    Opis:
    During the period from 2003 to 2011 observations of carabid community regression and selected habitat indicators were conducted on 15 plots in stands that had been disturbed by a hurricane and on 15 plots in control stands. Regression of carabid communities delayed 3−4 years was observed, consisting in increases in the number of species and the proportion of xerophilous species and reductions in the percentage of forest fauna and in mean individual biomass. Only after 7 years did these indicators begin to show a tendency in the reverse direction, albeit not very strong, indicating that carabid communities had begun to regenerate.

    Opis:
    We studied the relationship between tree-species diversity and the above-ground biomass on an example of two natural Polish forest with different altitiudinal range, plant species pool, vegetation and climatic conditions. The study sought to determine whether: (1) above-ground biomass in natural forests correlates with tree-species diversity irrespective of the kind of forest (montane or lowland), and (2) the relationship in question is negative, (3) the above-ground biomass is greater in montane forests than in lowland ones. Natural forests present in 1º Polish Gorce Mountains (montane forest) alongside comparable data for the 2º world-renowned lowland forest that is present in the Białowieża National Park. Data were collected within 558 sample plots (á 200-square-metre). The diameter at breast height of all trees with girths of or exceeding 12 cm was measured. To compute above-ground biomass we calculated dry masses for each tree on the basis of values for dbh and height, next we summed these values for all species present within each plot. The number of tree species on a plot ranged from only one (mainly in spruce stands) to six (in mixed deciduous lowland forest stands). The above-ground accumulated biomass ranged from 6 to 1155 (average 251±13) t ha–1 within the lowland forest, and from 2 to 849 (average 242±8) t ha–1 within the montane forest. We concluded that there was a humped-back shaped relationship between tree-species diversity and above-ground biomass in both lowland and montane natural forests.

    Opis:
    The study aimed to investigate effectiveness of forest management zoning in conserving biodiversity of Mabira forest reserve. The study sites buffer, production, and strict nature reserve management zones were purposively selected. This was undertaken through investigating woody species diversity, composition and structure. A total of 60 sampling plots with a size of 20 m x10 m were used to collect vegetation data. Variables such as woody plant species identification and counts as well as diameter at breast height (DBH) of trees were done. The result depicted a total of 65 woody species; 39 in buffer, 19 in productions and 37 in strict nature reserve. Of these, only 9 trees species were found common to all zones and their Sorensen similarity coefficient was 0.2213. The population structure of the buffer and strict nature reserve zones was found to be a J - shape pattern, whereas the production zone shown an inverted J-shape pattern. Higher woody species diversity was depicted in the buffer and strict nature zones with (H’=2. 73512) and (H’=2. 68412) respectively, and lower in a production zone (H’=1. 63628). The evenness index value of a buffer zone was (J =0. 746574), strict nature (J= 0.743335) and production (J=0. 555719). The production zone had shown higher IVI values followed by buffer and strict nature reserve zone. The most important woody species identified based on their IVI value were Broussonetia papyrifera (Production), Acalypha neptunica (Buffer), Funtumia Elastica (strict nature reserve). The existing forest management is effective in conserving the biodiversity of the forest reserve. Nevertheless, the production zone was still suffering from exploitation of the surrounding community, hence serve for protecting the remaining management zones from further human interference. Further investigation is also required on the adjacent community perceptions of the forest management zoning.

    Opis:
    The paper presents socio-ecological and ecological characterisation of 72 bryophyte species found in the years 2008-2012 on midforest roads passing through nine nature reserves situated in the Łódź region. Nine species occurred excl usively in this habitat. Most of the species noted (63%) were forest bryophytes occurring also inside the forest phytocoenoses studied, they constituted 95.5% of all the records. The non-forest species show diff erent socio-ecological relations: some of them occur typically on meadows or in grassy forest ecotones, others – in fens or bogs but there are also some pioneer bryophytes colonizing initial sites, both of natural and anthropogenic character. They diff er from the forest species occurring on midforest roads in their ecological demands regarding the habitat reaction (presence of subneutral species) and light (higher participation of heliophytes). Nine of them (13%) are considered to be synanthropic bryophytes. Details of the species occurrence are provided.

    Opis:
    Fire usually causes changes in the composition and diversity of herbaceous species. The present paper aimed to study the effect of repeated fire incidents on understory species diversity in the Saravan forests of Guilan Province located in the north of Iran. To do so, three 50-hectare areas with identical physiographical conditions and overstory (hand-planted softwood Pinus taeda) were selected. Seven fire incidences occurred for the 10-year period in one of the areas and the other area experienced three fire incidents within the same period. The area with no fire incidents was considered as the control area. All the fire incidents were surface ones. The systematic random method with a sample size 100 × 200 m was used for collecting data. Based on the above, 25 samples were determined in each area. The whole coverage of the understory was taken into consideration using Whittaker’s method and the Domain criterion so as to calculate species diversity indices. The results showed that Shannon-Wiener diversity and Menhinick’s richness in the regions which experienced 3 and 7 fire incidents were maximum and minimum, respectively, whereas no significant difference was seen between the regions with regard to Smith and Wilson’s evenness index.

This study uses quantitative forest surveys, interviews, discussions, and descriptions of the historical context of public participation in forest management including a detailed assessment of field conditions. The findings of a forest resources inventory show that (1) from the three sampled areas, Doi Laung Wildlife Sanctuary has highest richness, followed by village #16 and #14, and (2) Huaikhon #16 implied the process of framework to maintain a healthy condition and response to community needs with collective management. The conceptual model assessment that links key group indicators and drivers is presented based on previously developed assessment models. The framework focuses on the best way to provide forest management, forest fire prevention, and firefighting as well as monitoring of Check-dam construction and other activities that support the recovery of the forest community. This paper demonstrates the general of an environmental assessment framework to applying organize environmental information to facilitate policy decision making for the sustainable development.

    Opis:
    This paper presents the results of floristic studies conducted in the years 2003 – 2005 within the area of the Polesie National Park. The aim of the research was to compare the flora of initial succession stages in drainage ditches with the flora of neighbouring forest areas undergoing transformation as a result of drainage. Floristic lists were made in four designated study areas as well as in forest phytocoenoses. The results of field investigations were subjected to analysis with regard to the systematic affinity of the flora and proportions of plant life-forms as well as of historical-geographical groups and range groups. In the species composition of the studied drainage ditches hemicryptophytes were the dominant group of plant higher life-forms, whereas in the neighbouring communities the flora was represented by both hemicryptophytes and megaphanerophytes. In historical and geographical terms, the flora of drainage ditches and neighbouring communities represents definitely the group of spontaneophytes. Anthropogenic habitats, which developed within the drainage ditches, were colonised by native flora species characteristic for the Polesie National Park area.
    Praca przedstawia wyniki badań florystycznych prowadzonych w latach 2003–2005 na terenie Poleskiego Parku Narodowego. Celem niniejszej pracy było porównanie flory inicjalnych stadiów sukcesyjnych w rowach melioracyjnych, z florą przekształcających się wskutek odwodnienia, sąsiadujących terenów leśnymi. Na czterech wyznaczonych powierzchniach badań, a także w fitocenozach leśnych sporządzono spisy florystyczne. Wyniki badań terenowych poddano analizie kameralnej pod kątem przynależności systematycznej flory, udziału form życiowych roślin, a także grup historyczno-geograficznych i grup zasięgowych. W składzie gatunkowym, badanych rowów melioracyjnych dominującą grupą form życiowych roślin wyższych są hemikryptofity, podczas gdy w zbiorowiskach sąsiadujących z nimi florę reprezentują zarówno hemikryptofity jak i megafanerofity. Pod względem historyczno-geograficznym flora rowów melioracyjnych, jak i zbiorowisk sąsiadujących, reprezentuje zdecydowanie grupę spontaneofitów. Antropogeniczne siedliska, jakie wykształciły się w obrębie rowów melioracyjnych zasiedlone zostały przez gatunki flory rodzimej charakterystyczne dla terenu Poleskiego Parku Narodowego.

    Opis:
    A Scots pine forest, affected by the great cormorant colony, was studied by plot-based fungal survey method during the years 2010-2012 in Lithuania. Diversity and composition of fungal communities were investigated at five zones that had been influenced by different stages of breeding colony establishment: starting-point and almost abandoned cormorant colony part (zones A and B), active part (zones C and D), and the edge of the colony (zone E). The control zone G in undamaged by cormorants pine stand was assessed too. A total of 257 fungal species of ascomycetes including anamorphic fungi, basidiomycetes and zygomycetes were recorded. Seven species were registered for the first time in Lithuania. Species richness in the examined zones varied, lowest being in zones B (51 species), C (46) and D (73) and almost twice as high in the zones A and E (129 and 120, respectively). The comparison of fungal species compositions of different zones showed that their similarity was rather low (SS: 0.22–0.59). The most obvious changes in the trophic structure of fungal communities in the territory occupied by the bird colony were a strong decrease of mycorrhizal species, the presence of coprophilous fungi on forest litter, and the appearance of host-specialized fungi on alien and non-forest plants that have established in the disturbed forest.

    Opis:
    This study present species composition and potential of litter on carbon and nitrogen return in secondary mixed deciduous forest after shifting cultivation. The dominant species of trees were Haldina cordifolia, Albizia odoratissima and Lagerstroemia duperreana. The Important Value Index (IVI) values of trees were 132.91, 17.78 and 14.22, respectively. The pattern for the decomposition coefficients (k) was highest in the wet period (May–September) and lowest in the dry period (October–April). The carbon and nitrogen return patterns increased in the dry period (October– April) and decreased in the wet period (May–September). Carbon and nitrogen loss in the decomposing litter continually decreased during the decomposition process from the initial levels, with a final relatively rapid release in the wet period. Results from this study was understanding of community composition, litterfall production and litter decomposition for understanding potential of secondary mixed deciduous forest for balancing carbon for mitigating greenhouse gas effect in the local area.

    Opis:
    Forest edges generally represent a very important element of ecological stability. The goal of this paper is to classify the types of anthropogenic forest edges in the area of Starohorské Mountains and to analyze anthropogenic impacts on the selected attributes of forest edges. We evaluated the attributes of a biocomplex, type of forest edge, its structure, consistence, species composition and other factors. The differences in environment variables and anthropic impact were influenced by singularities in the composition and species variability of vegetation. In the monitored areas we defined seven types and four subtypes of forest edges according to its vertical and horizontal structure. With the help of detrended correspondence analysis (DCA) we also interpreted organization relevés and species by gradients of environment variables, and with the help of canonical correspondence analysis (CCA) we tested their statistical significance. From the results of our research, there is a clear tendency for high diversity of living species in the forest edge. Environmental variables interpreting the highest volume of species variability are the altitude and transect position.

    Opis:
    The paper presents the list of 159 taxa, including 151 lichens and 8 saprotrophic or parasitic (lichenicolous) fungi, recorded in the designed Special Area of Conservation NATURA 2000 „Middle Łyna River Valley – Smolajny” (the Forest Division of Wichrowo). The analysed area (2953 ha) covers mostly forest communities, with natural character, associated with the valley of the Łyna river (hillside lime-oak-hornbeam forests, streamside alder-ash forest, riparian black alder forest).
    Praca przedstawia wyniki badań lichenologicznych przeprowadzonych w dniach 6-8 września 2011 r. w ramach sesji terenowej towarzyszącej 25 Zjazdowi Lichenologów Polskich, który odbywał się w Medynach koło Lidzbarka Warmińskiego. Celem sesji było poznanie zasobów gatunkowych porostów położonych na terenie Lasów Wichrowskich (Nadleśnictwo Wichrowo), istniejących lub projektowanych, Specjalnych Obszarów Ochrony Siedlisk (SOOS) Natura 2000. W tej pracy przedstawiono wyniki inwentaryzacji przeprowadzonej na obszarze zaproponowanego do utworzenia SOOS „Dolina Środkowej Łyny – Smolajny”. Obszar o powierzchni 2953 ha obejmuje głównie zbiorowiska leśne, związane z przełomowym odcinkiem rzeki Łyny (grądy typowe, grądy zboczowe, łęgi, olsy). Na analizowanym terenie znaleziono 159 taksonów, w tym 151 gatunków porostów (grzybów zlichenizowanych) oraz 8 gatunków grzybów saprotroficznych lub pasożytniczych (naporostowych). Biota ta obejmuje 19 taksonów objętych w Polsce ochroną oraz 57 zagrożonych w skali kraju wymarciem. Ponadto, stwierdzono gatunki znane dotychczas w kraju z bardzo nielicznych stanowisk, do któ- rych można zaliczyć: Bacidia hemipolia f. pallida, Biatora chrysantha, B. pontica, Biatoridium monasteriense, Fellhaneropsis vezdae, Lecanora farinaria. Na podstawie uzyskanych wyników można stwierdzić, że analizowany fragment Lasów Wichrowskich, na tle innych kompleksów leśnych Warmii i Mazur nie objętych dotychczas ochroną rezerwatową, wykazuje ponadprzeciętne wartości lichenologiczne, które zasługują na ochronę.

    Opis:
    The goal of the present research was to find correlations between the topographic attributes of a river valley and local ground-floor vegetation and its habitat requirements expressed by ecological indicator values (EIV), using the geographical information systems (GIS), digital elevation model (DEM), and multivariate statistical analysis. We paid special attention to the river course, which determines the differentiation in slope aspects and the amount of solar radiation reaching the ground surface. The model object was an almost latitudinal, ca. 4-km-long break section of the Sopot river, crossing the escarpment zone of the Central Roztocze Highlands, southeastern Poland. The main material comprised species lists (with estimated abundance) for each ca. 200-m-long section, according to the river valley course, separately for the left and right riverbanks, 40 sections altogether, ca. 15 000 vegetation records, and physical and chemical soil measurements. A 3-meter resolution DEM was derived from a 1:10 000 topographic map. We calculated the correlations between the topographic attributes of the valley, species richness, and the EIVs for all the species recognized in each section of the valley. We found 241 herb plant species in the ground-floor vegetation of the study area. We did not find significant differences between the two riversides (61 ±13 species per one section for the left and 63 ±17 for the right side). Thus, the parallel course of the river valley does not change the species richness on a more “sunny” and more “shiny” riverbank. However, this factor “cooperating” with other topographic attributes of the valley significantly differentiates the shape of species showing various requirements for basic habitat resources: light, moisture, soil trophy, reaction, dispersion, and organic-matter content.

    Opis:
    The influence of the edge effect on the meadow vegetation pattern was studied in the forest glades in the central part of the Middle Sudety Mts. (SW Poland). The spectacular edge effect is seen in the range of 4 m from the forest border towards the center of the glades. Within that belt we observed decrease in tree and bush species number, increase in share of graminoids and Fabaceae species, as well as increase in share of species generally related to grassland communities. A significant increase in species number and values of Shannon−Wiener diversity index was noticed within the distance of eight meters from the edges of glades.

    Opis:
    To evaluate the geographic variability of Pinus sylvestris populations seven morphological traits of needles of pines from IUFRO 1982 provenance trial have been analyzed. The studied populations originated from northern (>55°N in Russia, Sweden and Latvia), central (55-47°N in Poland, Germany, Belgium, France, Slovakia) andsouthern (<47°N in Hungary, Bosnia, Montenegro andTurkey) European ranges of Scots pine. The analyzedprovenance trial experimental areas were locatedin Kórnik (western Poland) andin Supraśl (north-eastern Poland). The greatest variation was found in needle length and number of stomata rows on the flat and convex side of a needle, whereas number of stomata per 2mmof needle length on flat and convex side of a needle was stable, with minor interpopulational variation. Biometrical analyses revealed a significant population × location interaction anda geographical pattern in interpopulational differentiation in both experimental sites, with the northern andsouthern European Scots pine groups of provenancesdiffering significantly from the group of central origin. The results obtainedare compatible with previous results of studies on provenance variability of the Scots pine from IUFRO 1982. In the light of available data, the influence of the Balkan glacial refugia of Pinus sylvestris on a present genetic diversity of this species in Europe and the reconstruction of Scots pine migration routes after the last glacial period are discussed.

    Opis:
    The paper presents the results of a lichenological study conducted in 2012 in the 'Lekowo' forest complex, situated in the north-western part of Mazovia (Forest Division of Ciechanów). It is the largest forest complex in the area, covering 1596 ha. The research area comprises two small nature reserves ('Lekowo' – 5.31 ha, and 'Modła' – 9.36 ha) with old-growth oak trees (160–200 years of age) and adjacent managed pine forests (76-107 years of age). The aim of this study was to investigate the species composition of the lichen biota in both reserves and to determine the role of nature reserves in preserving lichen diversity. Results of the study showed that old-growth stands, in particular those composed of oak trees above recommended felling age, provide habitats for a large group of stenotopic forest lichens which are absent in managed forests. The 'Lekowo' and 'Modła' nature reserves, despite their small areas, are valuable refuges that help to conserve remarkable lichen diversity at the local scale, and serve as potential diaspore sources for many rare and threatened lichen species.
