Impact of tree species replacement on carbon stocks in a Mediterranean mountain area, NE Portugal

Abstract. Tropical agroforestry has an enormous potential to sequester carbon while simultaneously producing agricultural yields and tree products. The amount of soil organic carbon (SOC) sequestered is however influenced by the type of the agroforestry system established, the soil and climatic conditions and management. In this regional scale study, we utilized a chronosequence approach to investigate how SOC stocks changed when the original forests are converted to agriculture, and then subsequently to four different agroforestry systems (AFSs): homegarden, coffee, coconut and mango. In total we established 224 plots in 56 plot clusters across four climate zones in southern India. Each plot cluster consisted of four plots: a natural forest reference plot, an agriculture reference and two of the same AFS types of two ages (30–60 years and > 60 years). The conversion of forest to agriculture resulted in a large loss the original SOC stock (50–61 %) in the top meter of soil depending on the climate zone. The establishment of homegarden and coffee AFSs on agriculture land caused SOC stocks to rebound to near forest levels, while in mango and coconut AFSs the SOC stock increased only slightly above the agriculture stock. The most important variable regulating SOC stocks and its changes was tree basal area, possibly indicative of organic matter inputs. Furthermore, climatic variables such as temperature and precipitation, and soil variables such as clay fraction and soil pH were likewise all important regulators of SOC and SOC stock changes. Lastly, we found a strong correlation between tree species diversity in homegarden and coffee AFSs and SOC stocks, highlighting possibilities to increase carbon stocks by proper tree species assemblies.

The study was conducted to estimate the biomass and carbon stock in the dominant tree species of the Kaptai National Park of Bangladesh. A total of 77 tracks and 308 plots were selected and all trees in each plot were measured to estimate the biomass following allometric equations. There were planted stand of Acacia auriculiformis, Dipterocarpus turbinatus, Gmelina arborea, Lagerstroemia speciosa, Swietenia macrophylla and Tectona grandis. Biomass and carbon stocks of these corresponding tree species were 35.03, 73.86, 23.52, 30.16, 44.49, and 42.67 mg/ha. The highest carbon stock per tree was in D. turbinatus (372.19 kg C/tree), followed by S. macrophylla (226.49 kg C/tree), T. grandis (215.06 kg C/tree), A. auriculiformis (176.56 kg C/tree), L. speciosa (151.19 kg C/tree) and G. arborea (118.54 kg C/tree), respectively. The findings of the study will be helpful for the estimation of carbon stocks in the forests of Bangladesh. Bangladesh J. Bot. 50(2): 365-371, 2021 (June)
