Abstract
This study is conducted to assess the amount of carbon stored in the above-ground biomass of the tree species at the Isabela State University Wildlife Sanctuary (ISUWS). A total of 34 different tree species were found with 285 individuals were identified with a total of 47.50 t/ha Carbon stock and 164.09 t/ha of accumulated CO2. It was found in the study that Alstonia scholaris contains the largest amount of above-ground biomass (AGB) with a mass of 20.97 t/ha and Carbon stock of 9.44 t/ha followed by Samanea saman with a mass of 13.40 t/ha and Carbon stock of 6.03 t/ha. Based on the result and conclusion of this investigation, the following recommendations were drawn: Conduct a study concerning the carbon emission of the area to determine the relationship with its carbon sequestration potential; and conduct tree planting activity to open areas in the study site to increase its carbon stock potential and fully serve the purpose of the area as a wildlife sanctuary.

After randomly choosing the coordinates of the base corner of sample plots, they were located with the used of Global Positioning System (GPS) and the base stake was placed on the ground
Summary
Global warming is among the most dreaded problems of this millennium which just represents one aspect of climate change. This is caused mostly by increasing concentrations of greenhouse gases in the atmosphere resulting in changes in climate pattern. Greenhouse gases (GHGs) which are primarily carbon dioxide, methane, nitrous oxide and others have influenced the earth’s climate system. Among the GHGs, carbon dioxide (CO2) is the most important and abundant gas in the atmosphere and is responsible for more than half of radiative forces along with the greenhouse effect [2]. Forest ecosystem plays a very important role in the global carbon cycle by sequestering a substantial amount of CO2 from the atmosphere [3]. The Philippine forests in particular, through massive deforestation, were found to have contributed about 3045 tons of Carbon to the atmosphere since the year 1500 up to the present era [2]
