    Opis:
    In Poland, the public believes that the main objective of urban forests is rather to conduct forest management focused on the recreational needs of residents than to produce timber. Considering this belief, it becomes reasonable to distinct the principles of forest management in urban forests from those related to the forests of the State Forests National Forest Holding. Because of the permanent presence of people in the city woods, the managing authorities of such areas should also educate the residents, while forest management should be subordinated to social functions, especially the recreational one. However, Poland lacks the unified system of managing the urban forests, not only at the national scale (there is no central independent organizational unit), but also at the level of individual cities, where various municipal units manage urban woodlands. In practice, each city has its own, individual solutions in this regard. The governing bodies of urban forests face with many problems in their activity. These problems are associated with a strong process of urbanization and human pressure on forest areas, while on the other hand there are no formal legal basis (laws, regulations, instructions) relating the municipal forests. The paper reviews the literature on urban forestry and urban forests worldwide to present the existing legislative frameworks and to propose some changes, based on the current Act on Forest. It was stated that urban forestry in Poland is located in its ‘narrow' definition, based on the traditional forestry, giving priority to the multiple social functions. The proposed changes in forest legislation are part of the discussion on municipal forests and urban forestry in Poland, aiming once again to draw attention to the fact that they are almost ignored in the Polish legislation. The indicated areas for improvements and supplements suggest issues the most important and urgent to solve, but they are not a comprehensive solution on this subject. In order to strengthen the supervision of urban forests in Poland, it is essential to consider the restoration of central supervision, coor− dinating activities of urban foresters by the development and implementation to the practice unified legal regulations, as well as to give wide autonomy to cities.

    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.

    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.
