Assessment of soil properties under degraded forests: Javor mountain in Republic of Srpska - a case study

This paper presents the main characteristics of soils under degraded beech forests on Mt. Javor and the possibility of the reintroduction of the spruce and fir that had been cut during previous negative human activity. Research into forest soil characteristics before reforestation is not common practice in the Republic of Srpska, and very often is not successful because it has not been established which soil environment conditions are most appropriate for a particular tree species. Soil degradation has been attributed to improper management and the unplanned deforestation of some parts of the Javor Mountain. Degraded parts were initially colonized by bushes and herbaceous vegetation, but despite this and due to the steep slopes, soil erosion has occurred. The restoration of degraded forests usually requires reforestation in order to reduce soil erosion and convert low to high forests. The aim of this study was the assessment of soil properties for the reintroduction of Picea abies (Karst.) and Abies alba (Mill.) on degraded parts of Mt. Javor, as one of the ways to protect the forest soil from erosion. According to the World Reference Base we determined the following soil types: Albic Acrisol, Dystric Cambisol and Mollic Leptosol. All analyzed soils can meet the demands of fir and spruce due to their characteristics
