Abstract/Summary

Global warming is now considered one of the most serious environmental problems brought about by the excessive emissions and accumulations of greenhouse gases (GHG) in the atmosphere with carbon dioxide being the most detrimental. At present, this phenomenon is already inevitable but mitigation can still be done through the regulation of GHGs emissions from several sources. Terrestrial ecosystems like forests have the ability to absorb carbon dioxide from the atmosphere and use it for their growth and food production via the process of photosynthesis. This study therefore aims to estimate the carbon sequestration potential of two land-uses namely, secondary forest and mango + coconut multistorey agroforest stand inside Salikneta Farm-De La Salle Araneta University – Agrivet Science Institute in San Jose, Del Monte, Bulacan. To accomplish this, a one-hectare sample area was laid-out in both sites and followed by the measurements of diameter at breast height (dbh) and tree height for all trees above 5cm dbh. Soil samples were likewise collected for soil bulk density and percent soil carbon determination. The data gathered from tree measurements were plugged in the biomass allometric equation published by Chave et al. (2014). Results of soil carbon density and tree carbon density were combined to provide a complete estimate of the potential of a particular stand of its carbon stock. Total carbon density and total carbon sequestered were estimated and the values for both stands were subjected to t-test. With a value of 73.630 MgC ha-1 in secondary forest and 60.084 MgC ha-1 for Ma+Co multistorey agroforest stand for total carbon density, analysis suggests that no significant difference exists between the two land-uses. Similarly, there was also no significant difference between the two land-uses in terms of potential carbon it can sequester with values of 269.977 MgC ha-1 and 220.308 MgC ha-1 for secondary forest and agroforest, respectively. With regard to the most dominant vegetation in both stands, Ficus nota and Bursera graveolens were found to be the most dominant species in multistorey and secondary stands, respectively, thereby suggesting that these species must be properly conserved in the area to maintain its potential for carbon dioxide sequestration. On the other hand, Mangifera indica and Delonix regia registered the highest carbon stored in its biomass in multistorey agroforest stand and secondary forest, respectively, hence, they are also recommended to be conserved by the Salikneta management.
