XII. World Forestry Congress have been held in Quebec, Canada from September 21 to 28, 2003. Forestry issues were discussed on three basic areas: Forests for People, Forests for the Planet, People and Forests in Harmony. The Czech Republic was represented by 9 contributions.
National Forestry Programme of the Czech Republic in brief
K. Vančura
J. For. Sci., 2004, 50(11):500-504 | DOI: 10.17221/4646-JFS
The basic principle from which the Czech National Forestry Programme proceeds is the management of forests in a permanently sustainable manner whilst limiting the administrative interference of the state to the unavoidable minimum under the circumstances of the motivating operation of state forestry policy for the support of public interests and whilst increasing the responsibility of forest owners for their property. The National Forestry Programme is supposed to be an interdepartmental and intersectoral programme respecting not only the needs for the branch development of forest management, but also emphasising the place of forests in the environment...
Development of the Czech forest related policy and institutions in the threshold of the 3rd millennium
K. Vančura, P. Pacourek, J. Řezáč
J. For. Sci., 2004, 50(11):505-509 | DOI: 10.17221/4647-JFS
This paper gives an overview of Czech forestry policy and legislation since the beginning of changes in the CEEC plus developments and activities of the main forestry institutions. These activities are referred to in the background material given for the political transition period and also related to the Pan-European and global forestry processes. The philosophy of forestry in the Czech Republic is based on the international framework set out by the first Ministerial Conference on the Protection of Forests in Europe and also in conjunction with the preparation of the Czech Republic for accession to the European Union. National and regional forest...
Management strategies on territories with special status of protection in the Czech Republic
J. Simon
J. For. Sci., 2004, 50(11):510-513 | DOI: 10.17221/4648-JFS
About 15% of the area of the Czech Republic is classified as territories with special status of protection, most of which is covered with forests. At present, at the time of integration of the country into the European structures, an increase in the area of such territories by approximately 20% is expected. The territories show significant variation of protection objectives, management restrictions, profound differentiation in natural conditions, structure of ownership and different levels of damage, especially that caused by anthropogenic pressure. This situation requires the formulation of long-term management strategies. The problem can be solved...
Development of forest stands condition and its monitoring in the Czech Republic
P. Fabiánek, V. Henžlík, K. Vančura
J. For. Sci., 2004, 50(11):514-519 | DOI: 10.17221/4649-JFS
In 1986, the UN ECE established the International Cooperative Programme on Assessment and Monitoring of Air Pollution Effects on Forests (hereinafter ICP Forests) to respond on the growing concern about forest damage caused since the beginning of eighties by air pollution load. Pan-European grid of the (ICP Forests) monitoring plots represents one of the most important systems of forest ecosystems assessing and checking. The Czech Republic is unfortunately well known due to this problem and so the country joined ICP Forest Programme since the very beginning. The paper presents general information on Czech forest stand condition that gained...
A new concept in sustainable forest management - the need for forest ecosystem and landscape research
J. Kulhavý
J. For. Sci., 2004, 50(11):520-525 | DOI: 10.17221/4650-JFS
The greatest advance in ecosystem research was made in the last century. The development and acceptance of forest ecology by foresters occurred because it provided a means for recognizing, understanding, classifying and mapping the natural variation of forests. Forest ecology involved studies at the individual, population, community, and ecosystem levels but such studies always needed to involve the ecosystem concept. Today, the new concept of "ecosystem and landscape forestry" integrating ecological and socio-economic research has been developed on the basis of EU COST Action E-25 European Network for a Long-term Forest Ecosystem and Landscape...
Sustainable management of mountain forests in the Czech Republic
S. Vacek, V. Balcar
J. For. Sci., 2004, 50(11):526-532 | DOI: 10.17221/4651-JFS
Forest management in the Czech Republic (CR) was not shaped in the environment of natural forests but in the territory that was influenced by unregulated felling and animal grazing for a long time. Hence the fear for sustainable and balanced benefits from forests endangered by long-term uncontrolled exploitation was legitimate. Almost after three centuries of application of the sustainability principle, forests are considered not only as a source of renewable wood raw material but also as a tool of the environment formation. Mountain forests are an important landscape component of this country. They are an object of specific importance from the aspect...
Different types of damage in mountain forest stands of the Czech Republic
B. Lomský, V. Šrámek
J. For. Sci., 2004, 50(11):533-537 | DOI: 10.17221/4652-JFS
Forests in the Czech Republic are highly influenced by the antropogenous factors - those are particularly air pollution, pollutant deposition, soil degradation, change of the natural forest ecosystems, and also global climate changes. Significant damages due to air pollution are visible already 50 years (the Ore Mts. region). Since 1989 the sulphur emission has decreased significantly. By the end of 90ies SO2 emission was reduced in nearly 90%. In the 1990-1995 period, the change of air pollution situation in mountain regions resulted into the spruce stands condition improvement, and good progress of transitory stands (birch, blue spruce,...
Forestry, mountain catchments and floods in the Czech Republic
M. Bíba, J. Jiřík, K. Vančura
J. For. Sci., 2004, 50(11):538-541 | DOI: 10.17221/4653-JFS
A short introduction of historical overview and current situation refer to forestry problems of the country. Local climate is characterized and impacts of natural phenomena are described, as well as the impacts of human beings. The influence of forest management is mentioned and discussed in relation to latest catastrophic floods. The territory of the Czech Republic is damaged especially by a high intensity of atmospheric precipitation abnormal values which lead to a local or regional damage. In the catchment areas of torrents, damage leads to faster soil erosion, development of ravines, landslides, moving of soil sediments and their deposition, devastation...
Biologically degradable oils at working with power saws
A. Skoupý
J. For. Sci., 2004, 50(11):542-547 | DOI: 10.17221/4654-JFS
Power saws require a relatively large amount of oil for their operation the reason being idle lubrication of the cutting chain. Oil leakages in the environment can result in soil and water contamination and are known to impact both flora and fauna. Many countries in Europe struggle to minimize the damage by imposing the use of biologically degradable oils for these purposes. The work presents an assessment of these biologically degradable oils from the viewpoint of their possible occurrence in environment and from the viewpoint of their technical characteristics which affect reliability and economy of working with power saws. Oil dispersion is evaluated...
