Abstract
There is a lack of research on beech forests in Slovenia, despite the fact that beech communities dominate much of the total forest area, and that the total growing stock is increasing significantly. This research proposal encompasses five topics (work packages), which focus on important aspects of beech forests in Slovenia. The first one deals with the spatial distribution of beech in Slovenia, including spatial and temporal dynamics. The analysis is based on data from 215550 forest compartments, which provide the basic information and spatial units of this research. The second topic focuses on the stand structure of beech forests, with a stress on stand density. The analysis of stand structure is based on data from approx. 40000 permanent sampling plots (500 m2 each). The results will be analysed per site strata and developmental phases, and will be compared to reference values. The comparison will provide a basis for the improvement of beech forest management. The third topic involves natural regeneration of beech stands in different sites in managed and un-managed forests, and will focus on light conditions and architectural characteristics of regeneration. The results will serve as a basis for various regeneration techniques of beech stands in different site conditions. The fourth topic examines the appearance and abundance of red heartwood in beech trees with regard to tree age, diameter at breast height, growth dynamics, and crown characteristics. The results from each sub-topic will be compared and synthesized, and will be used to develop recommendations for improved forest management.
Significance for science
The research project brings new knowledge in the field of beech ecology, its spatial distribution, growth and stand characteristics, and regeneration. The following findings could be emphasized: 1) the model of spatial distribution of beech in Slovenian forests, 2) spatiotemporal model of beech in Slovenia in last decades. The importance of later results is higher because the topic is quite impartant now and results are significant different if compared to the recent knowledge. 3) Multiple linear regression model of diameter growth of beech in Slovenia was made in regard to different site and stand variables; we are just working on the publication now. 4) Findings on beech growth and “red heart” appearance contribute to the current knowledge of this theme. 5) New findings – also for broader area, were made on crown morphology of beech saplings in gaps of different size and of different light abundance.
Significance for the country
Beech forest sites cover seven tenth of the whole forest area, therefore findings from the research project will be useful for the majority of forests in Slovenia. Some findings should be emphasized. 1) stand parameters of beech forests were analysed and described for the whole forest area in Slovenia. 2) Findings on developmental characteristics of beech forests as well of growth patterns in different forest types are relevant for understanding of current status of beech forests and for the adaptive forest management of beech forests in the future. 3) Some findings on stand structure of beech forests, e.g. those on stand density of medium-age stand, indicate silviculture and management problems, reflecting some concerns in recent forest management. 4) Model of diameter growth of beech might be useful part of forest information system. 5) many results, e.g. those on regeneration of beech in gaps of different size and light availability or those on factors influencing “red heart” appearance will change the current regime of beech forest management. 6) Scenarios of future development of beech stands indicate higher amount of available beech wood. 7) Based on the project new monograph on beech forests in Slovenia in now in process: significance, problems in possibilities for beech forest management will be discussed.
