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.

This research conducted in order to prioritize the effective criteria on development of medicinal plants cultivation in North Khorasan Province using Analytical Hierarchy Process (AHP) and Delphi methods. For this purpose, a list of effective factors offered to delphi group. Analysis of delphi process showed that among 23 offered factors 19 factors, had greater impact on development of medicinal plants cultivation. Hierarchy tree was drawn through grouping of 19 factors into four criteria including economic, promotional–educational services, cultural–social and supportive policies factors. The pair wise comparison questionnaires were then distributed among relevant researchers and experts of the province to get their opinions about the priority of criteria and sub– criteria. The questionnaires were analyzed using Expert Choice software. The result revealed that economic criterion with respective weight of 0.406 had the most impact among four criteria affecting the development of medicinal plants cultivation. The supportive policies (respective weight of 0.275), educational–extension services (respective weight of 0.193) and cultural–social factors (respective weight of 0.125) received the maximum towards the minimum priorities, respectively. The results of synthesis process showed that among the 19 factors, the guaranteed purchase and establishing of pilot fields of medicinal plants, farmers'' awareness of comparative advantage of medicinal plants, and the development of processing industries had the maximum towards minimum impacts on development of medicinal plants cultivation.
