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 (\kur{Juniperus communis}) on Mšály (BR Třeboňsko)
KELÍŠEK, Michal
Common juniper (Juniperus communis subs. Communis) is a shrub or a tree original in Czech Republic which was widespread there in the past. It grows either in lowlands or in mountains and it is undemanding to the soil. Nowadays, there is a lower number of it because of economic transformation in landscape. In consequence of this, it is on the list of endangered species of Czech Republic. The aim of this project was to chart the current state of population of common juniper in region "Mšály" (in The Protected Landscape Area of Třeboňsko). 144 living specimens were founded there. Dendrometry, mensuration of the specimens by GPS and drawing the new maps was realised. Another aim was comparison of the new data with the results of the research in 2004 2007. It was ascertained, that the observed population has a decreasing tendency in it's quantity. The average height of a specimen in the population has grew from 0,8 m to 4,9 m since 2007.

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.
