It is based on the sustainable management of renewable natural resources and production of raw wood. It is therefore able of sustainable growth. The interest of the European Union is to build economy based on renewable natural resources, resulting in the need to pay increased attention to the development and support of the forestry. The aim of the paper is to evaluate the performance of forestry sector in the Czech and Slovak Republics for a period of five years. System of indicators measuring sectorial performance was set up to reach the goal. Obtained results in indicators have shown that the profitability and value added rate of Slovak and Czech forestry are at a high level and the performance is affected by high investment efficiency.

This paper indicates that the annual value of the ecosystem services such as water conservation, soil protection, carbon fixation, nutrient cycling, water purification, air pollution absorption and recreation provided by forests is not only worth millions of dollars, but also in per hectare terms much more than hitherto known. After estimating the value of ecosystem services, results are available to policy-makers and experts at a brainstorming and by using SWOT, conservational strategies for long-term management based on strengths, weaknesses, opportunities and threats were developed. Ecosystem services value for the Mazandaran Forest Reserve ranged from 14.2 to 14.8 million USD or about 6,676.9-6,785.6 USD.ha-1. Given these results, raising the society awareness of the negative impact of forest land use changes based on the functional value were proposed as conservational strategies to prevent the forest land use change. If these are accounted for, then governments and societies faced with the development versus conservation dilemma can create more understanding decisions and policies that will assist to conserve forests and the ecosystem services they provide, and thereby promulgate human well-being and sustainable development.

Liebl. coppice sprouts and seedlings during favourable and drought conditions Abstract: 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.

Don pine plantation Abstract: Time consumption and productivity of a Valmet 890.3 8 wheel forwarder were evaluated on an Australian radiata pine clearfell site with a slope of 21 to 45% (12 to 24°). Cycle time was significantly related to extraction distance. Productivity was significantly related to extraction distance and load volume. Slope did not have a significant effect on cycle time or productivity. Productivity was considerably greater than that for many published studies, which was likely to have been the result of many factors at the study site affecting load sizes and cycle times, including the large load capacity of the studied forwarder, larger mean log volumes, larger log volumes per loading stop, fewer log assortments, potentially larger forwarder grapple volume capacity, log lengths suited to efficient loading and higher travel speeds.

Abstract: The current revitalization of forest ecosystems in the Krušné Hory Mts. is carried out through: (i) spreading line windrows, (ii) chemical amelioration. The aim of this research consisted in: (i) assessing basic pedochemical characteristics of spread windrows, (ii) testing the effect of slow-release fertilizers from the Silvamix® series and dolomitic limestone on the root ball zone soil five years after application. The results of this study suggest that spread windrows are a suitable environment for forest species: with the only risk being extremely low P concentrations. Our results further show an increase in the amount of soil macrobioelements in the case of Silvamix® R and Silvamix® Forte, namely P over 125 and 85%; Mg2+ over 84 and 108%; base saturation (BS) over 44 and 40.7%, respectively, compared with a control. Having applied dolomitic limestone, an increase of BS (by 88%), Mg2+ (by 250%) and Ca2+ (by 37%) was observed; there was a reduction in the level of mobile Al3+ (by 25%) compared with the control. Stromfolixyl® application did not affect the chemistry of the soil environment.
