Predicted occurrence of ancient coppice woodlands in the Czech Republic

Abstract: Coppicingstarted in the Neolithic period and has been practiced throughout European history. This traditional silviculturalsystem was abandoned in many European countries during the 20th century. The Czech Republicnow has a very low proportion of coppicewoods (CW), as more than 1000 km2 CW were converted into high forestsafter World War II. Nevertheless, many CW were maintained as stored coppices, which could be the last remaindersof ancient coppicewoods (ACW) in the Czech Republic. Knowledge of area and distribution of stored coppicesis currently missing in the Czech Republic, because they are recorded as high forestsin forest management plans. Many stored forests are currently approaching the maturity age, with a high risk that these last ACW remainderswill be lost; therefore, an inventory of ancient coppicewoods is necessary. In our study, we develop an index of likelihood of coppiceoccurrence (COP) based on the distribution of habitats favourable for coppices, as well as on past and current occurrence of CW in the Czech Republicfrom historical maps. COP index values were then used to generate a map showing the relative likelihoods of occurrence of ACW, which can serve as a baseline to support the compilation of an ACW inventory and their mapping in the field. Our results can help prioritize forest areas to be inventoried based on their higher probabilities of ACW occurrence.
