This manuscript presents a simulation-based spatial forest management planning model developed for ecosystem-based multiple use forest planning approach. The general framework of the simulation model was firstly introduced. It was then implemented in a typical forest management planning unit. Four forest management planning scenarios including nonspatial and spatial characteristics were developed. These scenarios were compared in the context of different forest performance indicators (such as allowable cut, growing stock, net carbon sequestration, age-class distribution at the end of the simulation). When compared the simulation-based forest management planning scenarios, it was found that there were no significant changes in timber production levels among scenarios. On the other hand, spatial forest management scenarios controlled forest ecosystem structure and produced more applicable forest management plans.

Spatial Decision Support System is indispensable to develop spatial planning alternative by integrating spatial parameters into forest management plans using ecosystem based multiple use forest management planning concept (EBMUFM). Spatial forest planning provides several opportunities to decision makers to generate spatially implementable harvest schedules and perform spatial analyses as part of integrated planning. This paper presents the role and importance of spatial forest planning in forest management, and evaluates it in the context of Turkish forestry. Basic concepts related to spatial forest planning are explained. Some important intuitive decision support techniques (modeling techniques) widely used in spatial forest management planning were introduced. Further, spatial decision support systems for forest management planning developed in various countries were provided. Finally, it is concluded that spatial forest planning is extremely needed in EBMUFM.

Decision Support Systems (DSS) is widely used to develop spatially explicit forest management plans through the integration of spatial parameters. As a part of this study, a simulation-based spatial DSS, the ETÇAPSimülasyon program was developed and tested in a case study area. The system has the capability to control the spatial structure of forests based on a geodatabase. Geographical Information Systems (GIS) was used to generate the database, using spatial parameters including opening size, block size and green-up delay in addition to other attribute data such as the empirical yield table and the product assortment table. Based on the simulation technique, a spatial forest management model was developed to link strategic planning with tactical planning on a stand base and to present results with a number of performance indicators. One important component of the model determined all spatial characteristics with spatial parameters and patch descriptions. A stand growth and yield simulation model (BARSM) based on the relationship between current and optimal basal area development was also generated to project future stand characteristics and analyze the effects of various silvicultural treatments. A number of spatial forest management strategies were developed to generate spatially implementable harvest schedules and perform spatial analyses. The forest management concept was enhanced by employing a spatial simulation technique to help analyzing the ecosystem structure. Spatial characteristics for an on- The-ground forest management plan were then developed. The model was tested in Altinoluk Planning Unit (APU) using a spatial simulation technique based on various spatial parameters. The results indicated that the spatial model was able to satisfy the spatial restriction requirements of the forest management plan.
