Sažetak
Written documents dealing with afforestation activities and the establishment of the first forest cultures date from the early 19th century. Extensive afforestation operations in the continental part of Croatia began around 1960 with planned and organised work aimed at increasing the proportion of conifers in the forest fund. At that time specialist or scientific knowledge concerning the establishment and growth of intensive forest cultures and plantations was scarce. An institute was established in Jastrebarsko with the basic goal of creating and integrating scientific-research results of this issue. Continuing research has since been conducted in permanent field experiments established and distributed in different site conditions across Croatia. A total of about 75,330 ha of conifer cultures have mostly been established in bracken and heath areas and in abandoned agricultural areas and pastures. The paper presents an overview of conifer cultures and provenance tests established by the Department of Ecology and Silviculture in terms of tree species, area, age structure, localities and representation per Forest Branch Offices of the company "Hrvatske šume".
