Juniper pastures in the Wallachia area and predictors of their preservation
Mizera, Ondřej ; Křenová, Zdeňka (advisor) ; Mudrák, Ondřej (referee)
Common juniper (Juniperus communis), as a species of predominantly open habitats, used to be part of semi-natural grassland communities, such a pastures. In the area of Moravian Wallachia (eastern part of the Czech Republic) this type of grassland is known as juniper pasture, however as in the whole of Europe, it is a type of habitat that is disappearing rapidly from the landscape, among other reasons due to the absence of juveniles in the population. A total of 20 potentially preserved juniper pastures were identified within nine cadastral areas in the Moravian Wallachia (Beskydy Protected Landscape Area) and visited during the vegetation period. The total number of J. communis individuals was recorded, including their dendrometric (crown height and radius) and descriptive characteristics (sex, vitality, developmental stage, sociability, form). Characteristics of vegetation cover and type of site management were also recorded to define the main factors influencing the vitality and proportion of juvenile individuals in the population of J. communis. Field research was supplemented by analyses of orthophotos and topographical data processed in a GIS environment. In total 2,896 juniper were recorded at 20 locations, while the population of J. communis in the area of interest can be characterized by...

Comparison and evaluation explantates plantings of juniper (Juniperus communis), originally from PR Mšály (1981-1985)
BUBLÍK, Martin
Common juniper (Juniperus communis) is a tree or a shrub. This species is original in the Czech Republic which was very widespread in the landscape. It is from the lowland to the mountain range, which means that it is completely unmistakable for the soil species. It is classified as a critically endangered species in the Czech Republic, due to changes in landscape management. The aim of this work was mapping and surveying the situation on the mentioned localities, where the research was carried out in 2004-2005 and in 2015. At the Na Mšálech locality there were found 135 individuals. Based on the data found, the overall health condition was greatly aggravated by the populations under study, specifically at the Paris site.

Population juniper (\kur{Juniperus communis}) in the selected area
KOUPAL, Vít
The paper maps the community of Common Juniper (Juniperus Communis) encountered at Konrac, a site included in the Česká Kanada Nature Preserve. The site itself, or rather the common juniper growing there, does not have the benefit of special legal protection; consequently, no targeted steps have been taken to maintain the juniper community intact in the Konrac landscape - still, the site allowed to monitor the natural development of the community in conditions typical of the current methods of farming. The locality is described to encompass four main types of habitats: stony islands amid meadows; unplowed strips of land around former small fields; peripheries of open stands; and peripheries of close stands. The acquired (and subsequently processed) data point to the conclusion that the habitat at the unplowed margins of fields suits the common juniper communities quite well, even without any human intervention in the farming practices beyond what is implemented on the site now.

Population of juniper (Juniperus communis) on dikes Třeboň ponds
PELÁN, Rudolf
Common Juniper (Juniperus communis) is a low-growing shrub or small tree, which is autochthonic and previousely widely distributed in the Czech Republic. Common Juniper occurrence is associated with sandy, drying and waterlogged soils from lowlands to mountains. It is retreating species from the middle of last century because of changes in landscape and agriculture. Now, it is endangered species of flora of the Czech Republic. The aim of this work was to map the population on selected areas of Třeboňsko focusing on the pond dikes and comparing with others. Next, there was dendrometry (forest mensuration), detection of individual specimens with using GPS and creating maps with location of Junipers. 190 specimens were founded on selected area, most of them were founded in forests and near ponds.

The population of juniper (\kur{Juniperus communis}) in the selected area of the Pilsen Region
KELÍŠEK, Michal
Juniperus communis is a shrub or rather a small tree, original and widely-spread formerly in the Czech Republic. Nowadays it belongs to the endangered species. Its galbulas, called juniper berries, are used as spice or for production of alcoholic beverages. The aim of this work was to map the population of juniperus communis in the selected area of Pilsen region ? VKP Jalovcová stráň Odolenov, further to perform dendrological measurements and draw up maps. In the locality mentioned above the population of 253 pieces of original junipers and 260 pieces of seedlings, planted in 2010 ? 2011, was found out. Average height of 290 cms and a trunk circumference of 23 cms at original junipers (40 ? 50 years old) were found out.

Juniperus communis ocurrence in South part of Protected Area Trebonsko
DVOŘÁK, Martin
In this work, I ´ve been monitoring occurrence of Juniperus communis in south part of {\clqq}CHKO Třeboňsko``, which is protected area. At first I´ve been studying literature specialized in focusing on problems of occurence Juniperus communis in the world and in this concrete area. Than I was systematically creating a net of all the exemplars in proper area, I ´ve been noting their characteristics and taking a photos. I was statistically analyzing the data and compare with other works, which are engaged in this issue.
