Biomass Distribution Among Tropical Tree Species Grown Under Differing Regional Climates
This study presents results from species selection trials in Panama as part of the PRORENA project, which examined the most effective species and methods for Panamanian government-supported reforestation projects.
research goal & methods
In 2003, 16 native and 2 exotic species were planted in single-species plots with a 3m x 3m spacing of trees at two different sites (one seasonally wet, one more dry). All plots were thinned to 50% of their original density at two years after plantation establishment, and the thinned trees were measured for biomass and biomass partitioning.
conclusions & takeaways
For seven species, there were significant differences between the sites in biomass and biomass partitioning; the humid site had greater biomass than the dry site. At the humid site, Acacia mangium, Gliricidia sepium, and Diphysia robinioides achieved canopy closure (before thinning) by year 2. The study’s model for biomass was upheld based on the relationships of biomass to height and basal diameter, suggesting that for 1-3 yr old trees, the biomass equations can be useful as a predictor of biomass and potentially carbon storage for the tree species in this study.
