Adapting the tree growth model MOSES to manage uneven-aged mixed species forests in Bosnia & Herzegovina

Abstract

In Bosnia & Herzegovina, uneven-aged Plenter forest is the dominating forest management system and applied to 90% of the high forest area. This differs from most other European countries, where even-aged forest management is dominating. However, the interest in Plenter forest management is increasing, as mixed diverse forest stands are considered to be more resilient versus even-aged forests. In this study, we analyze uneven-aged forest management in Bosnia & Herzegovina and demonstrate the application of the tree growth model MOSES (Modeling Stand rESponse) for Plenter forest management in the region. After validating the model using independent data, we perform simulation scenarios to demonstrate the applicability of the model to the local conditions. Our results suggest that the model exhibits no bias or inconsistencies in the resulting predictions. The simulation runs show how the model can be used for scenario analysis within Plenter forests and that continuous management is needed to maintain the diversity of Plenter forest ecosystems.
