This paper examines forest management planning and its possible outcomes using linear programing (LP). More specifically, the most appropriate forest harvesting schedule was selected that can maximize the carbon sequestration in the current forest areas considering forest manager’s income. The LP model allows the managers to segment forests into cutting units under rotation basis logging activities. Through harvest prescription from LP, we derived the balanced age-class distribution that constitutes improved conditions for sustainable use of forest resource. However, the solutions from LP did not achieve normal forests with perfectly even aged distribution. Instead, it produced a left-skewed age-class distribution due to the cost restriction of management ruling out the achievement of a normal forest as an optimal solution. The results from our LP model also confirm that the forest management activities will enhance yearly carbon sequestration in forests for all scenarios compared to baseline, and the shorter rotation ages tend to call for more carbon sequestration and economic profit. However, it is difficult to ensure that 50 years rotation is the optimal rotation age for the target forests, since we do not consider the benefit of biodiversity conservation.
