Abstract

In Slovenia, data on forest area are obtained within the framework of forest management planning and data of the actual agriculture and forest land use. The article shows the differences in the assessment methodology of forest cover and spatial structure of forests. In accordance with the concept of national forest inventories, the article suggests upgrading of the existing concept of forest inventories which, in the last decade, have been subordinate to forest management areas and differences in the economic role of forests. Based on a systematic sampling design with plots at the intersections of a 1 km grid, we deduced from orthophoto images that between 2006 and 2011 the forest cover in Slovenia was 61.1±0.7%. The article shows restrictions of orthophoto images usage and statistic concept of assessment, where the assessment subjects are groups of forest site types at the national level.
