Opis:
Habitat preferences of capercaillie Tetrao urogallus in the Augustowska Forest (NE Poland) were evaluated using classification trees. Data were collected on 1033 circular sampling plots localized on leks and in their vicinity with 1 km radius. Gathered information described tree stands (site conditions, age, species composition, tree density, closure, vertical structure, lower strata coverage (saplings and shrubs) and blueberry coverage (Vaccinium myrtillus) as well signs of capercaillie presence. The analysis shows that for capercaillie of key importance are tree stands growing on fresh or wet coniferous sites, more than 100 years old, with density less than 446 trees/ha, with anthill and situated more than 150 from a road.

Opis:
Analyses concerned the spatial characteristics of black stork nesting in relation to the occupied habitats and nest distance to chosen landscape elements. No essential changes were found in nesting characteristics between analysed periods of 1983−1989 and 1999−2008. Storks mostly located nests on oaks, birches and alders. In the direct vicinity of a nest, pine and fir stands (or alder in damp habitats) dominated. There were no statistically essential differences (p>0.05) between nest distances to the same landscape element in both analysed periods. Storks kept the biggest distance to routes and large potential foraging areas. Distance to settlements was similar to other stork nests.

Opis:
The state of the flora of the Biele nature reserve (Sokołów Podlaski Forest District) after 20 years of nature conservation was assessed. Only one species noted in 1989 was not confirmed at present, whereas 38 newcomers were observed. Most of them (30 species) prefer light and half−light/light conditions and are mainly related to non−forest communities. Frequency of synanthropic species is still very low (2.4%) and no anthropophytes were noted in the reserve. All protected and endangered plants, eg. Trollius europaeus, Gladiolus imbricatus, Dactylorhiza fuchsii, except of Carex umbrosa, still occur within its borders. Active protection of Trollius europaeus and Gladiolus imbricatus by removal of brushwood was suggested.

Opis:
The data on the distribution and number of the capercaillie Tetrao urogallus in Poland for the period from the end of the 20th century up to 2017−2018 is presented. The capercaillie is a sedentary forest grouse living in old mountain forests and within the boreal zone. Since more than a century, the decrease in the numbers of the species has been observed, interlinked with the extinction of isolated populations. Within the present borders of Poland, a 1925 questionnaire study noted 2200−2700 individuals. In the 1960s, the national population was estimated at 1700−2000 birds, living in five isolated populations. In 1985−1995, the population numbers of the capercaillie dropped to approx. 466−700 individuals in four regions, and in 2000 it was estimated at 470−570 birds. According to the results of the censuses performed in 2017−2018, the size of the capercaillie population risen to 523−631 individuals and 59−69 lekking grounds. Currently the capercaillie occurs in four isolated regions. These are the Western Carpathians (the Beskid Sądecki, Tatry, Gorce, Babia Góra, Beskid Żywiecki, and the Beskid Śląski ranges) where 284−326 individuals live and 35−41 leks are active. In the Solska and the Lasy Janowskie Forests (Lublin region), the population was estimated at 132−184 individuals and 12−13 lekking grounds. In the Augu− stów Forest (Podlasie region) 36−46 individuals and 5−7 leks were found. In the Bory Dolnośląskie Forest, where native capercaillies got extinct during the last decade, the reintroduction program resulted in the rebuilding of their 65−75 population (with 6−7 leks). The restitution of the species in the Piska Forest has begun. During the last 20 years, populations in the Carpathian national parks have been stable, although fluctuating in numbers. The increase in the number of individuals in the Augustów Forest as well as in the Sądecki and Beskid Śląski Mountains is an after−effect of the release of birds from breeding centers or translocations. In other strongholds, fluctuations or decreases have been recorded, including wisible in the Beskid Żywiecki Mountains.

Opis:
The objective of this paper is to analyse the forest habitat selection by Capercaillie in Polish part of the Western Carpathians. The study was carried out in the Ujsoły Forest District located in the Beskid Żywiecki Mountains in years 2002−2004. Habitats were investigated with regard to the forest types, age classes of the main tree species, canopy closure and altitude. We established 28 linear transects of the total length of 221 km. Data regarding Capercaillie occurrence (n=141) i.e., bird observations, tracks, feathers and droppings were collected twice during spring, summer, autumn and winter. Average index of Capercaillie density based only on birds seen amounted to 0.055/km of the transect and was the highest during spring (0,090/km). Availability and usage by Capercaillie, as well as preference index were calculated for distinguished habitat groups. As shown by Bailey's test, mountain mixed coniferous forest and mountain coniferous forest sites were preferred by Caperacillie, while mountain deciduous forest was avoided. The birds preferred spruce and beech stands of age ranging from 80 to 120 years. Moreover, stands with open and broken canopy and habitats located 800−1200 m a.s.l. turned to be highly preferred by Capercaillie. The obtained results were analyzed in relation to potential food resources, predator pressure and human disturbance. The following forest management measures in mountain refuges of Capercaillie were suggested: (1) maintaining open or broken canopy closure of stands, (2) policyclic timber harvesting system with a long period of regeneration, (3) patchy distribution of understory vegetation with cover below 50% of area, (4) maintaining in the ground flora at least 30% cover of bilberry, and (5) leaving seed trees and old−growth forest patches in clear−cuts as well as promotion of natural regeneration. This activities together with control of predation and reduction of human pressure allows to protect Capercaillie population in the Beskid Żywiecki Mountains.

‘Śnieżyczki’ nature reserve (E Poland) is characterised by forest ecosystems only, represented by the Mazovian variety of the subcontinent lime−oak−hornbeam forest Tilio cordatae−Carpinetum betuli and stachys lime−oak−hornbeam forest Tilio cordatae−Carpinetum betuli stachyetosum – a rarity on the regional scale – which represents the wettest and the most fertile kind of lime−oak−hornbeam forests, and whose species composition and structure is similar to those of riparian forests. The vascular flora of the reserve includes 119 species. The rich locality of Galanthus nivalis, situated in the forest complex of Sokołów Podlaski Forest District – which is the most north−eastward point of its natural range – is a flora curiosity.

Opis:
Changes in the herbaceous layer (vascular plants), taking place between 1959 and 2016 on the permanent study plot in the compartment 319 of the Strict Reserve in the Białowieża National Park are presented. Zaręba [1972] presented phytosociological research carried out in 1959 on the 1.2 ha plot. The author established 10 relevés (size between 100 and 400 m2), in which in total 91 different species of vascular plants were noted. In 2016, the similar study was conducted, using slightly modified methods (the inventory of plants involved the total area of the study plot). The comparison of data recorded during both investigations revealed that the total number of plant species declined from the initial 91 to current 83. During the ca. 60−year long period, 43 plant species disappeared completely and were replaced by 35 new species. In the declining group, almost the half (20) were species important from the point of view of nature conservation, including four Red List species (Arnica montana, Goodyera repens, Lathyrus laevigatus, Trolius europaeus), 10 plant species protected by law, and several other precious species related to rare and declining woodland community types. The obtained results confirm the findings of other authors describing unfavourable changes in the flora of the Białowieża Forest during the past several tens of years. The floristic richness is an important part of the overall biodiversity of Białowieża Forest. It appears that strict protection does not secure the maintenance of this key component. Thus, an attempt to preserve diverse values of Białowieża Forest on a sustainable basis should, first of all, look for a proper balance between strict and active protection. The later can (and should) be integrated within the multifunctional forest management, conducted on the prevailing area of the Białowieża Forest.

Opis:
The paper concerns forest populations of lady's slipper orchid (Cypripedium calceolus L.). The study sites were located in localities with the most numerous populations of Cypripedium calceolus L. in managed forests in Poland. The field studies were conducted in 2012 according to Natura 2000 sites protocols. The aim of studies was the determination of population structure of lady's slipper orchid, especially in indexes reflected number of flowering and fruit plants. The relations between above factors and environmental conditions expressed by ecological indicator values, cover of vegetation layers, species richness, stand age, and intensity of thinning were studies. The obtained results confirmed negative influence of understorey layer and positive influence of density of tree layer on the development of studied orchid populations. The increase in thinning intensity has not significant influence on protection status of Cypripedium calceolus.

This paper presents a study on a population of Pulsatilla patens conducted in 2012 in the Myszyniec Forest District in Natura 2000 area ‘Myszynieckie Bory Sasankowe’ in the Kurpie forest (NE Poland). The purpose of the study was to determine the population structure of Pulsatilla patens, especially with regard to abundance, density, and percentage of generative plants in the total population. Correlations were examined between these population features and selected environmental characteristics including ecological indicator values, community layer coverage, number of species group. For the evaluation of the linear relationship between the variables, Spearman's correlation coefficient was used. The research confirmed a significant effect of light availability, clear cuttings areas on all mean values of such indicators of plants as number of flowers, number of plants, share of vegetative and generative plants.
