Acidophilous oak forests of the Wielkopolska region (West Poland) against the background of Central Europe

Abstract

Acidophilous oak forests of the Wielkopolska region (West Poland) against the background of Central EuropeThis monograph gives the phytosociological characteristics of acidophilous oak forests from the classQuercetea robori-petraeae(Aulacomnio androgyni-Quercetum, Molinio caeruleae-Quercetum, andCalamagrostio arundinaceae-Quercetum) and the closely related forest communities from the classesQuerco-Fagetea(Potentillo albae-Quercetumand acidophilous forms ofGalio sylvatici-Carpinetum) andVaccinio-Piceetea(Querco roboris-PinetumandSerratulo-Pinetum) in the Wielkopolska region and adjacent areas. The report is based on 1655 relevés selected from 59 published or unpublished studies. The analysed and revised syntaxa are described in accordance with the International Code of Phytosociological Nomenclature. The distribution of the documented localities of all associations and subassociations in the study area is shown in cartograms on the ATPOL grid (squares of 10 km x 10 km). The classical phytosociological methods are complemented with multivariate ordination methods (detrended correspondence analysis and/or principal component analysis) and analyses taking into account Ellenberg indicator values. The natural geographical and site differentiation of all the plant associations is presented, and stages of degeneration are distinguished in some of them. The separation of degenerated forms and substitute forest communities has allowed a clearer classification of the studied syntaxa. This study shows that the analysed associations can be subdivided into 16 subassociations and 23 variants. For 5 subassociations, nomenclatural types are designated here. The most common association in the study area isCalamagrostio arundinaceae-Quercetum, but most of its relevés represent various stages of degeneration. Among communities from the orderQuercetalia roboris, patches ofAulacomnio androgyni-QuercetumandMolinio caeruleae-Quercetumare rare. On the basis of this detailed study, a coherent system of classification of acidophilous oak forests from the orderQuercetalia roborisin Central Europe is proposed. The results are important for biodiversity conservation and sustainable forest management.

Vegetation diversity of the Scots pine stands in different forest sites in the Turawa Forest District

“…Some patches occurring on these sites represents Leucobryo-Pinetum association, which in the case of these sites is secondary community for Calamagrostio arundinaceae-Quercetum petraeae or for Querco roboris-Pinetum, which can constitute potential vegetation of BMśw (Sikorska, Lasota 2007;Danielewicz et al 2013). In the case of patches identified as Leucobryo-Pinetum, these would probably be typicum sub-associations for Calamagrostio-Quercetum and Querco roboris-Pinetum (Kasprowicz 2010). However, most of patches on BMśw were identified as the community of Pinus sylvestris and Molinia caerulea.…”

“…This does not exclude the above-mentioned associations (Calamagrostio arundinaceae-Quercetum petraeae and Querco roboris-Pinetum) as potential vegetation. In this case, more probable would be moist sub-associations: Calamagrostio arundinaceae-Quercetum petraeae molinietosum and Querco roboris Pinetum molinietosum (Kasprowicz 2010). However, Molinio caerulae-Quercetum roboris cannot be excluded, although it is assigned to BMw or LMw (Sikorska, Lasota 2007;Danielewicz et al 2013).…”

Phytosociological study of the forest vegetation of Kyiv urban area (Ukraine)

“…The closest alliance might be the Pino-Quercion (currently recognized as a synonym of the Dicrano-Pinion alliance (Mucina et al 2016)) and the closest association is Querco roboris-Pinetum that is often reported from Ukraine (Onyshchenko 2006, Solomakha 2008, Panchenko 2013. But syntaxonomic entity of Querco-Pinetum association is controversial, and some Polish authors suggest that it is close or even based on the type of the former association Pino-Quercetum Kozłowska 1925(Ławrynowicz et al 2004, Kasprowicz 2010. Table 8 syntheses the floristic differences of syntaxa of acidophilous pine-oak forests according to published materials.…”

Ellenberg’s indicator values for soil nitrogen concentration and pH in selected swamp forests in the Central Black Sea region of Turkey

“…The mean EIVs were calculated as weighted averages of the species indices based on the cover-abundance of species for each particular plot and they were calculated by using arithmetic means for all species (Obidziński, 2004;Kasprowicz, 2010). EIVs for the swamp forest species studied were calculated by weighted average formula:…”
