The subject of the Rájec project (the Drahanská vysočina Upland) consists in the analysis of ecological impacts of intensive management in spruce monocultures growing on original sites of beech. Long-term studies were aimed at particular stand and environment stages after clear-felling regeneration and at the origin of a spruce monoculture of the 2nd generation. The establishment of the spruce monoculture can be considered to be most important. The highest attention was paid to the monoculture both from the aspect of carbon and nitrogen in particular components of the forest stand and their transport processes as well as from the aspect of water regime and biodiversity. The study was also aimed at the first stage of the clear-felled area development after felling a mature stand and also at functions of the herb vegetation, which reached its maximum production 4 to 7 years after felling. The paper objective was to assess spruce monocultures even outside their natural range from the aspect of changes in the forest environment as well as from the aspect of possible global changes of climate.

Norway spruce is one of the most economically important coniferous species in Europe, but it has faced high mortality rates in the last few decades due to the increasing frequency of extreme weather events. Primary and secondary growth development may be affected by these non-optimal conditions. In this study, we aimed to analyze the timing, possible asynchrony and time-lag between the growth processes of Norway spruce. We used a novel methodological approach of primary (based on phenocamera picture evaluation) and secondary (dendrometers) growth detection. The combination of these novel approaches allowed us to compare these growth process in high temporal resolution. Measurements were performed in two experimental plots with contrasting climatic conditions (middle and higher elevations) in the years 2016–2019, during the presence of extreme climatic conditions. We demonstrated a significant elongation of the growing season, with a more pronounced effect at higher elevation. Compared to the long-term mean, we observed an additional 50 days with a temperature above 15 °C at the higher elevation plot. There were no found patterns in the time-shift of both growth processes between plots. On the other hand we observed asynchrony of radial growth and meristems growth. Radial growth began earlier than the phenology of apical meristems growth. The onset, end and duration of meristem growth differed between studied plots and years as well. The onset of radial growth did not follow the gradient of microclimatic parameters; however, the differences in climatic conditions between plots did cause a shift in the onset of meristem growth. The process of the radial growth was twice as long as for apical meristem development. On average, radial growth requires 71 days more than meristem phenology to reach full process completion. Our data confirmed that these growth processes are strongly affected by external weather conditions and the duration of the growing season. More advanced and detailed monitoring of these processes can provide more accurate data of the health status of trees in the forest.

“…Recently, a trend of replacing the coniferous species with the broadleaved species (Bednář, Černý 2014), especially oak and beech, which are the two most economically important broadleaved species in the Czech Republic (Ministry of Agriculture of the Czech Republic 2012), has been established (Klimo et al 2000). The former focus of larger forest owners has been targeting mostly Norway spruce (Picea abies (Linnaeus) H. Karsten) and Scots pine (Pinus sylvestris Linnaeus), as a consequence of the former German forestry school from the beginning of the 20 th century and promotion of conifers due to sufficient increment, production characteristics, and favourable merchantability, even on some inappropriate sites (Klimo et al 2000;Dobrowolska 2006).…”

Stojanović M., Szatniewska J., Kyselová I., Pokorný R., Čater M. (2017): Transpiration and water potential of young Quercus petraea (M.) Liebl. coppice sprouts and seedlings during favourable and drought conditions. J. For. Sci., 63: 313-323.Increased frequency and intensity of drought events consequently affect oak high forests with the process of further decline, compromised growth and questionable natural regeneration. To overcome such difficulties, new adaptive strategies are required. Coppicing, as the oldest way of forest management, might provide some solutions. In our study two contrasting management systems, sessile oak coppice and high forest, were compared at the initial stages of regeneration and forest development. The transpiration of young oak sprouts and seedlings was monitored using sap flow systems during the 2015 growing season. The study of transpiration also included leaf water potential measurements during three measurement campaigns with contrasting weather conditions. Coppice sprouts transpired significantly more than seedlings on the individual tree and stand level during the entire growing season 2015; particularly large differences were observed during drought conditions. Coppice sprouts experienced lower water limitations due to the voluminous and deeper root system as indicated by leaf water potential results. Presented results attribute young coppices as one of the promising adaptable forest management types with a better adaptive strategy at the extreme sites under water limiting conditions.
