The influence of forest management on occurence of microhabitats that are important for forest biodiversity
Heřmánková, Valentýna ; Hofmeister, Jan (advisor) ; Kozák, Daniel (referee)
A large part of the declining forest biodiversity (saproxylic insects, birds, fungi, bryophytes, lichens etc.) is linked to microhabitats that occur on structures typical of old-growth forests and are relatively rare in managed forests. In recent decades, alternative, more close-to- nature management practices have been slowly gaining ground, but their impact on microhabitats, and thus their potential value for forest biodiversity, has not yet been assessed. Therefore, I made a comparison of the occurrence and quality of microhabitats in 4 forest plots (8,3 to 42,5 ha) representing different forest management methods (traditional clearcutting management, alternative selective management and forest reservation at the time of data collection 65 years without intervention) in the natural conditions of the Central Bohemia. In the plots, using the adopted methodologies, I conducted an inventory of the presence of microhabitats on living trees and an inventory of deadwood and their assessment. The highest abundance and quality of microhabitats and deadwood were in the nature reserve, which at the same time completely exhausted the gamma diversity of all plots studied. The occurrence of microhabitats in clearcut and selective management forests was comparable and mostly low. The positive factors...

The study of the recreational use of El Bierzo (Spain)
Fernandez Arias, Pablo
The main idea of this study is to develop various industries that have this area as well as having a vision of global set both politically Bierzo, economically and socially, in order to implant companies in different sectors later cited with an environmental and landscaping protecion for improvement and enjoyment of all residents and visitors to this area and to protect the different ecosystems, vegetation and wildlife threatened by various industries that can destroy large areas of natural interest. All this is justified by the need to advance a direcion to protect the environment and allow a rural development according to environmental protecion implemented by the various European, Spanish and regional policies for their impact as small as possible. At first discussed in which the climate, geology, hydrology of the area, also the historical-social answer was analyzed and an analysis of the forestry sector, finally has developed an inventory of vegetation and wildlife analyzed It exists in this region. The purpose of this analysis and inventory has been developing and publishing the different conclusions and results that can be read later.
