ABSTRACT
Mangrove forests play a crucial role in the environment by serving as nurseries for marine life and protecting coastlines from storms. Nonoc Island has no data in terms of mangrove diversity and carbon storage in the DENR. This study assesses diversity and measures carbon storage in trees and soil in the mangrove forests of Barangay Cantiasay and Barangay Nonoc, Nonoc, Island. Field sampling was done on September 15-17, 2023, where the transect-quadrat method was utilized, with 15 plots per site established to assess mangrove species composition, biomass, and soil carbon. Species identification was based on morphological characteristics, and diversity indices were analyzed using PAST software. Aboveground biomass (AGB) was estimated non-destructively, while soil samples were collected from depths of 0鈥�30 cm and 30鈥�60 cm for carbon content analysis. A total of 306 mangrove individuals from six species were recorded and were classified as Least Concern by the IUCN. Rhizophora species were the dominant species in both sites. Rhizophora apiculata had the highest tree biomass (6,493.17 kg and 1,569.60 kg) and carbon storage (3.12 Mg ha-1 and 0.737 Mg ha-1) in Cantiasay and Nonoc, respectively. Soil carbon estimates totaled 84.86 Mg C ha-1. The highest total carbon stock was recorded in the mangrove forest of Cantiasay (251.09 Mg C ha-1), with 85% stored in sediments, while Nonoc had 152.24 Mg C ha-1, with 95% stored in sediments. These findings highlight the vital role of mangrove forests in carbon storage and their contribution to the reduction of carbon dioxide deposits.
