Opis:
A few reports are concerned with sime moulds biota of anthropogenic areas. Majority of areas in the Beskid Śląski lower montane forest belt is covered by monoculture of spruce, planted in the nineteenth century. Intensive field studies were carried out during two vegetative seasons of 2006 and 2007 on the thirty hectares area of planted spruce forest. Two hundred forty four specimens were collected – single sporangium and its groups. In the early spring in 2006 and 2007 five species associated with melting snow were recognized. A total of thirty four species were recorded, among them: Fuligo septica (L.) F. H. Wigg., and Lycogala epidendrum (L.) Fr. were the most common. Ten taxa were very rare. They were noticed only once. Lamproderma echinosporum Meyl. and Stemonitopsis gracilis (G. Lister) Nann.−Bremek. were recorded for the first time in Poland.

Opis:
Some alien woody species used in commercial forestry become invasive and, as invaders, cause major problems in natural and semi-natural ecosystems. However, the deliberate introduction of aliens can bring unintended negative changes also within areas of their cultivation. This paper presents the effects of the intentional introduction of the North-American Quercus rubra in European mixed Scots pine-Pedunculate oak forests (POFs): Querco roboris-Pinetum (W. Mat. 1981) J. Mat. 1988. Phytosociological data from field research combined with GIS data analysis of the current distribution of Northern Red oak in the studied habitat were used to determine the composition and structure of forest communities in plots with and without Q. rubra participation. The results show that Q. rubra significantly reduces native species richness and abundance, both in old-growth and in secondary (post-agricultural) forests. Not one resident vascular plant benefits from the introduction of Northern Red oak and only a few are able to tolerate its co-occurrence. The natural restocking of all native woody species is also strongly limited by this alien tree. The introduction of Northern Red oak significantly limits the environmental functions of the POF ecosystem and weakens its economic and social aspects. However, its further cultivation is justified from an economic point of view, as the essential function of the studied forests is commercial timber production, and the introduction of this fast growing alien tree supports the provisioning ecosystem services. A clear description of the level of trade-off between the accepted negative and positive effects of the introduction of Q. rubra on forest ecosystem services requires further interdisciplinary studies.

The paper presents a brief history and present state of Sorbus torminalis in Polish forests. It shows the history of research and conservation of this species and changes in conservation strategies and methods. The future of the species, concerning both conservation and cultivation context looks optimistically.
