Relevance of the problem. Common juniper (Juniperus communis L.) is a characteristic underbrush plant of the dry and infertile forest ecosystems. Under favorable conditions, mostly on exposed slopes, common juniper comprises unique juniper communities. The species occupies a large range, is characterized by ecological plasticity and a large variety of populations (Adams, 2008). In many areas of the range it is an important element of the ecosystem, characterized by a large variety of forms. However, the prevalence of junipers and their ecological importance is often dealt with episodically, and on a wider scale - only in the British Isles (Plantlife, 2007, Thomas, 2007) and in some regions of Russia (Барзут, 2007; Михеева, 2002). Despite the large range, common juniper remains one of the least explored coniferous species. According to the Lithuanian National forest inventory data, common juniper is the most widespread in the south-southeastern Lithuanian pine forests on infertile (Nb) forest sites of normal humidity. Nb site occupies more than one fifth of the Lithuanian forest area, while about 94% of stands on this site type occupy pine stands where common juniper is the most common plant in the underbrush (State Forest Service, 2009). Juniper communities formed in the underbrush under intense forest management conditions generally suffer from economic activity, particularly due to final forest felling, when the largest and most valuable individuals are often damaged or...

Esant palankioms sąlygoms dažniausiai atviruo-se šlaituose paprastasis kadagys sudaro unikalias kadagynų bendrijas. Rūšis užima didelį arealą, pasižymi ekologiniu plastiškumu ir didele populiacijų įvairove (Adams, 2008). Daugelyje arealo sričių jis yra svarbus ekosistemos elementas, kuriam būdinga formų įvai-rovė. Tačiau kadagių paplitimas bei jų ekologinė svarba dažniausiai nagrinėjami epizodiš-kai, o plačiau – tik Britų salose (Plantlife, 2007; Thomas, 2007) ir kai kuriuose Rusijos re-gionuose (Барзут, 2007; Михеева, 2002). Nors arealas ir didelis, paprastasis kadagys vis dar yra viena iš mažiausiai ištirtų spygliuočių rūšių. Remiantis Lietuvos Nacionalinės miškų inventorizacijos duomenimis, paprastasis kadagys yra labiausiai paplitęs Pietų-Pietryčių Lietuvos pušynuose normalaus drėgnumo nederlingose (Nb) miško augavietėse. Nb augavietė užima daugiau nei penktadalį Lietuvos miškų ploto, o apie 94 % šios augavietės medynų sudaro pušynai, kuriuose paprastasis ka-dagys yra dažnai aptinkamas trako augalas (Valstybinė miškų tarnyba, 2009). Intensyvaus miškų ūkio sąlygomis medynų trake susiformavusios kadagių bendrijos paprastai nukenčia nuo ūkinės veiklos, ypač nuo pagrindinių miško kirtimų. Jų metu dažnai pažeidžiami arba sunaikinami vertingi stambiausi kadagių individai. Be to, pasikeičia šviesos ir temperatū-ros sąlygos bei hidrologinis režimas, todėl... [toliau žr. visą tekstą]

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.

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.

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.
