Since Agro forestry study is very limited in Iran, identification of traditional systems was necessary in order to develop a basis for such studies particularly in Kohkiloieh and Boyerahmad province, which has special situation. To achieve the objectives of this study, many travels were done throughout the whole province and important systems were found and their characteristics were recorded. The Carlowitz method (1989) for standard characterization of Agro forestry technologies was used as a base to characterize the information of these systems. However, this method was not very detailed nor completely compatible to the present situations in many cases. Thus, Carlowitz principles were extended and a new method was developed which was corrected in an irritable process, and the systems were characterized.
The book entitled Characterization, Diagnosis and Design, which provides some more insight on ICRAF s (International Center for Research on Agro forestry) approach to characterize land use, was also used for developing the method. The systems studied in Kohkiloieh and Boyerahmad were classified according to Nair (1985) who classified the Agro forestry systems to three major groups based on nature of components. Then, the systems were reclassified according to the climatic and ecological conditions as well as to the level of technology and Socio-economic criteria.
