Retrospective investigation of defoliation and regenerative processes in the assimilation organs as a basis for estimation of long-term multiple stress impact of mountain Norway spruce forest stands
Cudlín, Pavel ; Moravec, Ivo ; Havlíček, František
Retrospective method of determination of the response of Norway spruce forest stands to multiple stress was applied for four permanent research plots in the Jizera Mts. Stress exceeding (lost of more than 50% of primary shots) has been observed on all plots, however, no signifacant damage to trees (lost of more than 80% of primary shots) have been observed. It results in sufficient tree regeneration potential of investigated forest stands.
Central-European mountain spruce forests: regeneration of tree species after a bark beetle outbreak
Jonášová, Magda
Two different approaches were applied to mountain spruce (Picea abies) forests attacked by bark beetle in the Šumava National Park (Czech Republic): (1) a small portion of the stands was left without intervention, relying upon natural regeneration, and (2) traditional technical measures were adopted, in which attacked trees were felled and removed. The results confirmed that the original tree species of the mountain spruce forests regenerate well under dead canopy and the bark beetle outbreak could even be considered as a tool for the restoration of their natural character.

Searching for lost times - review of the study (1983): \"Landscape-ecological consequences of the constraction and running the Nuclear power plant Temelín\"
Bartoš, Michael ; Kušová, Drahomíra ; Těšitel, Jan
A part of the study from the year 1983 'Landscape-ecological consequences of the construction and running the Nuclear power plant Temelín' was used as one of the information bases for the research project 'Social-ecological and psychological impacts of the nuclear power plant of Temelínö. The main hypothesis of the study was that nuclear power plant Temelín would be the main driving force of the regionŽs development. From nowadays point of view this hypothesis is actual (was accomplished). On the other hand the study didnŽt take into account the possibilities of political and economic changes in the Czech Republic. As a result, many of socio economic phenomena forecasted by the study have not become reality.
Perception of the nuclear power plant of Temelín by local population in two time horizons (1993/2003)
Těšitel, Jan ; Kušová, Drahomíra ; Bartoš, Michael
Nuclear power plant of Temelín is a phenomenon influencing almost all aspects of life of local population. The article is based on comparison of selected results gained within two sociological surveys, one conducted in the year of 1993 and the other in 2003. Relation of local population to the nuclear power plant was one of key issues addressed in both surveys. Perception of the nuclear power plant proved to have changed over time. The shift can be named äfrom danger to anxiety'. The main factor keeping population anxious about nuclear power plant seem to be a fact that the plant is visible from everywhere, representing thus ävisual contamination of environment' of some kind.
Integrated tourism in the Bohemian Forest and its investigation in the European context
Bartoš, Michael ; Kušová, Drahomíra ; Těšitel, Jan
International project titled 'Supporting and promoting integrated tourism in EuropeŽs lagging regions (SPRITE)ö is aimed at comparing conditions to conduct such a type of tourism within six selected European countries ů Czech Republic, Greece, France, Ireland, Spain and United Kingdom. Šumava Mts. region was selected as one of model areas. By this project, tourism is analysed as a multifaceted phenomenon which can be described as interplay among six principal actors involved ů tourists themselves, host community, businesses, resource controllers, institutions and gatekeepers. Presentation of selected results and their comparison in the international scale is a main subject of discussion in this article.
Biomonitoring of the effect of nuclear power energetics on the environment - present state and perspectives
Boháč, Jaroslav
The long-term monitoring of effects of the atomic power plants, especially at the regional level and with irregular extreme events, is difficult despite the complex biological and ecological response. The system of bioindicators is proposed for the monitoring of effects of atomic power plants o biota. Suitable species and biotopes on border of its distribution are recommended as bioindicators predictors for monitoring of climatic change.
The impact of tourism on the landscape in its micro- and macro scale and the evaluation of its stability. Model area: the right and the left shore of Lipno Reservoir
Šrubař, Vladan
The former boarder zone in the area of Lipno Reservoir right shore that existed till 1989 and was aborted in 1990 provides a good occasion to define impacts of tourism on the landscape. This impact defining can be based on the comparison of boht of the shores. The right one as an area where the entrance was forbidden for 40 years was strongly protected.
Beetle assamblages on the monitoring plots of the Boubín massive in the Bohemian Forest and perspectives of long term monitoring of biotopes state
Boháč, Jaroslav ; Matějíček, J.
In 2003 the investigation of beetle fauna by pitfall traping, sifting and individual sampling was carried out in the area of the Boubín Mt. in the Bohemian Forest. During investigation , 98 beetle species were recovered. Forest species prevail in beetle communities (63%),the frequency of ubiquitous species was lower (24%).
