Objective: Main purpose of this study is to identify the ruderal plant species which spontaneously grows on the wall and roof surfaces in urban and suburban areas due to their limited ecological needs and to contribute to the creating of the sustainable green areas in urban environments by understanding the parameters that ruderals depend on while they require little maintenance and irrigation support if not no. Material and Methods: The main material of this study is the ruderal plants which were collected from totally 60 walls and 36 roof surfaces within six districts of Trabzon city-Akçaabat, Arsin, Çaykara, Of, Ortahisar and Yomra in Turkey. From these 96 habitats, 1540 plants samples form the walls and 448 plant samples from the roofs were collected. All the plant samples collected from the research area were identified in the herbarium of the faculty of forestry in Karadeniz Technical University. Apart from this, parametres affecting coverage rate of common species on three different habitats were analysed. Results: It was found that 448 samples from the roof surfaces distributed into 61 species while 1540 samples from the walls distributed into 196 species. Plus, according to the analyses, 28 species were found on all three different habitats. As a result of the observations, measurements and analyses, it is clear from the study that coverage rate of the plant species depends on anthropogenic interaction, daylight period and depth of the media but there is no relation with the number of the species on the surfaces. Conclusion: Ruderal plants are definitely important to study on, if the world wants the term sustainability to find its real meaning as they require nearly nothing to grow in hard conditions. In urban life, maintenance is getting more and more expensive for green areas in urban life and this makes it difficult for them to survive especially when cities have limited budget on this, which has often occurred all over the world recently. There is no doubt that ruderal plants offer a great opportunity for modern era urban areas with their limited needs to grow in hard conditions. Furthermore, when thinking about the fact a serious amount of the ruderal plants detected on all three basic habitats has a great landscape plant characteristics, the approaches to their usage in urban areas are really critical.

Ruderal flora develops in urban and rural settlements and other areas with pronounced direct or indirect human activity. During the three-year research (2018-2020) of the flora of ruderal habitats in the area of the city of Jagodina, 284 vascular plant species recorded, classified into 56 families and 184 genera. The families with the largest number of species are Asteraceae (46 sp.), Poaceae (29) and Fabaceae (24). These families are also represented with the largest number of species in the flora of Serbia. The genera with the largest number of species are Veronica and Trifolium. This paper presented a list of registered plant species.

RESUMEN: Damos cuenta de la rápida expansión de la compuesta Dittrichia graveolens por las carreteras del Pirineo aragonés occidental, especie de fenología otoñal que estaba ausente hasta el momento de su flora. Ligamos esta súbita aparición al uso primaveral del herbicida glifosato para el mantenimiento de las cunetas. ABSTRACT: Expansion of Dittrichia graveolens (L.) Greuter (Asteraceae) by the roads of the Pyrenees (Spain) and the use of glyphosate herbicide. We describe the rapid expansion of Dittrichia graveolens (Compositae) on the roads of Western Aragonese Pyre-nees. This species has an autumnal phenology and was absent at the time of the West Pyre-nean flora. This sudden appearance we believe that is due to the use of the herbicide glyphosate in the spring, for removing herbs of drainage ditches.

The article deals with ecological transformations in occupied and postwar Warsaw. The September campaign, the Warsaw Ghetto Uprising and the Warsaw Uprising had the greatest impact on these transformations, but bombings, fires and combat action also contributed to the degradation of the (natural) space. In just a few years, the urban tissue underwent enormous transformations. Wróbel-Bardzik defines the (post)war ruderal landscape with its two opposing phenomena of destruction and vital processes.
