Abstract:

The study aimed to determine the carbon stock in the biomass of trees and soil organic carbon (SOC) in public green spaces of Bacolod City and Iloilo City from March 2009 to May 2011 using Brown’s allometric equation. Data showed that Bacolod City Plaza had the highest carbon storage with 189.02 t/ha. This was followed by Capitol Park and Lagoon, 93.84 t/ha and Pana-ad Park and Stadium 56.12 t/ha. In Iloilo City, Plaza Libertad had the highest stored carbon in biomass with 250.88 t/ha, followed by Jaro Plaza with 116.95 t/ha and Lapaz Plaza with 75.77 t/ha. The average carbon stock per hectare showed that Iloilo had 147.90 t/ha which was higher than that of Bacolod City with 112.99 t/ha. Data on soil organic carbon (SOC) showed that Bacolod City Plaza had 42.93 t/ha SOC at 0 to 15 cm depth while Pana-ad Park and Stadium had 42.02 t/ha and Capitol Park and Lagoon with 34.71 t/ha. In Iloilo City, SOC at 15 cm depth, Jaro Plaza had 43.85 t/ha, Plaza Libertad had 43.24 t/ha and Lapaz Plaza had 37.76 t/ha. The Green spaces in Iloilo City at 0 to 15 cm depth had higher mean SOC content with 41.62 t/ha at 0 to15 cm depth compared to Bacolod City (39.89 t/ha). At 16-30 cm depth, the green spaces of Iloilo City had higher SOC (36.95 t/ha) compared to in green spaces of Bacolod City (30.85 t/ha).
