The assessment of environmental and anthropogenic factors impact on plant communities variation was made, on the example of park in Bukowiec. Geobotanical methods used for vegetation elements inventory bring data about vegetation structure, species composition, but also vegetation dynamics. This data can enrich traditional inventories of historical landscape parks.

The aim of this study is to specify which plant species, included in the ancient forests plant species list, can indicate old woodlands in parks and what plant features are characteristic for certain habitat types. Richest in ancient forest plant species are those fragments of woodlands, which have existed continuously for at least 120 years, and their fragments suffered least from human pressure during that time, whereas recent woodlands are characterized by a small share of ancient forest indicator species and domination of nitrophilous species. Investigated plants usually propagate vegetatively, their seeds are of a small size and they have regularly, densely set leaves. Plants associated with ancient woodlands are good indicators of woodland continuity in parks so they can be used for age assessment in these areas. Accumulation of such ...

Tym razem jest to ujęcie nieco odmienne od opracowań poprzednich zjazdów, gdyż nie koncentruje się na pojedynczym regionie, ale na strefie przejścia między Europą Środkową i Północno-Wschodnią, a ujmując rzecz szerzej – między Zachodem i Wschodem Europy. Opracowanie prezentuje obiekty, leżące na Mazowszu, Polesiu, Podlasiu i Pojezierzu Litewskim. Ich położenie przy granicy wielkich jednostek geobotanicznych skutkuje różnorodnością flory i roślinności. Monografia, chociaż z racji ograniczonej objętości nie przedstawia wszystkich cennych obiektów przyrodniczych między Wisłą a Niemnem, to reprezentatywnie oddaje charakter i zmienność szaty roślinnej na tym obszarze. Dobór prezentowanych obiektów wynika z ich unikalnych walorów przyrodniczych, a jednocześnie z poznawczych upodobań autorów.

Such areas, later excluded from conventional forest management, are now in the process of regeneration. This process takes place in "Las Kabacki" reserve. In order to examine the regeneration of the degraded vegetation of lime-oak-hornbeam forests under the pine canopy and to assess habitat factors affecting the changes, 25 vegetation relevés have been performed twice in the same sites in the years 1979 and 2006. The study showed that the regeneration process generally fluctuates toward more alkaline and species rich forms of syntaxa from the class Querco-Fagetea.

The phenomenon of biotic homogenisation is typical in urban landscapes, but it can proceed differently depending on the scale, a detail that has not been observed in previous studies. This research was carried out in seven Warsaw parks (both public and restricted access). Thirty-four forested areas were randomly selected, some subjected to strong visitors' pressure and some within restricted access areas, free of such impacts. The latter category included woodlands growing in old forest and secondary habitats. Public access to the study areas contributed to the disappearance of some forest species and their replacement by cosmopolitan non-forest species, leading to loss of floristic biodiversity in areas of high ecological importance at the city scale. Some human-induced factors, including soil compaction and changes in soil pH, moisture and capillary volume, were found to cause habitat changes that favoured native non-forest plants. Despite changes in species composition, the taxonomic similarity of understorey vegetation in both categories--public access and restricted access--was comparable. In a distance gradient of measurements taken around selected individual trees, there was found to be significant variation (in light, soil pH and compaction) affecting the quality and quantity of understorey vegetation (including rare species). In conclusion, the protection of rare forest species could be achieved by limiting access to forested areas, particularly in old forest fragments, and we highly recommend its consideration in the proposal of future park restoration plans.

The ‘Mierzwice ’ nature reserve (forest district 206b, c and d of the Sarnaki Forest Inspectorate), situated in the area of the Podlaski Przełom Bug Landscape Park, is one of the most valuable natural assets of the central Bug river valley. The 12.98 ha reserve was established in 2010 to aid protection of the stand of xerothermic vegetation and its surrounding deciduous forest. In total, eight plant

Many authors when evaluating fo-rests, distinguish separate class of forests, existing for a long time. For valuable forest assessment in whole Europe "ancient woodland" concept is widely applied, which is based on calculations in whole fl ora of indicator species abundance. There are separate lists of indicator species in different countries e.g. in Sweden, Germany, Belgium, Netherlands, Poland, Great Britain, though they are similar, connected with woodlands, whose habitat continuity dates back for 250 years and more. If the method is related to the concept initi-ated in Poland in the beginning of 20th century about attachment of species to separate phases of a tree stand development, for applying the method it should be taken into account how the indicator species behave in habitat of undisturbed conti-nuity in a tree stand of different age and how that affects thei...
