    Opis:
    Forests in Poland cover about 30% of the country’s area; most of them are public forests managed by the State Forest National Forest Holding. Some of them have protection status in order to perform specific functions related to their location. One of the essential categories of protection forests is located within the administrative borders of towns and near areas with more than 50,000 inhabitants. Such areas are significant from the social point of view, and their primary function is to create proper space for the inhabitants’ leisure and biodiversity protection. However, management in forests around towns is increasingly controversial, which in the area of the Regional Directorate of State Forests in Bialystok is manifested by more and more frequent conflict situations. In order to meet social expectations while effectively ensuring the continuity of the forests for future generations, a change in the way of forest management in and near cities is necessary. The key element is probably to develop a dialogue model with the local community to manage socially important forests efficiently and mitigate emerging social controversies.

    Opis:
    The article is a comparative study of the forests of the city of Poznań and the State Forests in Poland concerning functions of forests and forestry management (recreational development, economic division, harvest cutting, fellings, renewals, afforestation and the type of the forest management plan). The study objective is to demonstrate and analyse the basic differences in the function and management method between urban and state forests. In Poland 77.3% of forests are administrated by the State Forests National Forest Holding, while the urban forests constitute only by 0.2% of all Polish forests. They differ not only in terms of ownership and participation, but also in the species and age structure of the stands, their functions and principles of forest management. There is no appropriate instructions concerning the principles of the management in urban forests, whereas this problem does not appear in the State Forests. However, irrespective to the owner, a common definition of 'forest' is included in the Forest Act. Regulations relating to forest management in the forests of the city of Poznań are a reflection of the expectations of society that urban forests are for residents of the city, primarily a place to satisfy their needs of rest and recreation. It was the reason for adapting the principles of forest management. In contrast, forests managed by the State Forests are governed by completely different rules and perspective on forest. It results in a different structure of forest functions, the occupied area and legal requirements concerning this group of Polish forests. Foresters from the State Forests conducting forest management have clearly defined rules that are missing for other Polish urban forests. Excluding city of Poznań that is a very good example that one can meet the expectations of the foresters of urban forests and offer guidance on forest management, taking into consideration the specificities of urban forests and the expectations of society.

    Opis:
    The study conducted in the years 2011–2014 were selected mid – forest meadow located in Urban Forests in Szczecin in the vicinity of the Plonia River mucky soils. On the analyzed objects were found three communities type Alopecurus pratensis (two), Festuca rubra and Alopecurus pratensis with Calamagrostis canescens. The nature of plant indicates their low economic value and moderate natural values; However, they meet many ecological functions, natural and landscape.
    Do badań przeprowadzonych w latach 2011–2014 wybrano łąkę śródleśną zlokalizowaną na terenie lasów miejskich w Szczecinie na glebie murszowatej w sąsiedztwie rzeki Płoni. Na analizowanych obiektach stwierdzono występowanie trzech zbiorowisk: dwa typu Alopecurus pratensis, Festuca rubra oraz Alopecurus pratensis z Calamagrostis canescens. Charakter zbiorowisk roślinnych wskazuje na ich małą wartość gospodarczą i umiarkowane walory przyrodnicze. Pełnią one jednak wiele funkcji ekologicznych, przyrodniczych i krajobrazowych.

    Opis:
    Urban river valleys are exposed to strong anthropogenic pressure, but despite these distortions they provide important habitats in urban areas. Not embanked forests are particularly valuable in urban river valleys as they represent fragments of natural vegetation in a highly changed environment. The study assesses the flora and structure of forest communities in a riparian urban forest complex that is under the direct influence of river water. Las Pilczycki Forest in Wrocław (SW Poland) is such a riparian forest island. We analysed the species richness and composition in terms of the phytocoenoses variability and their syntaxonomic classification. We also investigated if the vegetation can indicate a spatial differentiation in habitat conditions. Floristic and phytosociological data were collected from 70 circular plots (100 m&suo2; each) located in a grid. A total of 81 species were recorded, with a mean of 21 species per plot. Most frequent were: Acer campestre, Acer platanoides, Anemone nemorosa, Ficaria verna, Fraxinus excelsior, Galium aparine, Geum urbanum, Impatiens parviflora and Sambucus nigra. In biological spectrum the most numerous were hemicryptophytes, megaphanerophytes and geophytes. The number of alien species was minor (9% of the flora). The most frequent anthropophyte was Impatiens parviflora. Soil moisture, acidity and fertility indices exhibited spatial correlations and they were higher in the western part of the forest. The moisture index was also higher in the northern part. Species richness ranged from 13 to 32 (with a mean of 21 species). Two forms of Ficario−Ulmetum minoris were identified: with Galanthus nivalis and with Tilia cordata. The first was a well−structured riparian community, while the latter one represented the drained floodplain forest. Vegetation units are spatially separated, in the western part of the forest prevails form with Galanthus nivalis, while in the east – with Tilia cordata. In isolated alluvial forests of urban area local site conditions are crucial for the vegetation patches, because of the distortion of river valleys. The absence of flood embankments is not a sufficient condition for maintaining proper structure of riparian forests.
