However, limited information exists about their contribution to carbon storage. This study examined nine parks in the second district of La Union. Data were collected through field surveys to identify and classify trees and palms, assess vegetation cover, quantify aboveground biomass and carbon stock using allometric equations, and evaluate relationships using Pearson’s Correlation. A total of 36 species were recorded, belonging to 12 families, with Arecaceae, Fabaceae, and Moraceae as the most abundant in the population. Among all of the recorded species, 58% of them are exotic. The study found that vegetation cover and carbon stock varied with other parks with Aringay having the highest values at 80.92% vegetation cover and 29,527.96 kg of carbon stock. Overall, the total carbon stock of all parks was estimated at 263,258 kg. A positive correlation was observed between vegetation cover and total carbon stock, species richness and species count, and park size and species richness. The results highlight the role of public parks in carbon sequestration, proving that public parks with greater vegetation cover and tree biomass serve as vital carbon sinks, emphasizing their importance for climate change mitigation.en-USThesis
