Deptford pink Dianthus armeria L. is a representative of Caryophyllaceae family. It is plant species that is strictly protected since 2014. In the local Red List for the Silesian Province it was considered an endangered species. During 2023-2024 fieldwork was done that aimed to update the list of the localities of this species in the Cieszyn Foothills region. The locality was marked on the map using methodological assumptions of Atlas of Distribution of Vascular Plants in Poland. The density of population was counted or estimated. As a result of the field studies in the study area 9 localities (a total of 17 local populations) of Dianthus armeria were found in grassland, meadow, fringe and ruderal communities. Totally 8 localities were new to this area. Only localities from Tuł Mt has been known earlier. There were also the highest abundance of population, estimated at 600-700 individuals but population contain several small populations that amounting from tens to several hundreds of plants. Two populations are in Cisownica village and they occupy slopes of two local mountains: Kopieniec Mt (475 m a.s.l.) and Malcowa Mt (510 m a.s.l.). In Cieszyn population grows close to the nature reserve “Kopce”, and ecological use are “Łąki na kopcach”. In Leszna Górna village populations occupy xerothermic grasslands. The other situation is Górki Wielkie where the species grows in ruderal habitats: levees along Brennica river and in the vicinity of market. The other human-made habitats which were grown by Dianthus armeria were found in Puńców. These ones were abandoned quarry of dolomites and the vicinity of sports field but close to the fring of oak-hornbeam forest. In general, the population in the Cieszyn Foothills, size ranged from a few individuals to approximately several hundred. The lack of accurate data from previous years does not allow to assess the dynamics of the distribution and abundance of this species. Based on the general trends of Dianthus armeria in Poland, the population status appears to be satis-factory.

The current study was undertaken to determine long-term population trends (33 years) of ungulate species in the Waterberg National Park (WNP), Namibia, using aerial and waterhole counts of ungulates during the years 1980-2013.We tried to establish how rainfall influences the multi-species population dynamics. During this period sixteen ungulates species were recorded. Among these, eight have shown an increase in numbers during the years 1984-2013, six other decreased, and populations of two other species remained stable. Roan and sable antelope, kudu and warthog were fairly common (with 5-12% of all ungulates recorded). White rhino, black rhino, giraffe, and gemsbok were classified as uncommon (together 11.9%), whilst the remaining eight species were rare (together 1.9%). The eland population showed a weak positive relationship with the annual average rainfall between the years 1981-2013, whereas population sizes of kudu, sable, gemsbok and roan showed a weak negative relationship with the amount of rain. No relationship was detected in giraffe, buffalo and hartebeest populations. We conclude that, irrespective of water supplementation, ungulate densities are to a large extent controlled by rainfall.

Publikacja przedstawia wyniki badań florystycznych przeprowadzonych na poboczach dróg powiatowych w granicach gminy Śliwice. Flora przydroży tego regionu liczy 185 gatunków roślin naczyniowych. Współczynnik różnorodności gatunkowej pojedynczych płatów mieści się w granicach 2- 2,5 i jest niewiele mniejszy niż na łąkach. Zgromadzony materiał obejmuje łącznie 186 gatunków roślin naczyniowych - więcej niż na łąkach tego obszaru. Najliczniej występujące gatunki to: Festuca rubra, Arrheriatherum elatius, Elymus repens i Dactylis glomerata. Poza taksonami pospolitymi na przydrożach występuje szereg gatunków objętych ochroną gatunkową. Należą do nich: Frangula alnus, Helichrysum arenarium, Ononis spinosa, Arctosta-phylos uva-ursi, Convallaria majalis oraz Epipactis helleborine, Botrichium lunaria i Botrichium matricariifolium. Wysoka lesistość i ekstensywne rolnictwo w Borach Tucholskich sprzyjają wysokiej wartości przyrodniczej regionu. Przydroża są specyficznymi, odrębnymi siedliskami w leśnym krajobrazie. Z uwagi na bogatą florę, duży zasób rzadkich i chronionych gatunków, jak również dzięki wysokiej bioróżnorodności każdego badanego płatu, przydroża stają się istotnym elementem lokalnej różnorodności gatunkowej.

The paper presents the results of the floristic research carried out on the roadside verges of the county roads within the borders of Śliwice commune. Roadside verges flora of this area consists of 185 species of vascular plants - more than in the neighbouring biocenoses. The species diversity index ranges from 2 to 2.5 - not much lower than in the meadows. Among the most frequent species to be found: Festuca ruhra, Achillea millefolium, Arrhenatherum elatius, Dactylis glomerata, Artemisia vulgaris, Lolium perenne and Elynius repens. Many rare and protected taxa were also present: Frangula alnus, Helichnjsum arenarium, Ononis spinosa, Arclostaphylos uva-ursi, Convallaria majalis, Epipactis helleborine, Botrichium lunaria and Botrichium matricariifolium. Intensive forestation and extensive agriculture in the Tuchola Pinewoods contribute to high conservation value of the region. The roadside verges have become specific and unique habitats in the forest landscape. Due to rich flora, large stock of rare and protected species, in addition to high diversity of each investigated plot, the roadside verges have turned into a significant element of the local biodiversity.
