Mangroves play an important role as a carbon sink and in mitigation of climate
change. This study aimed to assess the anthropogenic activities, water and soil quality,
mangrove diversity, and carbon sequestration potential of mangrove trees in the Kaingen
River, Kawit, Cavite. The sampling period was conducted from November 2022 to March
2023 with the established three sampling sites. The DENR Administrative Order (DAO)-
2016-08 was used as a standard for water quality parameters, except for phosphates which
used DAO-2021-19. The soil parameters were identified using the soil test kit from the
Bureau of Soil and Water Management (BSWM) and at the BSWM laboratory. Mangrove
species were identified using The Field Guide for Philippine Mangroves and were verified
by experts. The carbon sequestration potential was obtained using an allometric equation
for Southeast Asian mangroves. There are three mangrove species found in Kaingen
Riverine such as Rhizophora mucronata, Avicennia alba, and Xylocarpus granatum. Based
on species importance value Rhizophora mucronata is the dominant mangrove species. The
result for carbon sequestration of each mangrove species showed that Rhizophora
mucronata yielded the highest carbon stored (35.16 tC/ha) and carbon sequestered (128.92
tCO2/ha). Among all the sampling sites, site 3 yielded the highest carbon stored (30.76
tC/ha) and carbon sequestered (112.81 tCO2/ha) in Kaingen River. Overall, the results of
the study showed that Kaingen River can potentially store carbon at 71.89 tC/ha and CO2
sequestered at 263.62 tCO2/ha. This urges to practice conservation and protection measures
for the mangroves forest of Kaingen River.
