Vascular plants of the Kozi Rynek Nature SUMMARY The Kozi Rynek Nature Reserve is located in the southern part of the Augustów Forest (NE Poland). The reserve protects 146.63 ha of the forests which have retained their primeval features. The majority of the reserve area is covered by swampy black alder forests of various types. Mixed or broadleaf forests of hemiboreal character (dominated by spruce, lime, oak and other deciduous tree species) have developed on mineral soils surrounding the peat-covered depression (and on mineral islands within it). Purely coniferous forests are scarce and represented by small patches of Sphagnum-dominated spruce forests on peat and mesic spruce forests on mineral sandy soils. Until now the knowledge about the flora of the reserve has been very limited. A survey of the vascular plants of the reserve was conducted between July 2009 and September 2010. The flora of the reserve contained 259 species, including 172 dicotyledons, 70 monocotyledons, 15 pteridophytes, and two representatives of gymnospermns. Twenty-four species of endangered plants in Poland or protected by national law were found, including five species listed in the Polish Red Data Book: Carex disperma, C. globularis, C. loliacea, Epipogium aphyllum and Viola epipsila. Alien plant species constituted only 2.3% of the flora of the reserve. There were also 65 species associated with old-growth forests, which constituted 42% of the species considered to be "the old-growth forest indicators" in Poland. A smaller number of these species in the reserve than in the corresponding fragment of the Białowieża National Park may be explained by a significant difference between the share of mineral soils in relation to wetlands in both areas, the relative isolation of the Kozi Rynek Nature Reserve from other forests of natural character and the surroundings of the reserve that are dominated by pine stands transformed partially by human activity. At present, the vegetation of the reserve is not subjected to significant anthropogenic influence. The most important threat is the removal of spruce trees attacked by bark beetle. In order to protect the forests with the most primeval features it would be advisable to establish the strict protection regime in the old-growth forest areas. There is a necessity of monitoring the hydrological conditions, altered by drainage performed south from the reserve, and elimination of alien woody species.
Importance of substitute sites in the maintenance SUMMARY
In the years 1985 - 1989 five substitute sites of Carlina
onopordifolia were established: first two localities in Mstów on the Kraków
- Częstochowa Upland (Góra Wał and glade Golizna), the further two stands on
the Miechów Upland (in Racławice and in nature reserve "D±bie" near Klonów) and
the fifth one in Skowronno Dolne on the Pińczów Hummock. Genetic material was
collected from nature reserve "Wały". The localities in Mstów were created in
effect of cultivation of seedlings, the remaining ones were formed by sowing
seeds directly into xerothermic grasslands of the Inuletum ensifoliae association.
Only in four sites (two in Mstów, one in Racławice and one in Skowronno) introduced
populations yielded flowering plants in the years 2000 - 2010, guaranteeing
their regeneration, however in the reserve "D±bie" no flowering plants were
observed since 1987.
Occurence of common maple Acer campestre L. SUMMARY The "Ostrów Panieński" and the "Łęgi na Ostrowiu Panieńskim" nature reserves, situated in Jamy Forest District near Chełmno (Kujavian-Pomeranian Province), protect rare forest association in Poland - elm-ash riparian forest Ficario - Ulmetum minoris, which is only slightly transformed by forest management activities and which represents highly natural riparian association. It is the largest natural site of common maple Acer campestre in Chełmno Region. The main aim of the study was to analyze structural characteristic of common maple and its natural regeneration in both nature reserves. We found that Acer campestre is present in all forest association layers. In the "Ostrów Panieński" nature reserve 720 trees of common maple were found whereas in the "Łęgi na Ostrowiu Panieńskim" nature reserve 262 trees of common maple were found. Among the common maple trees found in both nature reserves some had diameters at breast height that exceed 200 cm. Moreover, we found quite frequent natural regeneration of common maple - mean density of natural regeneration in the "Ostrów Panieński" nature reserve was ca. 4000 trees ha-1, whereas in the "Łęgi na Ostrowiu Panieńskim" the mean density of common maple seedlings was ca. 2300 trees ha-1. The results of the study show that in both nature reserves the common maple populations are stable and not endangered.
SUMMARY
The study investigates species composition of necrophilous beetle
assemblages in forest areas of the Białowieża
Forest. Sampling plots
were established in Forest Districts of Białowieża, Browsk and Hajnówka and the
Białowieża National Park. These areas represented
13 forest habitat types encountered in the Polish part of the Białowieża Forest.
Each forest habitat type was represented by 12 sampling plots established in
old forests. Additionally, 9 research plots were established in younger stage
tree stands. Five Barber traps were set within each research area. As a result,
from June to October 1999, 5594 necrophilous beetles were collected, which
represented 32 species. Sphaeritidae family was represented by the only
species known from Poland,
namely Sphaerites glabratus (FABRICIUS, 1792), Histeridae - by 6
species, Leiodidae - by 15 species, and Silphidae - by 10
species. Most numerous species among the collected individuals were the
following: Silpha carinata HERBST, 1783, Nicrophorus vespilloides HERBST,
1783, Silpha obscura (LINNAEUS, 1758), Phosphuga atrata (LINNAEUS,
1758), Catops picipes (FABRICIUS, 1787), C. nigricans (SPENCE,
1815), Apocatops nigrita (ERICHSON, 1837), Oiceoptoma thoracicum (LINNAEUS,
1758) and Margarinotus striola succicola (THOMSON, 1862).
SUMMARY
Prior to this study only 28 species of Syrphidae were known from
the Ojców National Park (ONP). These data were
gathered mainly by WAGA (1857) and SZNABL (1881) in the 19th
century. During the studies in 1986 - 2008 almost 1400 individuals of
hoverflies from 169 species were collected. Presence of five previously
recorded species has not been confirmed: Eristalis oestracea, Cheilosia
soror, Chrysogaster basalis, Pipizella virens and Sphaerophoria
rueppelli. In result 174 species are included in the list of Syrphidae in
the ONP, which constitutes 43% of Polish fauna.
Occurrence of small mammals in the Kwiatówka Nature Reserve SUMMARY In the years 2005 - 2007 the research on small mammals was carried out in the Kwiatówka Nature Reserve (the Małopolskie Province). The research was performed with three sampling methods: catching of small mammals with snap traps and pitfalls, and collecting of pellets from Towny Owls nesting in the Reserve. There were 16 species of small mammals found that represented five families - Muridae, Soricidae, Myoxidae, Talpidae and Vespertilionidae. Three species - Microtus arvalis, M. agrestis and Apodemus flavicollis were represented in large numbers, what reflected pray preferences of Towny Owls (the research on pellets). Seven species are under strict legal protection, including Glis glis listed in the Polish Red Data Book of Animals. This type of teriological research was carried out for the first time in the Kwiatkówka Nature Reserve. The use of three sampling methods provided reliable research results.
Short floristic, faunistic and micobiotic notes
New locality of rusty click beetle Elater ferrugineus SUMMARY New locality of two saproxylic beetle species (Coleoptera) in the Wielkopolsko-Kujawska Lowland is given. For both species locality mentioned in this paper is the fourth one currently known for the Wielkopolsko-Kujawska Lowland. Both species are strictly connected mainly to deciduous natural forests, but also to the mixed ones. They are regarded as a relict species of these kind of forest ecosystems. Due to their environmental requirements these species are threatened because of currently dominating forest management in Poland. Practical recommendations for ensuring continuous existence of their populations in the "Postomia Valley" reserve are formulated. These recommendations can also be applied to any other natural forests, where populations of rusty click beetle, scarce fungus weevil or any other saproxylic beetle species exist.
Occurrence of the spirlin Alburnoides SUMMARY In the present work some new data regarding the distribution of a rare cyprinid fish, spirlin Alburnoides bipunctatus, in the Nida River are presented. The spirlin, which is considered an endangered species (EN), was recorded on two localities in the lower course of the Nida River: in Pasturka near Pińczów and in Wi¶lica (twice). All the specimens were captured during the seining performed at night. The species was absent from the seining performed at daytime, as well as from the samples from concurrent electrofishing. It is the first record of the spirlin in the Nida River since the end of the 1960s.
