Dendroflora parku w Zawieprzycach liczy 26 taksonów (2010 r.). Zinwentaryzowano 381 drzew. Na obszarze parku dominują gatunki związane ze zbiorowiskami żyznych lasów liściastych. Najliczniej występują: Tilia cordata Mill., Fraxinus excelsior L., Acer pseudoplatanus L. i Carpinus betulus L. Na podstawie inwentaryzacji przeprowadzonej w 2010 r. do ochrony pomnikowej wytypowano 6 egzemplarzy. Park jest...
Field research on the ruderal flora of fifteen abandoned villages in Kampinos National Park revealed that among the 550 vascular plant species identified, 13% represent the oldest flora settlers, or archeophytes. The number of archeophytes in particular villages varied from 28 to 46. Only 8 species were present in all of the villages: Armoracia rusticana, Ballota nigra, Capsella bursa-pastoris, Descurainia...
The vascular flora of the Szczawin forest complex was studied from 2007 to 2011. The results were compared to those of a previous study carried out from 1971 to 1976. The Szczawin forest complex is located north-east of Zgierz in central Poland. It contains the Grądy nad Moszczenicą nature reserve, which was established to preserve the oak-hornbeam forests with their rare protected plant species....
The paper presents results of floristic research on vascular plants in the abandoned limestone quarry in Tyniec. Altogether, 104 species representing 26 families were found. The species composition of the plant communities in the quarry was characteristic of dry grassland and meadow communities. The degree of synanthropization was 97.1%. Carlina acaulis was the only protected species found in the...
The aim of the study was to determine the degree of the enrichment of the flora of peat bogs and transition mires in anthropophytes and apophytes. The study included the flora of 87 bogs and mires in the Kashubian Lakeland and Kashubian Coastal Region. 149 species of synanthropic plants were found, most of which were found at a single site. Apophytes represented nearly half of the total number of...
In 2009 and 2010, floristic research was carried at two sites in Wrocław, Poland. The first site was along 3.5 km stretch of the newly built city ring road between Bielany and Oporów. The second site was along a newly built road near the post office in Oporów. The aim of the study was to determine whether spatial and technical urbanization in the area has favored the development of a variety of segetal...
This study is part of a long term, multi-faceted research project on rates and directions of spontaneous vegetation dynamics after cessation of agricultural land use, and on the effects of anthropogenic modifications of this process by managed mowing or plowing. The results are based on data from a permanent plot established in Wielkopolski National Park in 1976. This article presents share spectra...
Floristic and ecological data was collected three times (in 2000, 2006 and 2011) in fifteen urban parks in Wrocław. Results were compared to determine whether bryophytes can survive in urban environments, or whether they die off because of the constant pressure of urbanization. Other questions examined include whether bryophytes remain in the same habitats, or whether they change their spatial distribution;...
Various types of artificial habitats are associated with the modified landscapes. Among them are abandoned sand and gravel pits. These sites have a varied terrain. The presence of slopes, elevations, depressions and ponds creates favorable conditions for the colonization and development of species from very different habitats. Exploitation of raw materials and the accompanying infrastructure lead...
The aim of the study was to conduct an environmental evaluation of 6 selected sections of the improved Mietiułka River, which included an inventory and analysis of the vascular flora associated directly with this watercourse. The results of the study have shown that the flora of the study area is diverse in taxonomic, syntaxonomic and ecological terms, and that it comprises both typical aquatic plants...
The relief of the Zadroże Dune was described, as well as the comparison was done on its vegetation cover and the flora in its two phases of the development, i.e. before the afforestation of the dune and approximately 60 years after reconstruction of the forest. The first state was described in the paper dated 1949. During that period the dune constituted the first common study area for the research...
The floral and phytosociological research conducted between 1998-2001 in the area of the artillery range shows that there are 460 different species, including 363 vascular plants and 96 algae, bryophytes and lichens. The aforementioned count includes 45 taxa that are fully or partially protected. In the investigated area there are 30 species of vascular plants and 13 lichen species endangered to a...
The paper contains a list of 39 liverwort species collected on decaying wood (logs, stumps and snags) and on tree-fall disturbances (root plates, pits and mounds) in forest communities in the Karkonosze. Three of these species are threatened in Poland: Cephalozia catenulata, C. leucantha, Marsupella emarginata and three are partially protected by law: Cephalozia catenulata, Bazzania trilobata i Ptilidium...
The area of urban green space is rather small in the majority of Polish cities. Considering the combination of an important biocenotic function with recreational purposes, there is an urgent need of determining the balanced conditions, which could ensure the high species diversity in a continuous anthropization. Pilczycki Park, despite of its location in the central part of Wrocław, is characterized...
