angle and sylleptic branches increased with age. The differences between clones appeared after 12 months. Biomass production was similar between clones, from 6 ton/ha at six months to 67 ton/ha at 24 months, with clone 2 showing greater biomass flow than clone 1. On the basis of biomass production results and the development of diameter as well as height, clone 1 is recommended for spacing 1.0x1.0 m and clone 2 for spacings 0.75x0.75 m and 1.0x0.5 m.

“…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%.

“…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].…”

“…However, these recommended rotations were put forward before 2010, when the concepts of high density and short rotations in SRWCs were not developed [43]. With the new concepts in SRWCs for densities above 5000 trees/ha, a rotation of less than 5 years is to be expected, as is the case of Populus [92,93], E. globulus [85], A. melanoxylum [87], and Gmelina arborea [51] (Table 2).…”

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.
