Trends of Forest Harvesting Ages by Ownership and Function and the Effects of the Recent Changes of the Forest Law in Hungary

To determine the optimum time to harvest trees is one of most interesting problems in economics forest resources. It highly debated whether forests Northern hemisphere should be used as carbon sinks or harvested more for long- short-term wood use storage long-lived products and bioenergy. In our study we examined trend cutting ages by tree species, ownership function period 2006–2021 based on data National Forestry Database (NFD). We also any changes effective rotation linked change Hungarian Forest Act 2017 could observed. concluded that there were two main sub-groups case which different trends applied. state-owned indigenous species with a long period, actual harvesting had an increasing last fifteen years, while some short periods lower levels naturalness, private decreasing trend. The black locust (Robinia pseudoacacia) showed significant decrease production between years 2016 2021. This implies since permissive regulation, management stands has moved towards economically profitable 20 cycle. new can regarded important step separation functions, means role high nature conservation value protect biodiversity, provide ecosystem services mitigate climate through trees, dead soil, plantations level naturalness timber climate-friendly resource, contribute mitigation long-term products, wooden buildings substitution fossil fuels.
