As a part of International Cooperative Programme on Assessment and Monitoring of Air Pollution Effect on Forests (ICP Forests), defoliation of forest stands has been assessed in the Czech Republic since 1986. Defoliation is one of the principal parameters reflecting the health of forest stands that is assessed on monitoring plots within this programme. Monitoring plots are distributed evenly according to woodiness of the area in a regular schematic network all over the Czech Republic. Even though there has been a long-term reduction of air pollution in most European countries, forest ecosystems reflect these changes with some delay. In the Czech Republic...

The functional efficiency of forest stands planted on the heaps originated by black coal mining was resolved in the territory of the Moravian-Silesian region. The aim was to verify the possibility of applying the method of Quantification of Social Forest Functions for the purposes of evaluation of forest stands on anthropogenic substrates and the subsequent use of the method for quantification of social forest functions in the particular reclaimed localities. Potential functional capacities were evaluated as well as the current functional effect of the following functions: bioproduction, ecological, hydrological, soil-conservation, recreational and...

The effect of floodplain forest fragmentation on the bird community

J. For. Sci., 2012, 58(5):213-224 | DOI: 10.17221/123/2010-JFS  

The paper reports the results of a study focused on ornithocoenoses of floodplain forests in Litovelské Pomoraví locality (Czech Republic). The edge effect on diversity of the bird community is discussed and some implications for floodplain forest management are presented based on the results of investigations into changes in the bird community due to fragmentation of an originally continuous forest stand by regeneration felling, and the results of research into ornithocoenoses of the age-diversified mosaic of forest stands. Perforation of the continuous old floodplain forest by clear felling, which was investigated within this study, slightly increased...

Operational monitoring of the nun moth Lymantria monacha L. (Lepidoptera: Lymantriidae) using pheromone-baited traps - a rationalization proposal

K. Hielscher, A. Engelmann

The annual risk assessment of Scots pine (Pinus sylvestris L.) stands in the federal state of Brandenburg and subsequent decisions on the application of insecticides are based on operational surveillance data on L. monacha. The objective of the study was to rationalize the operational pheromone capture method. Data from operational monitoring with pheromone-baited traps in Brandenburg were analyzed. The records included data from a total of 11,761 traps and covered the development of populations of this insect from normal to outbreak densities and back during the years 2000-2009. Statistical analysis of the data suggested that a capture...

Cultivation of speckled alder under harsh mountain conditions

The aims of the paper were as follows: (1) to assess the applicability of speckled alder for pioneer stands on the mountainous clear-cut tracts and (2) to evaluate the effects of slow-release fertilizer on the survival and growth of speckled alder under harsh environmental conditions. On the basis of seven-year results we can presume that speckled alder is a convenient pioneer species that can be cultivated on harsh mountain sites where the climatic extremes need to be alleviated and a layer of surface humus renewed. The initial slow-release fertilization is, nonetheless, highly desirable. As contrasted to the control the surface and planting hole...
