The Katunggan it Ibajay (KII) Eco Park is home to one of the most diverse mangrove forests in the Philippines. It is a 44.22 hectares protected park in the town of Ibajay in Aklan which boasts a total of 28 true species of mangroves or 80 percent out of the total 35 Philippine mangrove species. The forest is also a home to some species of birds and other wildlife like mud lobsters, fiddler crabs, mudskippers and other fauna. Recent studies have been conducted in the area which includes the identification of mollusk species, behaviours and activities of fiddler crabs. However, there is a lack of information on studies regarding Carbon storage and sequestration potential of mangrove species in KII. Therefore, considering the vital role of mangrove species there is a need to conduct this study to provide a wide array of information about the total C-stock and sequestration potential of selected mangrove species in KII. Likewise, it will help local folks, LGU-officials and future researchers to increase their awareness to protect and preserve KII Eco-Park; to help reduce increasing negative impact of global warming in the environment.

5. Specifically, it attempts to:
1. Determine the population density of mangroves
species in every sampling plot.
2. Quantify the amount of Carbon Concentration in
terms of:
a. Soil bulk density
b. Percent carbon concentration (POC)
c. Carbon Mass
d. Total Carbon dioxide (CO2) equivalent
3. Compare carbon concentrations of mangrove
species in the area.

6. Scope and Limitations of the study
This study will be conducted at the
Katunggan It Ibajay (KII) Eco Park in Barangay
Bugtongbato, Ibajay, Aklan from November to
January, 2015. This study will be focused on
the population density and its carbon
sequestration of selected mangrove species of
every sampling plot in 44.22 hectare in the
area.

8. Review of Literature
Global distribution of mangroves
O Climatic factors such as temperature and
moisture affect mangrove distribution. In some
areas, coastal processes such as tidal mixing and
coastal currents may also influence mangrove
distribution through affecting propagule dispersal
(De Lange and De Lange 1994).

9. O Human threats to mangroves include the
overexploitation of forest resources by local
communities, conversion into large scale
development such as agriculture, forestry, salt
extraction, urban development and infrastructure,
and diversion of freshwater for irrigation (UNEP
1994).
O Carbon sequestration in mangroves Mangrove
plantation is expected to be one of the options of
afforestation as a Clean Development Mechanism
(CDM) project.

10. Methodology
Materials
The materials used in this study were in the
following: meter tape, stakes, meter string, field
guide, clipboard or data forms, camera, ruler, peat
auger, hand shovel, sealed sample bags, paper
plates, oven microwave, digital weighing scale,
marker pens, ball point pen, plastics.

11. LOCALE OF THE STUDY
Katunggan It Ibajay (KII) Eco Park located at
Barangay Bugtongbato, Ibajay, Aklan
total land area of 44.22 has having a diverse 27
true mangrove species growth in its natural habitat.

12. Experimental Design
Non-destructive quadrat sampling technique to determine the
species density and structure in the study area.
Five (5) sampling sites measuring 10m x 10m (100m2) will be
randomly distributed in the area.
Plot 1: Avicennia rumphiana (Bungalon/api-api)
Plot 2: Rhizophora apiculata (Bakhaw lalaki)
Plot 3: Nypa fructicans (Nipa)
Plot 4: Avicennia marina (baras-baras)
Plot 5: Camptostemon philippinensis (gapas-gapas)

13. Methods
A. Site selection.
Only five (5) selected mangrove species will be
included in the study because of the following
reasons: (a) high number of species gown in the
area, and (b) they grow in clustered
population/distribution.
B. Laying out of quadrats
Five quadrats measuring 10 x 10 meters
(100m2) each will be randomly distributed in the
area based from the location of selected mangrove
species

14. Methods continued...
C. Calculating Population Density
The density will be calculated using the formula:
Dpop = N/A
where Dpop is the population density, N is the
number of mangrove stand, and A is the area (m2).

15. Methods continued...
Soil Sampling
Three (3) soil samples in each sampling plot
(depth of 20 cm) using peat auger.
Total of fifteen samples.
Soil Analysis
 Bureau of Soil and Water Management (BSWM)
Diliman, Quezon City.
Carbon-Nitrogen-Sulfur Analyzer.

16. Methods continued...
Carbon Calculation
Soil Bulk Density. To compute the bulk density
of the soil, the formula will be used:
D = W/V
Where W is the weight in grams (g) and V is the
volume in cubic centimetres (cm3).

17. Methods continued...
Percent Organic Carbon (POC). Soil Percent
Organic Carbon content was then multiplied by the
corresponding bulk density of each sample and soil
depth to obtain total soil Carbon storage per unit
area.
Carbon Mass. To calculate mass of carbon, two
methods of calculation formula will be used
(Donovan, 2013):
(1) CT = CF x D x V
(2) T = Thcm x D x Cpercent

18. Methods continued...
Total Carbon Dioxide (CO2) equivalent. This
will be obtained based from the conversion equivalent
suggested by Donovan (2013) where tons of Carbon
will be multiplied by 3.67 to get tons of Carbon
dioxide (CO2).

19. Methods continued...
Statistical Tools and Analysis
Frequency count
Ranking
ANOVA (set to 0.05 alpha level)
to compare the differences of carbon stock of each
mangrove species.
