This paper presents a general data model for forest inventory and management. The data model is based on the entity-relationship model and it can be implemented by relational database management systems. The data model can be used for inventories based on various kinds of sampling designs, and for different forest resource management systems from a forest stand to a national level. The data model supports data needs of complex forest surveys and integration of modules of forest information systems (geographic information systems, database management systems, computation, graphical user interface). The data model can be also applied to other natural resource data management cases.
