Our current goals in forestry involve safeguarding the land and environment, optimizing the forest's ability to absorb CO2, maintaining the health and integrity of forest ecosystems, and preserving biodiversity and landscape variety. Ensuring the long-term productivity, socio-economic viability, and environmental functions of European forests and woodlands, including coppice woodlands, is crucial. Addressing these challenges can be effectively achieved by utilizing a combination of various management methods. The main focus of this study is on traditional forms of management such as coppicing, grazing, and litter raking. To facilitate this research, designated plots were established within the Training Forest Enterprise Masaryk Forest Křtiny. These plots, where sheep grazing and litter raking have been implemented since 2018, are exceptional and provide exemplary illustrations of diverse coppice management practices in Central European coppices.

This one-year study focuses on the responses of a soil environment to the implementation of traditional forest management practices in oak-hornbeam stands with the following treatments: cut (C), cut + litter raking (CR), cut + grazing (CG), cut + litter raking + grazing (CRG) and control (Ctrl). The cut was conducted in 2018 through extremely heavy thinning. In autumn of 2017 and 2018, we sampled the soils, focusing on microbial functional diversity (FD) assessments using BIOLOG EcoplateTM. After one season, the FD was the highest in the Ctrl stand and the lowest in the CRG stand. Furthermore, we detected significant seasonal differences in soil reaction, nitrate nitrogen content, phosphatase activity and microbial biomass among the treatments. In particular, the Ctrl stand was defined via FD indices and biochemical and biological soil properties that contrasted mainly with those of the CRG stand defined by the content of mineral nitrogen forms. The soil properties did not differ substantially in the remaining treatments. Of the 31 carbon sources defining FD, 6 were treatment-specific (putrescine, L-arginine, L-serine, L-threonine, D-cellobiose and glycogen), while the remaining carbon sources mainly displayed either uniform high or low activity across the treatments., info:eu-repo/semantics/openAccess

Research Highlights: The influence of litter raking and livestock grazing on the development of juvenile sessile oak and European hornbeam sprouts as well as on sessile oak standards were studied. Such experiments are very rare, especially in central Europe where these activities have been prohibited for several decades. Little is known on how these ancient management activities affect tree growth. Background and Objectives: Traditional management practices in coppice forests such as grazing and litter raking have been abandoned, but have recently been studied as to whether these practices can substantially contribute to an increase in the species diversity of coppices. The important question is, however, how these practices influence the growth of coppice-with-standards. Therefore, this study focused on the effect of grazing, litter raking, and their combination on both sprouts and adult trees in a coppice-with-standards system one year after harvest. Materials and Methods: The experiment was carried out in the area of the Training Forest Enterprise Masaryk Forest Křtiny, Czech Republic, in a forest stand dominated by sessile oak and European hornbeam. We analyzed 132 oak polycormons, 132 hornbeam polycormons, and 163 oak standards. Results: The number of sprouts per stump was affected by the stump size and management practice: (A) coppice-with-standards, litter raking, and sheep grazing; (B) coppice-with-standards and sheep grazing; (C) coppice-with-standards and litter raking; and (D) coppice-with-standards), but not by tree species. The number of the sprouts as well as their height increased with the stump size. In contrast, grazing resulted in a smaller height of the sprouts while thinner sprouts were found under a combination of grazing and raking. When comparing the species, the oak sprouts were higher and thicker when compared to the hornbeam sprouts. The increment of standards increased after stand harvest. This, however, was not the result of grazing or ra, info:eu-repo/semantics/openAccess

Coppicing started in the Neolithic period and has been practiced throughout European history. This traditional silvicultural system was abandoned in many European countries during the 20th century. The Czech Republic now has a very low proportion of coppice woods (CW), as more than 1000 km2 CW were converted into high forests after World War II. Nevertheless, many CW were maintained as stored coppices, which could be the last remainders of ancient coppice woods (ACW) in the Czech Republic. Knowledge of area and distribution of stored coppices is currently missing in the Czech Republic, because they are recorded as high forests in forest management plans. Many stored forests are currently approaching the maturity age, with a high risk that these last ACW remainders will be lost; therefore, an inventory of ancient coppice woods is necessary. In our study, we develop an index of likelihood of coppice occurrence (COP) based on the distribution of habitats favourable for coppices, as well as on past and current occurrence of CW in the Czech Republic from 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., info:eu-repo/semantics/openAccess

Ancient coppice woodlands are forest stands of coppice origin with a long-term continual development and preserved typical natural and historic elements of old coppices. Significant natural elements in ancient coppices include polycormons of coppice shoots, pollard trees, trees with holes, dendrotelms, reserved trees, ecotones, glades and significant plant and animal species. Significant historic elements of localities with ancient coppices include archaeological monuments, boundary ditches and walls, boundary stones, boundary trees, myths and legends, sacral objects, old roads and paths, technical objects and plough land remainders. The paper presents differentiation of assumptions for the occurrence of ancient coppices in the territory of the Czech Republic using the COPF coefficient and examples of results from basic regional inventory (Kuřim region) and detailed local survey (locality Lebeďák) of coppice-originated forests. The extinction of the phenomenon of ancient coppice woodlands would mean irreparable impoverishment of the natural and cultural heritage., Za starobylé výmladkové lesy označujeme lesní porosty výmladkového původu s dlouhodobým kontinuálním vývojem a zachovanými typickými přírodními a historickými prvky starých pařezin. K významným přírodním prvkům ve starobylých pařezinách patří výmladkové polykormony, hlavaté stromy, doupné stromy, dendrotelmy, výstavky, ekotony, světliny a významné druhy rostlin a živočichů. Mezi významné historické prvky lokalit starobylých výmladkových lesů řadíme archeologické památky, hraniční příkopy a valy, hraniční kameny, hraniční stromy, pověsti a legendy, sakrální objekty, staré cesty a stezky, technické objekty a zbytky plužiny. V článku je prezentována diferenciace předpokladů výskytu starobylých pařezin na území České republiky s využitím koeficientu COPF a příklady výsledků základního regionálního (Kuřimsko) a podrobného lokálního (Lebeďák) průzkumu lokalit lesů výmladkového původu. Zánik fenoménu starobylých pařezin by znamenal nenapravitelné ochuzení přírodního a kulturního dědictví., info:eu-repo/semantics/openAccess
