Preliminary ecology research on Epipactis atrorubens (Hoffm.) Besser on the Słowińskie Coast (Northern Poland)

The research covered three stands of Epipactis atrorubens on the Słowińskie Coast (Rowy, Wicko Morskie and Jarosławiec). The plants in blossom were characterized on the basis of seven individual characteristics: height, the number of leaves, the number of flowers per inflorescence, the length and width of the largest leaf and stipule. Statistically significant differences were found in the studied populations between the height of the plant and the width of the largest leaf, the number of flowers per inflorescence and the inflorescence length up to the bract, as well as between the number of flowers per inflorescence and the inflorescence length up to the bract. The populations of E. atrorubens on the Słowińskie Coast cover the mineral soil with the dominance of medium- and fine sand fractions. Those soils are loose with very low water capacity and good permeability. The organic matter content varied from 0.4 to 0.8%. The soil reaction is low acid or close to alkaline. The analyzed soil samples were characterized by very low content of exchangeable Al3+ ions, which results from relatively high pH levels. The soil salinity was low and the average content of NaCl was between 0.146 and 0.181 g·dm-3

The distribution of Chrysanthemum segetum L. (Asteraceae) in Poland.

The distribution of Chrysanthemum segetum L. in Poland, based on a field research, herbarium materials, literature and unpublished data, is described with a list of localities. Altogether, 352 localities (210 ATPOL squares) for this species have been identified. Most localites are concentrated in North and West parts of Poland..

Dendroflora of parks and gardens on the Pomeranian Cistercian Trail

Ordo Cisterciensis was set up on March 21, 1098 in France. The Benedectine monks were the founders who aimed at linking the principles of Benedict of Nursia with ascetism and the eremitical ideal of living. The Cistercians came to Pomerania in the first half of the 12th century. Their presence resulted in the evolution of science, culture, medicine, crafts and agriculture. Several smaller objects such as parish churches, chapels, manor houses, parks, gardens and farmhouses bring back memories of brilliance and affluence of Cistercian monasteries in Gdańsk Oliwa, Kartuzy, Starzyński Dwór, Żarnowiec, Puck, Bukowo Morskie, Iwięcino, Skibno, Słowino and Koszalin-Góra Chełmska. In 1990 the Council of Europe undertook a decision to create a tourist path based upon ‘the foot steps of the Cistercian monks’ under the auspices of the international programme ‘European Cultural Routes’. Field studies that were undertaken in 2017-2019 included Postcysterian objects mentioned above. The study aims at presenting geographical–historical status, range groups and life forms of the chosen parks and gardens. The dendroflora of parks and gardens comprises 237 taxa. They belong to 109 genera and 48 families. A total of nine species covered by legal protection were reported: Pinus cembra, Rhododendron luteum, Rosa gallica, Sorbus torminalis, Sorbus intermedia, Hippophae rhamnoides, Lonicera periclymenum, Pinus mugo and Taxus baccata. Among rare species present we should mention: Taxodium distichum, Acer campestre, Ginkgo biloba, Metasequoia glyptostroboides, Liriodendron tulipifera and Wollemia nobilis

Ancient woodland indicator plant species in the parks and gardens of the Pomeranian Cistercian Trail

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

Spergulo-Chrysanthemetum segeti (Br.-Bl. et de Leeuw 1936) R. Tx. 1937 in the Drawsko Lakeland (Western Pomerania)

The species richness and structure of Spergulo-Chrysanthemetum segeti have been assessed on the basis of 25 phytosociological relevés made by the Braun-Blanquet method in the Drawsko Lakeland (Poland). Two variants have been distinguished, Spergulo-Chrysanthemetum segeti chamomilletosum typicum and Spergulo-Chrysanthemetum segeti chamomilletosum with Plantago intermedia. The paper presents the distribution and analytical characteristics of this subatlantic association against the background of habitat conditions

Needles and bark of Picea abies (L.) H. Karst and Picea omorika (Pancic) Purk. as bioindicators of environmental quality

The paper presents the results of the research on the accumulation of nutrients and heavy metals in needles and bark of Picea abies and Picea omorika. In this research, the age of the needles and the content of the examined components in the soil were taken into account. The research was conducted within the area of the forest at the University botanic garden in Košice (Slovakia). The little acidification of the soil that was found under the spruce crowns slightly changed with the depth (0.0–0.2 m, 0.2–0.4 m, 0.4–0.6 m). Under the stand of P. abies, a lower content of organic matter was demonstrated, than under the trees of P. omorika. The tested soil samples were low in nitrogen, phosphorus and calcium, and sufficiently rich in potassium and magnesium. The spruce needles were dominated by macroelements, and their concentrations varied depending on age and species. Both P. abies and P. omorika needles were acidic, with 1-year-old needles showing higher acidity. Low nitrogen content in the needles of the studied spruce was found, and the N:P ratio did not exceed 3.5. Statistically significant differences were found in the content of N, K, Ca, Zn, Mn, Fe, Ni, Cu and Cd in 1-year-old needles and pH, N, P, Ca, Zn, Mn, Fe, Ni, Cu and Cd in 2-yearold needles of spruces. The results also indicate that the bark of the studied spruce is acidic, with pH values of 4.70 (P. abies) and 4.15 (P. omorika). The P. abies bark accumulates higher amounts of Mg, Ca, Ni, Cu and Mn, and the P. omorika bark accumulates more N, P, K, Zn, Fe and Cd. The research indicates that both spruce species barks are suitable for comparative studies on bioindication of environment quality
