“…Dynamic tendencies in the flora of railway areas are manifested mostly in overregional linear migration of plants whose diaspores were transported with trains (Jehlik & Heyny, 1974;Kowarik & Tietz, 1986;Jehlik, 1981Jehlik, , 1986Jehlik, and 1995Brandes & Oppermann, 1995;Tikka et al, 2001;Hansen & Clevenger, 2005). The consequences of migrations along railways (Kopecky, 1971;Brandes & Oppermann, 1995), were presented in a few papers of German authors (e.g.…”

Apart from roads, railways are one of the principal means of transportation. The specificity of rail transportation causes some environmental problems. The study presents a review of the major environmental problems connected with railway transportation. The construction of railway tracks and properties of used materials, as well as the maintenance of railway infrastructure are responsible for the specific habitat condition with alkaline soil reaction and varying but rather high levels of nutrients, which favour plant encroachment and growth. The results of investigations described in this study show clearly that railway transportation causes typical organic and inorganic contamination. Among the most important railway pollutants are polycyclic aromatic hydrocarbons, heavy metals, and to some extent, polychlorinated biphenyls. The study also presents some information about the progress of floristic studies in operating and abandoned railway lines. In addition some trends in the transformation of the flora in abandoned railway areas are discussed: the retreat of alien species with a short life cycle, the encroachment of native perennial plants and an increase in the number of trees.

“…Transportation corridors offer a variety of substrates, soil-types and nutrient levels on a small scale, and in agricultural regions, urban areas, and other highly modified landscapes, road and railroad verges may be the only semi-natural habitat that remain (Thomas et al 2002, Forman et al 2003, Huijser and Clevenger 2006. Moreover, roads and railroads stretch along the landscape, with a potential to connect remnant habitat patches (Vermeulen 1994, Eversham and Telfer 1994, Tikka et al 2001, Viles and Rosier 2001, Thomas et al 2002, Hopwood 2008. As being present in most landscapes, the green network formed by semi-natural strips along roads and railroads has been labelled "a centerpiece of conservation" (Forman et al 2003).…”

Road and railroad verges may contribute to nature conservation by providing habitat for many species, but due to limited resources, there is a need to select the most important road and railroad stretches for adapted management. We explore the responsibility species concept as a tool for the Swedish Transport Administration to make this selection. We propose lists of candidate responsibility species based on relative abundance of conservation priority species in the vicinity of roads and railroads, respectively. Abundance data were derived from crowd-sourced species observations. Species with ≥20% of observations in infrastructure habitats were included as candidate responsibility species. For roads 32 species were included in the list, for railroads seven species, with an overlap of three species between the lists. We analyzed habitat and management requirements of the listed species to try identifying functional groups. Most of the species require open or semi-open habitats, mainly dry grassland or heathland on sandy or limy soil, un-sprayed crop fields, or solitary trees. Host plants or substrates include broom (genus Genista), patches of bare soil, and sun exposed wood. Conservation actions prescribed for the species include, e.g., late or irregular mowing, removal of the field layer, planting of host species, protecting and providing particular substrates, and special protection of certain sites. We argue that road and railroad managers are particularly well suited to conduct most of these actions. We consider the responsibility species concept to be a useful tool for transportation agencies to set priorities for adapted verge management, and the current method to be effective in identifying a first list of candidate species. We discuss the possibility of also identifying responsibility habitats or general management measures based on the results.

“…The railway was surrounded by deciduous forest, wet meadows and willow thickets. Railway embankments are often considered as good migration corridors for thermophilic plants [4] such as members of the genus Pilosella. We observed dozens of individuals of P. cymosa, but only several specimens of P. bauhinii.…”

“…Many species, moreover, successfully colonize man-made habitats, for example, railways and roadsides [3]. Especially interesting is their occurrence on railways, because these linear landscape elements are considered as migration avenues for many alien as well as rare and endangered species [4][5][6]. In Poland, species of Pilosella are often locally rare, and some are considered endangered [7][8][9][10].…”

We provide information about two species, Pilosella bauhinii and P. cymosa subsp. vaillantii (Asteraceae), from new localities in north-central Poland (ATPOL DC18). All individuals of both species grew on a railway embankment in Górzno-Lidzbark Landscape Park. The ecological preferences for P. cymosa and P. bauhinii estimated according to average Ellenberg values nearly coincided with the original description of Ellenberg. We also sequenced the barcode marker, plastid trnH-psbA intergenic spacer, for two individuals of P. bauhinii, three specimens of P. cymosa subsp. vaillantii, and additionally two individuals of P. officinarum L. and one H. murorum L. growing in close proximity. A pairwise comparison of trnH-psbA sequences showed that each species has a unique haplotype. Taking into account their morphological coherence, it is possible that both P. bauhinii and P. cymosa have not hybridized yet, at least locally, with the more abundant species (e.g., P. officinarum). A search for reference sequences did not provide additional information because of the low quality of the reference database for this group in GenBank. Only 14 sequences of trnH-psbA were available with some apparently being misidentified or of low quality. None were identical to sequences of P. cymosa subsp. vaillantii and P. bauhinii found in this study.
