The paper analyzes the state of forest cultures with estimated wood quantity in the Republic of Srpska, which are state-owned and managed by the Public Forestry Enterprise "Šume Republike Srpske". These forest cultures cover a total area of 44,424.28 ha or 4.5% of the total forest area of Republic of Srpska. Tree species composition, volume by age class and volume increment were analyzed. It was found that most areas occupy the forest cultures of Norway spruce, Scots pine and black pine. The average volume of forest cultures owned by Republic of Srpska is 187.19 m3/ha, with an average volume increment of 9.8 m3/ha. The largest share of forest cultures was identified in the age group of 20-40 years. In this age class 32,008.41 ha or 72% of the total area of forest cultures was determined.
In most forest cultures, the adequate and timely silvicultural measures (thinnings) were not carried out, which negatively affected the stand quality. Forest management measures in the future should be geared to growth measures as preventative measures to improve the overall state of forest cultures. Particularly important crops are those older than ½ rotation age as forestry plans must define the length of rotation, future measures, and management goals.
