Expanding recreational use of forest parks can strongly effect on natural resources and the quality of visitor experience. Deciding how much recreational use can extremely be adjusted in a park is stated by the concept of Carrying Capacity. Evaluation of Carrying Capacity as a management tool for forest park management in the North of Iran was presented in this study. Four factor including tourist flows, the size of the area, the optimum space available for each tourist and the visiting time were employed for evaluating physical Carrying Capacity. Results showed that the physical carrying capacity should be 54.8 ha 320visitors\day and real carrying capacity should be 31.6 ha 177 visitors\day. When total visitors to the park in 2012 were 220 visitors per day that actual average park visitation are higher than the estimated Carrying Capacity. The expanding recreational use would also unfriendly affect production and other forest benefits in long term. Therefore this study suggests that a recreational forest use plan must be adjusted by the planner to keep the park from heavy use and also optimum number of people without an unacceptable change in physical environment (Carrying Capacity) can be applied for ecosystem management, keeping of the high quality and quantitative of forest park and securing the ecological benefits stable for future.
