Unfortunately it has suffered from serious dieback in Central Europe in the last decades. Reintroduction of Silver fir is not an easy task as seedlings and saplings are sensitive to many environmental harmful factors and to game browsing damage especially in early stages after germination. The fertilization of Silver fir saplings could help shorten the sensitive period of the tree species. Silver fir research plots were founded in 1999 to observe an impact of different fertilizers on its height growth. Applications of conventional as well as modern fertilizers confirmed the positive influence on the height growth of the species. Apical dominance ratio was used to evaluate the growth status of saplings.

The investigated objects were three research plots of beech in the growing phase of maturing stand in Central Slovakia subjected to different air pollution stress. Larger negative changes in the beech necrotic disease were recorded on a plot situated in the close vicinity (1.5 km) of the aluminium plant. We consider the permanent negative influence of pollutants from the aluminium plant on the vitality of trees as the main cause of the negative changes. The health state of beech (defoliation) on this research plot was also permanently significantly worse than on the two other plots situated at a larger distance from the pollutant source (7 and 18 km respectively). The state of necrotic disease on the plot situated at the distance of 7 km was significantly better in 2004 than in 1995. This difference could result from the age of beech trees being lower by 15 years than on the plot distant 18 km from the pollutant source where the state of necrotic disease has not changed. On none of the studied plots was the tree defoliation influenced by the current state of the necrotic disease of beech stems.

Kaliszewski Title: The policy process on climate change Abstract: The United Nations Framework Convention on Climate Change accepted in 1992 at the Earth Summit in Rio de Janeiro provides principles and framework for cooperative international action on mitigating climate change. But it soon became clear that more radical targets were needed to encourage particular countries to reduce greenhouse gas emissions. In response, countries that have ratified the United Nation Framework Convention on Climate Change accepted the Kyoto Protocol in 1997. The rulebook for how the Kyoto Protocol will be implemented - the Marrakech Accord, was agreed in 2001. This paper describes political instruments and facilities of mitigating climate change by forestry proposed in those political documents.

Forest roads are the basis of permanent access. The paper presents the results of research and knowledge of making access to mountain forests in a model territory of LHC Ďumbier in the Low Tatra Mts. We describe an ecologically suitable model of making access based on making access by permanent skidding roads constructed at an optimal spacing, which are proposed to be interconnected by cable systems for timber transportation or on slopes with gradient over 70% with the use of helicopters for timber transportation. Principles of making access to mountain forests are also presented that are worked out for the field of preparation and projection intentions of further access, proposals and projection, implementation and maintenance of constructed communications and special facilities which will secure optimal access, minimal damage and maximal benefits in the given area.

The Forests of the Czech Republic, state enterprise, was charged with management and supervision, hence economic activities of the subject are provided on the basis of contracts by entrepreneurial units called contractors in the forestry. The purpose of the paper is economic analysis of the Forests of the Czech Republic, state enterprise, in the period 1998-2002. The objective is the construction and testing of an elementary method of financial analysis as well as outline of financial situation and development of the chosen subject generally. The paper contributes to branch economy analysis, common in agriculture and wood-processing industry.
