Opis:
The range of acidophilous oak forest from Quercetea robori-petraeae Br-Bl. et Tx. ex Oberd. 1957 in Central Europe depends largely on the syntaxonomical concept used and is still provisional. The most continental association from this class occurring in Poland is Calamagrostio arundinaceae-Quercetum petraeae Hartm. 1934 Scam. et Pass. 1959. It is present in western and central Poland, but its eastern boundary is not well known. The aims of the study were to survey and document new patches of Calamagrostio-Quercetum in central Poland, to check the internal variation of the association and to summary the known distribution of it in lowlands of central-western and central Poland. 23 phytosociological relevés were made within new stands together with soil sampling. New relevé data was subjected to the numerical Wards classification together with acidophilous oak forests datasets from western Poland and oak-pine forests ones from eastern part of the Country. The new dataset was similar to Calamagrostio-Quercetum. Three subassociations were distinguished. Soil parameters and oak site index did not differ from acidophilous oak forest stands from other parts of Poland. The provisional range of Calamagrostio-Quercetum in central Poland was proposed to be moved by circa 60–90 km to the north-east (approximately as far as the Vistula river line) in order to include south-western part of Mazowsze.

Opis:
This paper presents results on the restoration of Scots pine stands established on post-agricultural lands undergoing conversion into mixed stands. Sessile oak (Quercus petraea), common beech (Fagus sylvatica) and small-leaved lime (Tilia cordata) seedlings were planted in artificially created gaps (0,02 ha to 0,05 ha each) cut in six experimental plots (Forest Districts: Bielsk, Krynki, Sobibór, Dobieszyn, Skrwilno and Łupawa) located in 20–25-years-old pine stands. The experimental plots were spread across northern, central and eastern Poland and affected by root-rot fungus (Heterobasidion annosum). Nine years after planting, the number of individual trees and shrub species, their height sum and average height were calculated for fenced artificial gaps (LSO) as well as non-fenced artificial gaps (LSN) and compared to natural gaps (LN) and non-disturbed neighboring stands (D). Results were calculated separately for the planted species (oak, lime and beech) but combined for all other species. The results indicate satisfactory restoration in all of the investigated plots except in Krynki, which is located in a relatively poor site. Significant differences appeared between height sum as well as average height of planted species in fenced compared to non-fenced gaps. Furthermore, in both, natural and artificial gaps, the species composition of the young generation was enriched with natural regeneration of pioneer species, mainly silver birch (Betula pendula), rowan (Sorbus aucuparia) and aspen (Populus tremula).
