The main aim of this study is to present the role of anthropogenic habitats created by the remnants of old iron ore mining activities in preserving the ancient woodland plant species (AWS). The studies, which took place in 2010–2015, covered 30 former post-mining fields in the northern foreland of the Świętokrzyskie Mountains (SE Poland). Each field contains the remnants of old iron ore mining – gob piles and the areas not transformed by mining, which surround the heaps. Within each post-mining fields, two lists (on gob piles and in their surroundings) covering the AWS were prepared. Additionally, two substrate samples were taken – one from the randomly selected gob pile, and one from the non-transformed site. The relationships between the numbers of AWS and selected environmental variables were analysed by statistical methods. It was found that the difference in the number of AWS characteristic of the Querco-Fagetea class between gob piles and their surroundings is significant. The conducted analyses indicated that this difference is not resulting from the difference in the areas between gob piles and their surroundings but from the pH of the substrate. The numbers of the mesophilous AWS in gob piles are not uniform and range from 3 to 37 and are correlated with the age of gob piles, the pH values and the depth of the iron ore deposits. At present, the remnants of old ore mining – gob piles constitute the sole habitat islands for the ancient mesophilous deciduous woodland species within the northern foreland of the Świętokrzyskie Mts.

Typhetum laxmannii (Ubrizsy 1961) Nedelcu 1968 is a plant association new to Poland, built by an expansive kenophyte - Typha laxmannii Lepech. This paper presents the general distribution of both, the species and the association, paying particular attention to the area of Europe and Poland where, in recent years, many new locations as well as an increasing participation in vegetation cover have been observed. The habitat preferences of Typhetum laxmannii, the floristic composition of the association and its geographical differentiation within the occupied area are described. The current distribution of the association in Poland is presented on the cartogram map 10x10 km and possible expansion routes are suggested.

Malaxis monophyllos is a rare orchid with a fragmented boreal-montane distribution in Europe where it is associated with both natural swampy and anthropogenic habitats. We employed extensive sampling of M. monophyllos populations from different habitat types, over its whole European geographic range, to examine its genetic diversity patterns and phylogeographic structure using amplified fragment length polymorphisms (AFLPs). Our results revealed the relatively low genetic diversity of M. monophyllos, with the effect of small population sizes and inbreeding as the driving forces operating within the European part of its range. The statistically highest values of genetic diversity were found in populations from the boreal region (average: percentage of polymorphic loci PPL₃ = 21.6%, Nei's gene diversity Hj₃ = 0.144, the rarity index DW₃ = 1.34), while populations from mountainous regions were characterised by a reduced level of genetic diversity (e.g. an average for Alpine populations: PPL₃ = 18.1%, Hj₃ = 0.121, DW₃ = 0.84) in comparison to boreal ones. Our results revealed that the newly established anthropogenic populations in the Polish uplands were probably founded from numerous external sources and should be considered a significant source of the species' genetic diversity. We also confirmed the low genetic differentiation among M. monophyllos populations (FST = 0.074), with the lack of distinguishable genetic clusters, that supports results about the multidirectional gene flow between M. monophyllos populations in Europe, and directed conservation efforts on conserving all suitable for this species habitats.

Scleroderma septentrionale Jeppson was fi rst discovered in Central Europe in the Puszcza Kampinoska primeval forest (Central Poland) over 40 years ago. We found two new inland localities of this rare species in southern Poland: on natural inland sand dunes of post-glacial origin (Pustynia Błędowska) and at an anthropogenic site on sandy soil polluted by heavy metals (Olkusz, in the vicinity of the Bolesław Mine and Smelter). The basidiocarps occurred under willow and birch or pine and birch. The new localities are approximately midway between two previously known inland stands in Central Europe (Puszcza Kampinoska forest and the Zahorie region in Slovakia).

The Giant Horsetail (Equisetum telmateia) is the only representative of Equisetum genus included in the list of strictly protected species. In Central and Western Europe the species is found in communities belonging to alliances: Alno-Padion and Calthion. With progressing destruction of these biotopes, one can observe the phenomenon of this species moving to the habitats extremely anthropogenic in character. Frequent and intensive observations of this phenomenon were conducted in the Jasło - Krosno Dale area in southern Poland in three anthropogenic localities. In these localities three interesting, irregular Equisetum telmateia morphotypes were found: fo. serotinum subfo. proliferum, fo. spiralis and a morphotype with branched shoot. The phenomenon of morphological plasticity of sporophytes is thought to be connected with the action of genes, which regulate the identity of developing plant organs and their distribution. These genes perform a superior part in relation to the system of growth regulators.

Along a 4.8 km long stretch of the ecological corridor of the lêza river, 175 patches dominated by Helianthus tuberosus s.l. were found. Among them, about two-thirds are not bigger than 4 m2, but many of the other patches cover areas of several hundred square meters to about 1300 m2. The effect of the H. tuberosus stands on the vegetation of anthropogenic habitats was studied at two sites: one post-agricultural and one post-industrial. At both sites, a system of transects with study plots was laid out. The transects began outside of the H. tuberosus stands (stage A) and penetrated their inside comprising three distinguished stages (B to D) of increasingly higher and denser thickets of sunflower. No significant differences between habitats were found. At both sites, there was a strong decrease in the number and biomass of co-occurring species only in the older stages (C and D) of thicket development, but not at the edges (B), where short H. tuberosus individuals strongly compete with other species.

The article presents the preliminary results of research on changes in the abundance and population density of Epipactis helleborine carried out during the vegetation seasons of 2010 and 2011. The spatial distribution of ramets was analyzed in terms of population changes. The population studied was located in an anthropogenic habitat near the village of Guszczewina on the outskirts of the Białowieża Forest. The results of the study suggest that vegetative multiplication was dominant in the population. An attempt is made at finding the cause and extent of this phenomenon.

Bożodrzew gruczołkowaty rośnie i rozprzestrzenia się we Wrocławiu, daleko poza obszarem swojego naturalnego zasięgu. W pracy zbadano jego stan odżywienia w warunkach miejskich Wrocławia. Stwierdzono zróżnicowane pH, które dla wierzchniej warstwy gleby wynosiło od 5,4 do 7,8, a w warstwie niższej (20,1-40 cm) kształtowało się od 5,5 do 7,9. Gleby na stanowiskach z bożodrzewem były zasobne w makroskładniki. Średnia zawartość N-NO3 wynosiła od 138,5 do 160,0 mg N-NO3∙dm-3, fosforu - od 117 do 603 mg P∙dm-3 w poziomie górnym i od 155 do 508 mg P∙dm-3 warstwie niższej, potasu w poziomie pierwszym - 140 do 430, a mg K∙dm-3 w warstwie niższej od 150 do 420 mg K∙dm-3, magnezu - od 70 do 145 mg Mg∙dm-3 w warstwie górnej i od 45 do 190 mg Mg∙dm-3 w warstwie niższej, wapnia - w warstwie górnej od 1000 do 3600, mg Ca∙dm-3, a w poziomie niższym od 750 do 3800 mg Ca∙dm-3. Zawartość makroskładników w liściach bożodrzewu gruczołkowatego była podobna do ich zawartości u innych gatunków drzew, np. klonu pospolitego i jesionu wyniosłego. Jedynie magnez u bożodrzewu w liściach występował w dużych ilościach - od 0,91% do 2,50%.

Tree of heaven grows and spreads in Wroclaw, i.e. far from its natural zone of occurrence. The aim of this study was to assess the nutritional status of tree of heaven under urban conditions of Wrocław. The investigation proved diversified pH of soils, ranging in the surface layer from 5.4 to 7.8 and in the lower layer (20.1-40 cm) its value was between 5.5 to 7.9. The soils, this species is growing on, are rich in macroelements. Average content of N-NO3 amounted from 138 to 160 mg N-NO3∙dm-3; phosphorus - from 117 to 603 mg P∙dm-3 in upper level and from 155 to 508 mg P∙dm-3 in lower layer; potassium in the first level - 140 to 43 mg K∙dm-3, and in lower layer from 150 to 420 mg K∙dm-3; magnesium from 70 to 145 mg Mg∙dm-3 in upper layer and from 45 to 190 mg Mg∙dm-3 in the lower one; calcium - in upper layer from 1000 to 3600 mg Ca∙dm-3 and in the lower layer from 750 to 3800 mg Ca∙dm-3. The content of macroelements in tree of heaven leaves was similar to the content of these elements in other species of trees, e.g. Norway maple or common ash. Magnesium, however, reached considerable contents ranging from 0.91% to 2.50%.
