Opis:
The phytosociological database Polish Vegetation Database collects relevés of all vegetation types in Poland. The database was established in 2007 and is located at Department of Biodiversity and Plant Cover Protection, University of Wrocław (http://synbiot.uni.wroc.pl). On March 2012, the database included 40000 relevés collected between 1927 and 2011. Most of relevés was taken from published papers and represents almost all types of habitats of Poland. Large groups of relevés represent meadows and pastures (Molinio-Arrhnehteretrea), broadleaf forests (Querco-Fagetea), arable land communities (Stellarietea), coniferous forests (Vaccinio-Piceetea) and eutrophic reed communities (Phragmitetea). In comparison to other countries in Central Europe, Polish Vegetation Database currently belongs to medium-sized databases, with full functionality and accessibility. The present article describes its development, basic operational information and how it can be used in analysis of vegetation in Poland.

Opis:
The paper contains results of investigations carried out in crop fields within the protected area, which is an important refuge of species diversity in grounds dominated by large-area farms. The segetal vegetation is represented by 13 plant communities, the development of which is influenced by various tillage manipulations. As a result, the segetal flora of the Ślęża Landscape Park is heavily threatened and the structure and species richness of phytocoenoses are distinctly transformed. This is reflected in the frequency of weed occurrence in crops (i.e. there is a small group of common species and a very numerous group of species with 1 or 2 localities), as well as in values of biocoenotic indicators, e.g. the values of diversity indicator H vary between 1 and 3.5. An analysis of archaeophytes participation (frequency and numbers) in ATPOL squares indicates their significant connection with archaeological sites of the Neolithic settlement. Particular adherence to the early Neolithic settlement areas shows a group of species from the Caucalidion alliance. The richness and diversity of the Park vegetation, conditioned by many hundreds of years of agriculture, are now strongly transformed and have become impoverished. Establishing the Landscape Park, in order to preserve the natural-landscape character of the environment and its cultural and historical values, does not ensure the protection of both the species and the phytocoenotic diversity of this area.

Opis:
The goal of this study was to propose a hierarchically nested classification system comprising four principal levels of the Braun-Blanquet system for Polish grasslands of the class Molinio-Arrhenatheretea. Using the Cocktail method, we defined consistent criteria for delimitation of the class, three orders, nine alliances, and 45 associations. Formal definitions were prepared using the summed cover and presence/absence information of species groups and individual dominant species. We created an expert system with a set of assignment rules that unambiguously classify relevés to a single unit at the given abstraction level of the Braun-Blanquet system in such a way that a relevé matched by the definition of a focal vegetation unit must be matched by definitions of all superior units. Of 11,535 relevés classified to Molinio-Arrhenatheretea, 36% were recognized at the association level, and 57% and 85% at the alliance and order level, respectively. All relevés were assigned unambiguously, meaning that a single relevé could not be assigned to more than one unit within the same hierarchical level (no overlap between vegetation units). This study is the first proposal of a hierarchically nested classification system that classifies grassland vegetation at different syntaxonomical levels unequivocally. It is important to create definitions for different syntaxonomical levels because the majority of vegetation patches do not fit to the associations, but can only be assigned to high-rank units such as alliance, order, or class.

Opis:
The species richness and structure of Spergulo-Chrysanthemetum segeti have been assessed on the basis of 25 phytosociological relevés made by the Braun-Blanquet method in the Drawsko Lakeland (Poland). Two variants have been distinguished, Spergulo-Chrysanthemetum segeti chamomilletosum typicum and Spergulo-Chrysanthemetum segeti chamomilletosum with Plantago intermedia. The paper presents the distribution and analytical characteristics of this subatlantic association against the background of habitat conditions.
Celem pracy było rozpoznanie oraz ekologiczno-fitosocjologiczna charakterystyka Spergulo- -Chrysanthemetum segeti na Pojezierzu Drawskim, ze szczególnym uwzględnieniem jego zróżnicowania na tle warunków siedliskowych. Podano ważniejsze cechy florystyczne wyróżnionej agrofitocenozy, jej wewnętrzne zróżnicowanie i powiązania z warunkami siedliskowymi. Do oceny niektórych z nich oznaczono pH w H2O i 1 M KCl metodą potencjometryczną. W obrębie Spergulo-Chrysanthemetum segeti chamomilletosum wyróżniono dwa warianty: typowy i z Plantago intermedia. Płaty wariantu typowego wykształcają się na glebach brunatnych właściwych i wyługowanych o odczynie słabo kwaśnym wytworzonych z piasków gliniastych i glin. Płaty wariantu z Plantago intermedia rozwijają się na czarnych ziemiach właściwych i zdegradowanych, rzadziej na madach i glebach murszowych. Wariant typowy podzespołu występuje najczęściej na glebach kompleksu żytniego bardzo dobrego (4), pszennego dobrego (2) i pszennego wadliwego (3), natomiast wariant z Plantago intermedia i subwariant z Galeopsis speciosa – na glebach kompleksów zbożowo-pastewnych – mocnego (8) i słabego (9). Cechą charakterystyczną opisanego syntaksonu jest znaczny udział gatunków z rodzaju Galeopsis, którym towarzyszą Anchusa arvensis i Lapsana communis. Częste występowanie tych taksonów upodabnia omawiane zbiorowiska do agrofitocenoz występujących na obszarach wysoczyznowych, pogórzu i w górach.

Opis:
The influence that different sampling methods have on the results and the interpretation of vegetation analysis has been much debated, but little is yet known about how the spatial arrangement of samples affect patterns of species composition and environment–vegetation relationships within the same vegetation type. We compared three data sets of the same sample size obtained by three standard sampling methods: preferential, random, and systematic. These different sampling methods were applied to a study area comprising of 36 ha of intermittently wet Molinia meadows. We compared the performance of the three methods under two management categories: managed (extensively mown) and unmanaged (abandoned for 10 years). A total of 285 vegetation-plots were sampled, with 95 plots recorded per sampling method. In preferential sampling, we sampled only patches of vegetation with an abundance of indicator species of the habitat type, while random and systematic plots were positioned independently from the researcher by using GIS. The effect of each sampling method on the patterns of species composition and species–environment relationships was explored by redundancy analysis and the significance of effects was tested by the randomization test. Preferential sampling revealed different patterns of species composition than random and systematic sampling methods. Random and systematic sampling methods have resulted in broader vegetation variability than with preferential sampling method. Preferential sampling revealed different relationship between soil parameters and species composition in contrast to random and systematic sampling methods. Although we have not found significant differences in vegetation–environment relationships between random and systematic sampling methods, random sampling revealed a more robust correlation of species data to soil factors than preferential and systematic sampling methods. Intentional restriction of vegetation variation sampled preferentially may be detrimental to statistical inference in studies of species composition patterns and vegetation–environment relationships.
