The Niepołomice Primeval Forest is a valuable natural object playing an essential environment-forming role in the urbanized and industrialized Region of Kraków. It is situated in the western part of the Sandomierz Basin and characterized by geomorphological differentiation, typical for this region, as well as by abundanee of animated nature. The vegetation cover of the Forest are the lowland leafy forests, fertile, dampish meadows and marshy coniferous forests. In the surroundings of the Forest there are also some valuable regions of meadows. Of great value are also both lowland and high bogs. The Niepołomice Forest and its surroundings is a place of occurrence of many floral rarities, e.g. Betula humilis, Daphne mezerum, Hedera helix, Osmunda regalis, and others. The Forest is also an important fauna refuge with relict forest features. There are also many relict species which are rare in our country and even in Europe, e.g. Aquila pomarina, Tringa ochropus, Asio flammeus, Cerambyx cerdo, as well as an exceptionally great number of many, more vulgar species. The Niepołomice Primeval Forest and its surroundings connected for ages with the history of Poland, has also some considerable cultural values. The foundation of Niepołomice connected with the use of the Forest, was in the past a large monarchal estate and now is a valuable example of medieval town-planning. The present forms of protecting the Niepołomice Forest do not protect it from the detrimental influence of the management exerted by the Forest irself and in its surroundings. The greatest endangerement is the air pollution and changes in the water conditions. In order to protect the Forest from degradation of the values of this region, it is indispensable to use the legislative protection. Various possible forms of protection have been considered, recognizing that the effective protection of the Forest and its surroundings, without excluding the economic use of these areas, could be attained by enclosing the Forest within the boundaries of the Landscape Park and enlargement of the reserve. network. The physical extent of the Park has been designated, adopting the following criteriae: 1. The boundaries of the Park should comprise the areas connected with the Niepotomice Forest from the standpoint of the nature, landscape and culture. However, the surrounding areas, even if they are of high value but do not fulfil the condition of a close connection with the Forest, should not be included to the boundaries of the Park. 2. The boundary lines of the Park should ensure the protection of the most valuable natural and cultural elements of the Niepotomice Forest and its surroundings. 3. The Park should protect the entity of the ecological system by close connection with the ecosystems of the Niepotomice Forest. In order to realize an effective protection of the Park, a system of interdictions, com­mands and recommendations has been established and the physical structure has been designed for three zones: A. The sone of the highest natural values protected from any kind of investment at all. B. The zone of values of the natural and cultural environment having a rural character, protected from an excessive dispersion of houses. C. The urban zone of the highest cultural values requiring the preservation of the scale of the town and of its characteristic physical structure.

The aim of this paper was to determine the dry mass content in the fresh mass of leaves, trunks or branches and in the total woody aboveground biomass of shrubs forming the undergrowth of the stands in the Niepołomice Forest (southern Poland). The variability of the dry mass content in the analysed components was determined. For the prevailing species also its correlation with the individual's height and time at which samples were taken was investigated. The material comprised 744 samples, including 532 wood and 212 leaf samples, taken from the most common five shrub species: Corylus avellana, Frangula alnus, Padus avium, Padus serotina and Sorbus aucuparia. The shrubs were from 1 to 33 years old, and their height ranged from 0.3 to 9.9 m. It was shown that the dry mass content in leaves is significantly dependent on the shrub species, and in the case of F. alnus, P. avium and S. aucuparia on the height as well. The highest dry mass content was found in the leaves of C. avellana (39.3%), whereas the lowest – in F. alnus (25.5%). In case of F. alnus, the dry mass content depends on the time of sampling. The leaves collected in June had a significantly lower dry mass content than the ones sampled in subsequent months of the growing season. The dry mass content in the wood significantly depends on the shrub species and the analysed component, however the species−component interaction does not occur (tab. 4). The dry mass content in the trunk wood ranges from 50.3 (P. serotina and S. aucuparia) to 53.0% (P. avium) and exceeds that of the branch by from 1.0 (S. aucuparia) to 4.0% (P. avium). In the wood samples of F. alnus and S. aucuparia, taken between June and September, the dry mass content averaged at 47.3 and 48.7%, respectively, and was lower than in the samples taken between October and April, for which the respective means were 49.5 and 49.0%. In the case of F. alnus, the observed difference in the mean dry mass content is statistically significant at 0.05 level. The determined values of dry mass content in the fresh mass of individual components of the analysed shrubs can be used to find their dry mass as a basis for the calculation of the amount of accumulated carbon.

The objective of the study was to compare the seven tree species in terms of their role in the formation of a complex vertical structure in mixed broadleaved stands. The data came from 18 multi−storey old−growth forests representing different communities of lowland deciduous forests in the Niepołomice Forest. In each stand, squared sample plot (80×80 m) was established. The height of trees of dbh≥7 cm was measured. Then, for each studied species, values of the two structural indices were determined. The structural diversity index (ZS) quantifies tree height variation within individual population, whereas the index of structure−forming role (RS) expresses the contribution of the given population into vertical structural diversity of the whole stand. The greatest tendency to form a population with a large height diversity belonged to Tilia cordata, Fraxinus excelsior and Ulmus laevis. Significant opportunities in this regard, however, were exhibited by other tree species, including shade−intolerant Pinus sylvestris and Alnus glutinosa. This phenomenon in the conditions of eutrophic habitats, with the constantly present competitive pressure from shade−tolerant species, should be considered as an exceptional. A major contribution to vertical structural diversity of the stand was often an attribute of the populations with a low internal height diversity, which concerned especially Quercus robur. This means that an important ecological mechanism responsible for the formation of a multi−layer canopy is complementary filling the space above ground by trees of the species with different light requirements. However, the lack of correlation between RS and ZS indices suggests that the ability of particular species to form the population with a high internal diversity is equally important. The results prove the possibility of forming stands with a very complex vertical structure in the conditions of lowland mixed deciduous forests. However, in terms of sustainable maintenance of such stand structure, the issue of the growth rate of trees at different competitive pressure and the nature of their response to the release at different stages of ontogeny remains open.

The understory, a layer composed predominantly of shrubs that perform an important phytomeliorative function, has rarely been the subject of research on the productivity and biomass. The aim of this paper was to specify the occurrence of understory aged ≥10 years as well as its species composition and the share of individual species in the biomass in the Niepołomice Forest (S Poland). The analysed features were related to the age and site conditions of the stands. The research material consisted of dry biomass of shrubs growing within circular sample plots spaced 500 m apart from each other. Dead and live (damaged and undamaged) shrubs of dbh<7 cm were cut at a ground level to determine their wet mass and samples were taken to determine the dry mass. The mass of live shrubs was calculated based on empirical formulas. 368 sample plots were set up in total. Shrubs (13 species) were observed on 76.1% of plots. Shrubs were the most common in the stands of II and IV age groups (87% of plots). No shrubs were observed on the plots with stands older than 160 years. The most common species was Frangula alnus (56.8% of the plots). Quite common ones included Sorbus aucuparia (27.7%) and Padus avium (12.8%). Cornus sanguinea, Prunus spinosa, Salix caprea and Viburnum opulus were observed on less than 1% of the sample plots. Frangula alnus and Padus avium were inventoried in as many as 8 forest site types. The largest amount of shrubs (10 species) were observed in moist broadleaved forest stands, while the fewest (2 species) in boggy mixed broadleaved and ash−alder swamp stands. Over 56% of the aboveground biomass were live shrubs of dbh <7 cm (868.6 kg/ha), almost 29% (444.1 kg/ha) were shrubs of the dbh ≥7 cm, and around 15% (227.6 kg/ha) of the biomass were dead shrubs. The total aboveground biomass of shrubs in the understory of the analysed stands equaled, on average, to 1,540 kg/ha. 94% of the biomass was the aboveground woody biomass including bark (1,448 kg/ha). The dry mass of leaves amounted to 92 kg/ha (6%). Due to high variability of the understory biomass, the estimation error of its average amount was almost 11.4% for total biomass and 13.5% for leaves.
