Looking at the different stages of wood logging operations in north forest of Iran we will see that a huge amount of data is collected and in various traditional and digital methods are stored. Todays, despite the emergence of new database and databank systems, unfortunately, most of the General Natural Resource offices of Iran even in the northern provinces, do not have any comprehensive and smart information system and database so that massive amount of information from various stages of harvesting operations could be collected and stored efficiently. To facilitate in storage, processing and delivery of harvesting information of north forest, a harvesting database system using Entity – relationship data model was designed. Access software version.2016 was used to implement the entity- relationship data model or physical design of database system. The designed system includes several components or subsystems (marking of trees, cutting, re-measuring, grading, wood extraction from the forest field and depot, districts certification, forestry plans, forestry plans executives, and out of forestry plans cutting licenses). Using the designed system, the information and data requirements for further investigation and processing from forest harvesting data for forest management decision making can be provided.
