The paper deals with the determination of the amount of logging residues including merchantable timber volume (brush) left in the beech stands for further use. Logging residues were recorded in all types of intentional felling starting with intentional improvement felling up to 50 years and ending with intentional regeneration felling. The potential amount of biomass left was divided into the share of brush and the share of small wood. The parameter was monitored for 3 years and all measured values were then statistically evaluated and related to 1 m3 of intentional felling in beech stands. A partial goal of this publication is characterization of...

This paper presents a spatial-based decision support system (DSS) to assist public and private forest managers in the analysis of potential feasibility in payments for forest ecosystem services (PES) for the prevention of soil erosion. The model quantifies the maximum willingness to pay (WTP) of managers of a reservoir to prevent soil loss. The minimum willingness to accept (WTA) of forest owners for the activation of a private market is also computed. The comparison of WTP and WTA identifies the forest area where PES are ideally feasible with additional potential for compensation to enable the schemes. The DSS highlights forest idiosyncrasies as well...

Control and supervision activities in the field of forest management are a type of activity of state authorities to detect, prevent forest violations. The purpose of this study is to analyse the dynamics and nature of violations in the forest sector on the example and in comparison of such regions of Russia as the Krasnodar territory and the Republic of Bashkortostan. The research methodology is selected taking into account the characteristics of the object under study. With the assistance of employees of the environmental inspectorate, search operations were organized in the areas where the greatest amount of forest damage occurs in the studied regions....

Understanding the forest response to ongoing climate change is crucial in forest management strategies under anticipated climate adversity. To understand the retrospective growth dynamics of Jeffrey pine (Pinus jeffreyi Grev. & Balf.), tree-ring chronology from the subalpine forest in the Lake Tahoe Basin, California was correlated with air temperature, precipitation, and Palmar Drought Severity Index (PDSI). The years 1757, 1782, 1886, 1859, 1876, 1920, 1929-30, 1977, 1988-89, 2001-02, 2008, and 2014 were some of the years with noticeable low growth. There was robust growth in 1747-49, 1792, 1828, 1866-68, 1913, 1969, 1984, 1998, and 2011. Ring...

Structure of black walnut (Juglans nigra L.) stands on sandy soils in HungaryShort Communication

J. For. Sci., 2021, 67(6):298-305 | DOI: 10.17221/205/2020-JFS  

Understanding the various processes and relationships that take place in forest ecosystems is generally possible only through long-term observations. This is especially true of the biological production of forests, through the in-depth exploration of their structure. In Hungary the black walnut (Juglans nigra L.) is one of the most valuable exotic tree species, mainly because of its very valuable wood, with fine tissues and unique colour, for furniture industry. Generally, the species is established by manual seeding, and can also be regenerated well by coppice shoots, but not by natural seeding. Black walnut regularly produces seeds from the age of...
