Summary:

This work brings a phytosociological characteristics of meadows located in the Śliwice commune (central part of the Tuchola Pinewood complex). Phyto-coenoses of green lands located there constitute a kind of enclaves between cropped forests and arable lands on infertile, sandy soils. Phytosociologically, they belong mainly to Molinio-Arrhenatheretea, and also to: Phragmitetea, Koel-erio Glaucae-Corynephoretea Canescentis and Scheuzerio-Caricetea. They rep-resent mainly communities characteristic of wet meadows, although their precise classification is difficult because of a high level of flora alteration. Expansion of low-value species, like Holcus lanatus, Antoxanthum odoratum and Deshamsia caespitosa, was observed. Conditions for protection under the 4th Agro-environmental Package (“Protection of endangered bird species and natural habitats”) are fulfilled mainly by rush communities from Filipendulion ulmariae and Calthion palustris alliances.
