    Opis:
    Monitoring of water ecosystems in Kazakhstan is based generally on chemical indicators. Biological indicators, such as macroinvertebrates and a phytoplankton are rarely used. Sometimes some macrophyte species of are used for the assessment of water quality. The aim of the study was to analyse the possibilities of the introduction of the Polish monitoring system based on aquatic plants for rivers in Kazakhstan watercourses. The Polish method uses the Macrophyte Index for Rivers (MIR) and it has been prepared for the purposes of the EU Water Framework Directive. The systematic structure of Kazakhstan’s water plants were analyzed and compared with the macrophyte list of Poland. Flora of Kazakhstan was used as the main source of information and some recent publications were analyzed as well. It was found that the aquatic flora of Kazakhstan is rich and a total of 240 taxa of emergent and submerged plants are identified in the country. We have confirmed that a large number of aquatic plants recorded in Kazakhstan are recognized as bioindicators. The ecological tolerance and sensitivity of the identified bioindicators was analysed. A preliminary nine taxa with the the highest indicator weight in the MIR system (W = 3) were detected as the most sensitive indicators in Kazakhstan flora: Sciuro-hypnum plumosum, Scapania sp., Ceratphyllum demersum, C. submersum, Potamogeton lucens, P. praelongus, Lemna gibba, Menyanthes trifoliata and Acorus calamus. It was found that the MIR index can be applied in Kazakhstan, especially if we enrich the list of indicative species with the local macrophytes, which were not included in the original version. The list of potential indicator-species includes: Ranunculus altaicus, Ranunculus natans, Althenia filiformis, Nelumbo nucifera, Trapa incise which does not occur in Europe and Nuphar pumila, Nymphoides peltata, Ranunculus rionii, Rorippa palustris, Trapa natans, Utricularia intermedia, U. minor, Eleocharis acicularis and Vallisneria spiralis.

    Opis:
    The research aimed to make an inventory of the vascular flora of 11 parks and gardens of the Pomeranian Cistercian Trail, with particular emphasis on taxa attached to old deciduous forests. A total of 62 species were registered, recognised as indicators of old deciduous forests in Poland. The presence of species of this group was confirmed in all of the analysed objects, but their number varied from 7 to 50. The group of ancient woodland species includes forest species for which the light indicator values are lower than or equal to 4 (plants of shadowy places, with a relative light intensity). The group of indicator species also includes forest geophytes and forest myrmecochores, autochores and barochores, as well as woodland species that can tolerate stress, under the classification of ecological strategy types S, S/CSR, S/SC and S/SR.

    Opis:
    Modern multifunctional forest management needs indicators showing the state of forest environment. Commonly used solution is monitoring of the abundance of species with specific environmental requirements. This paper analyses the possibility of use of the biggest European woodpecker (Dryocopus martius) as forest management quality indicator. The black woodpecker resides in all types of forest sites. The species prefers big thick trees as a nest trees, its cavities were mainly made in birches Betula sp. in Western and Southern Europe, Scots pines Pinus sylvestris in Middle and Eastern Europe and aspens Populus tremula in Northern Europe. The black woodpecker, excavating large−sized breeding cavities, is defined as a key species due to the creation of breeding sites for large secondary cavity−nesters. Because of the breeding requirements, black woodpecker can also be treated as an umbrella species for organisms associated with old trees. The way of feeding of that species shows a strong connection with the availability of dead wood. The black woodpecker is a sedentary species, which means that it is highly depended on the structure of the forest and quickly responds to changes caused by forest management. Because of the habitat requirements and relationships with other species, as well as the wide geographical range, it is a good indicator species for multifunctional suitable forest management. It can also act as a keystone species for secondary cavity nesters and umbrella species for organisms associated with old, dying trees.

    Opis:
    Presence of plant species, associated with ancient forests (continuous existence >200 years) can be used for assessing woodland biodiversity. The aim of this study is to specify which plant species, included in the ancient forests plant species list, can indicate old woodlands in parks and what plant features are characteristic for certain habitat types. Richest in ancient forest plant species are those fragments of woodlands, which have existed continuously for at least 120 years, and their fragments suffered least from human pressure during that time, whereas recent woodlands are characterized by a small share of ancient forest indicator species and domination of nitrophilous species. Investigated plants usually propagate vegetatively, their seeds are of a small size and they have regularly, densely set leaves. Plants associated with ancient woodlands are good indicators of woodland continuity in parks so they can be used for age assessment in these areas. Accumulation of such plants can be a useful criterion in parks evaluation. Proposed idea of sustainable management of a park space, including selection of areas of a great ecological value, can be a chance to preserve woodland biodiversity.

    Opis:
    During the survey of the Mały Borek nature reserve (Augustów Forest, NE Poland) 236 species of vascular plants were recorded, including 10 plant species red-listed in Poland and 19 species protected under the Polish law. The most valuable species were sedges typical of the boreal coniferous forests: Carex vaginata, C. globularis and C. loliacea. The presence of neophytes was very limited (1,3% of the flora) in the area studied. The principal aim of the establishment of the reserve was the conservation of old-growth coniferous forests with long ecological continuity. Since the reserve studied consists mainly of old-growth coniferous forests, the number of species regarded as ancient forest indicators is lower (54 species) than in the well-preserved reserves with deciduous stands in north-east Poland, but still rather high. The most valuable, threatened species are bound to wetland forests that are presently disturbed due to drainage. Restoration of the former hydrological conditions is essential for the preservation of the vascular plants in the reserve.

    Opis:
    The increase of Lyme borreliosis (LB) can be expected due to climate change, while the distribution of the disease and annual activity of the vector and host animals depend on several factors of the environment. The presented study aimed to assess expressly the spring season temperature dependence on the incidence of LB in Hungary. The weekly LB data were obtained from the National Epidemiologic and Surveillance System for a period of 13 years – 1998–2010. Daily temperature data were derived from the European Climate Assessment and Dataset. The association was studied at national level, descriptive statistics and linear regression models were applied. A significant increasing trend was observed in the mean temperature of the analysed years (0.052 °C per year). The annual LB incidence doubled during the 13 year period. The incidence rates of the periods 1998–2001 and 2007–2010 were 11.1 resp. 17.0 per 100,000. The start of a steep increase in weekly LB incidence (0.1 per 100,000) shifted significantly by 3 weeks earlier, the start date of spring showed similar trend (p=0.0041). LB incidence increased more steadily in spring than in summer, with 79% of the increase being reported during weeks 15–28, with maximum rates of increase occurring in weeks 23–25. The trend was significant between the weeks 15–28. In the warmer years with 19.02 °C mean temperature in May and June, the LB incidence curve reached the annual peak 2–3 weeks earlier, and the descending phase of the curve started earlier than in the colder years with 17.06 °C of the same period.

    Opis:
    This paper presents an overview of bird research carried out in the Borki Primeval Forest during the last 30 years. The Borki Primeval Forest can be considered as one of the most important forest bird sites in Poland. Its avifauna comprises 139 breeding species, including 11 rare and endangered species listed in the Polish Red Data Book of Animals as well as 30 species listed in Annex I of the EU Birds Directive. Despite its relatively small area, the Borki Primeval Forest holds at least 1% of Polish breeding population of as many as 12 bird species . For seven out of these species it is one of the most important breeding sites in the country. The avifauna of the Borki Primeval Forest consists mostly of typical forest birds including 24 indicator species which are associated with natural forests. The richness of bird species in the Borki Primeval Forest and the abundance of several valuable groups of breeding species are the result of a high landscape and habitat diversity as well as a relatively small anthropopression combined with a high degree of naturalness of forest stands.

    Opis:
    Gmina Uniejów to obszar rolniczy – ponad 80% jej powierzchni stanowią użytki rolne, a lesistość wynosi obecnie 10,6%. Jest to teren ubogi w lasy, które na obszarze gminy są w znacznym stopniu rozdrobnione, a ich roślinność antropogenicznie zaburzona. Brakuje większych kompleksów leśnych. W latach 2021–2022 przeprowadzono inwentaryzację flory w 33 wybranych losowo wyspach leśnych, których powierzchnia była mniejsza niż 10 ha. Oceniono przyrodniczą wartość badanych obiektów, wykorzystując gatunki wskaźnikowe („rośliny starych lasów”). W badanych wyspach leśnych odnotowano 21 gatunków roślin typowych dla starych lasów. W najbogatszym florystycznie obiekcie stwierdzono 10 gatunków wskaźnikowych dla starych lasów, a w najuboższych tylko po dwa tego typu taksony. Wyspy leśne gminy Uniejów cechują się małą liczbą gatunków typowych dla starych lasów. W większości są to obiekty wtórne na gruntach użytkowanych w przeszłości rolniczo.
    Uniejów agricultural landscapes dominate in the Uniejów municipality as farmland takes up more than 80% of the area, while woodland constitutes only 10.6% and is reduced to separate small wooded patches (islands) with anthropogenically impaired flora. No larger forest tracts survived there. In the years 2021–2022, the flora of 33 randomly chosen forest islands (less than 10 ha) was examined and listed, focusing particularly on species belonging to the group of “ancient woodland indicators”. Altogether 21 species of plants typical of old forests were identified in the area, out of which 10 species were found in the “richest” forest patch and only two in the poorest one. Generally, forest islands in the Uniejów municipality contain few species confined to old forests. The islands represent mostly recent secondary woods on the formerly agricultural land.

    The paper analyses the relationships between the microsite diversity of fresh coniferous forest and the number of Scots pine (Pinus sylvestris L.) seedlings from natural regeneration. The competition of forest floor vegetation (mainly of Vaccinium myrtillus) was found to be the decisive factor of pine regeneration. Lichens, especially Cladonia arbuscula and C. rangiferina, as well as mosses, e. g. broom moss (Dicranum scoparium) and pincushion moss (Leucobryum glaucum), can be regarded as the indicator species for the microsite suitable for pine regeneration.

    Opis:
    The utility of phytocenotic indices in the diagnosis and classification of forest sites might be limited because of vegetation degeneration in managed forests. However, even in secondary communities it may be possible to determine indicator species, although these may differ from typical and well known plant indicators. The aim of this work was to assess the vegetation diversity of Scots pine stands in representative forest site types along a moisture and fertility gradient. In total 120 sample plots from Turawa forests were included in the study. These plots represented young (21–40 years) and old (> 80 years) Scots-pine-dominated stands. The forest sites were categorized according to Polish site classification. Four site categories were studied: Boew (very nutrient-poor and mesic sites), BMoew (nutrient-poor and mesic sites), BMw (nutrient-poor and moist sites), LMw (quite nutrient-rich and moist sites). The species composition of the forest patches studied hardly differed among forest site types. Almost all of the vegetation in site Boew was different from both moist site types (BMw and LMw). Sites Boew andLMwhad the exclusive species determined as site indicators. Moreover, young stands had their own site type indicator species which differed from old stands. Numerical classification showed that only two plant communities were widespread: Leucobryo-Pinetum in Boew and BMoew, and the community of Pinus sylvestris and Molinia caerulea in BMoew, BMw, LMw. In secondary communities typical indicator species may not be useful, but it is possible to determinate species that are locally unique to forest site type. Despite the convergence in the composition of the plant community resulting from tree stand unification, plant communities have the capacity for a more diverse composition. Tree stand conversion can increase phytocenotic diversity.

    Opis:
    The paper presents the results of water trophy assessment from various stations of the cooling system of the “Dolna Odra” (Poland) power plant. The assessment was made based on the indicator phytoplankton species collected four times at four sites located in different parts of the hydrological system cooling the technical infrastructure of the power plant. The sites were characterised by water with a natural temperature for individual seasons, as well as by thermals changed as a result of the discharge of cooling waters. For each site, the saprobic index was calculated based on indicator species. The analysis showed that the changes in trophic conditions, both in waters with changed thermals and in waters not subject to the influence of after-cool waters, are not subject to significant changes. The waters of all studied sites in the analysed periods of the year should be classified according to Sladeček and Sládečková (1996) to the waters of the β–mesosaprobic zone, with a saprobic index value ranging from 1.51 to 2.50 (average S = 2.0). This zone is characterised by the course of biochemical processes under aerobic conditions, as a result of which complete oxidation of the intermediate products of decomposition of organic compounds takes place.
    W pracy przedstawiono wyniki oceny trofii wód z różnych stanowisk układu chłodniczego elektrowni „Dolna Odra” (Polska). Oceny dokonano w oparciu o wskaźnikowe gatunki fitoplanktonu zebranego w czterech terminach roku na czterech stanowiskach, zlokalizowanych w różnych częściach systemu hydrologicznego, schładzającego infrastrukturę techniczną elektrowni. Stanowiska charakteryzowały się wodami o temperaturze naturalnej dla poszczególnych pór roku, jak i zmienną termiką w wyniku zrzutu wód pochłodniczych. Dla każdego stanowiska obliczono indeks saprobowy na podstawie gatunków wskaźnikowych. Analiza wykazała, że zmiany w zakresie trofii, zarówno w wodach o zmienionej termice, jak i wodach nie podlegających oddziaływaniu wód pochodniczych, nie ulegają istotnym zmianom. Wody wszystkich badanych stanowisk w analizowanych okresach roku należy zaklasyfikować wg Sladeček i Sládečková (1996) do wód strefy β–me- zosaprobowej, mających wartość indeksu saprobowości w granicach od 1,51 do 2,50 (średnio S = 2,0). Strefa ta charakteryzuje się przebiegiem procesów biochemicznych w warunkach aerobowych, w wyniku których zachodzi całkowite utlenienie pośrednich produktów rozkładu związków organicznych.

    Opis:
    The resilience of forest ecosystems to climate changes such as elevated temperature and frequent drought episodes, strongly depends on how the soil subsystems and its inhabitants responds to these perturbation. The epigeic soil Collembola communities of mature mixed deciduous forest and adjacent young plantation on moderately humid soil were compared in two consecutive years, out of which the second one was marked by significant deficiency of precipitation in growing− −season. The study plots were established on the area of experimental forests of Warsaw University of Life Science−SGGW in Rogów (central Poland). The objectives of the study was to assess the sensitivity of forest Collembola communities to drought stress and to check if the reaction depends on stand age. We also aimed to test if an indicator species of climate changes can be appointed. The results showed that three months drought episode had negative impact on forest Collembola communities of mature stands, while communities of young plantation were not affected. The reduction of total abundance of Collembola and clear changes in communities structure in mature stand was detected in the year of lower precipitation. The Collembola communities of young plantation were also significantly transformed, but in result of clear cutting and soil preparation. Therefore, the successional changes were the most evident process in these communities and there were no signs of drought influence. Among the most numerous species in Collembola communities of mature forest Isotomiella minor was appointed as an indicator of drought, because its abundance was drastically reduced in the year of lower precipitation. The small number of specimen of this species in young plantation may also prove its sensitivity to deficiency of humidity in soil. The significantly negative response to drought episode was documented also for Psuedosinella horaki, Micraphorura absoloni and Megalothorax minimus. Our study provided strong evidence that the drought, which lasted only three months, had a detrimental effect on forest Collembola commu− nities.

    Opis:
    The paper presents the ecological indicator values for 360 lichen species noted in Poland. For the given species estimated were the climatic indicators (light, temperature, moisture) and the edaphic ones (trophicity, habitat acidity). The estimate is based mainly on field studies and Polish lichenological literature. Presented are also the dynamics tendencies, i.e expansion or dieback of the analyzed species. According to papers by Polish authors, concerning various groups of plants, used were five degrees' scales of the analysed indices.

    Opis:
    A numerical analysis of the phytosociological relevés from ancient and recent woodland on a mesic forest site in central Poland was carried out. Three groups of forest stands were recognised: planted with Pinus, recent and ancient oak-hornbeam Tilio-Carpinetum. The species of ancient woodland occurred mainly in ancient oak-hornbeam forest stands, however some ferns: Dryopteris carthusiana, D. dilatata and D. filix-mas, and an orchid species Epipactis helleborine, are to be found mainly or exclusively in recent forests. The occurrence of ancient forest species in recent woods may be putatively explained by long-distance wind dispersal or by the thriving in situ in unrecognised small wood patches. Twelve ancient woodland indicators (i.e. 36% of a total number found in the region under study) occur exclusively in ancient woodland. It underlines the role of passive species protection in the maintenance of the regional species diversity.

    Opis:
    Red osier dogwood Cornus sericea L. is a species native to North America, but spreading in Europe. It has been classified a kenophyte in Poland and is considered invasive. However, knowledge on its distribution is insufficient and lacking entirely for many parts of the country. Therefore, the aims of this study were to document stands of C. sericea in the buffer zone of the Skarpa Ursynowska nature reserve in Warsaw, to provide new information on morphological features that were inconsistently reported in the literature, and to summarise the known distribution of this species in the mazovian voivodeship. Field studies were carried out in 2021 within six new stands of C. sericea located in the buffer zone of Skarpa Ursynowska. The work included phytosociological relevés and measurement of the following parameters: length of leaves (blade and petiole) and the maximum height of plants. Based on the herb layer species found in the phytosociological relevés, ecological indicator values were calculated in order to determine habitat conditions. The distribution of the species in the mazovian voivodeship was then mapped by means of the ATPOL cartogram method. In the vicinity of the Skarpa Ursynowska, C. sericea occurred in scrub communities and at the early successional stages of forest development that is in habitats with favourable light conditions, sufficient humidity and fertility. The presence of a number of additional alien species was also a characteristic feature of the stands. C. sericea individuals identified in this survey were tall and showed almost no tendency to creep, most likely due to the favourable light conditions. Their leaves were larger (average length 189.2 mm) compared to published data, but the shape of the seeds was characteristic for the species. This is the first re- port of spontaneous occurrence of this species in Warsaw. The largest known concentration of C. sericea stands in the mazovian voivodeship was documented west of Warsaw and includes the Kampinos National Park. However, the small number of existing reports indicates that documentation of this species’ distribution in the region is still insufficient.

    Opis:
    Seslerio uliginosae-Scorzoneretum purpureae is the only xerothermic community of the Festuco-Brometea class, where a rare species known as Sesleria uliginosa occurs in Poland. A couple of sites hosting this association in the Nida Basin were described in the 1920s and 1950s. All these stands are now situated in the areas designated as xerothermic nature reserves. The study aimed at describing the present-day characteristics of this rare association, the most likely being endemic in Poland, as well as the changes that have occurred in it. The species diversity and the contribution of xerothermic plants have decreased significantly in terms of their number and cover coefficient. Some of the diagnostic species of the association have become extremely rare. Sesleria uliginosa is the only one without visible changes in their dominant position in the community. Mosses, that have played a significant role before, were among the vanished species. At the same time, an increase in number and cover of mesophilous meadows species was observed. Mesophilous grasses belong to the group of species growing in significance in the phytocoenoses. The observed changes in species composition were reflected in a statistically significant increase of nitrogen indicator value. The slow process of succession observed in the Seslerio-Scorzoneretum purpureae could be attributed to the lack of appropriate land use, e.g. mowing and grazing that have been ceased in the nature reserves.

    Opis:
    Vegetation of deciduous forests in the Štiavnické vrchy Mts (Central Slovakia) was studied using the standard Zürich-Montpellier approach. The numerical classification and ordination technique were applied to determine the main forest vegetation types and to find the responsible environmental drivers related to their distribution patterns, respectively. The data set including 198 relevés collected by authors in 1997-2009 and 185 relevés excerpted from literature was used to analysis. Numerical classification resulted in delimitation of fourteen vegetation types representing eleven associations with two variants and two communities within the Quercetea roboripetraeae and Querco-Fagetea classes. The major environmental gradients in variation of forest species composition were associated with moisture and nutrient content following the average Ellenberg indicator values. Along the moisture gradient, vegetation types were ordered from subxerophilous oak forests turn mesophilous mixed oak-hornbeam, beech and ravine forests to hygrophilous riparian alder forest. The results confirmed important role of soil nutrients and moisture by determination of forest vegetation in subcontinental part of Central Europe. Special attention was given to the discussion of floristical characteristics, site conditions and syntaxonomy.
