Immovable objects of cultural heritage are inextricably linked to the place where they are located. The preservation of the object itself and its perception in the historical context guarantees the immutability of the protected area. Pyatigorsk historical and cultural heritage sites were used to assess the stability of their associated landscapes. The transformation of historical landscapes over time was established as a result of field research and analysis of the photo bank of data over a 125-year period. Landscape changes are associated with changes in vegetation during biological invasions, that is, they are the result of a combination of natural and anthropogenic factors. Platycladus orientalis (L.) Franco, Laburnum anagyroides Medik., Syringa vulgaris L. participate in the transformation of the landscape of the Lermontov grotto, and Robinia pseudoacacia L., Ailanthus altissima (Mill.) Swingle, and Parthenocissus quinquefolia (L.) Planch. participate in the transformation of the landscape of the Diana’s Grotto. All of them in previous years were introduced to the culture for use in landscaping Pyatigorsk. Their distribution and introduction to local cenoses began at the end of the XX century, after they entered the stage of naturalization. The listed invasive species have different geographical origins (Europe, Eas t Asia, North America) and belong to different life forms (coniferous tree, deciduous tree, deciduous shrub, deciduous liana). Platycladus orientalis (L.) Franco, Syringa vulgaris L., Ailanthus altissima (Mill.) Swingle are phytocenozotransformers, that is, they are dangerous not only for the landscapes of cultural heritage sites, but also for native plant communities. Robinia pseudoacacia L., Parthenocissus quinquefolia (L.) Planch. And Laburnum anagyroides Medik. are currently epectophytes, which does not exclude the possibility of their transition to agriophytes. The restoration of historical landscapes requires human intervention.

Asbestos is widely mined and used around the globe posing a great risk to environment and human health. The main objective of this study was to determine allelopathic potential of Robinia pseudoacacia L. and Ailanthus altissima (Mill.) Swingle growing on the asbestos deposits at abandoned mine ?Stragari? in central Serbia. The pH, content of carbon, nitrogen, calcium carbonate, available phosphorous and potassium, content of Fe, Ni, Cu, Zn, Pb, Mn, and phenolics were analyzed in the control asbestos (zones without vegetation cover) and plant rhizospheric asbestos. Allelopathic activity of plant species was assessed by ?rhizosphere soil method?, and Trifolium pratense L. and Medicago sativa L. were used as the indicator species. A. altissima showed higher allelopathic potential compared to R. pseudoacacia for T. pratense and M. sativa due to greater content of phenolics. Alleopathic activity of phenolics in rhizospheric asbestos was highly correlated with pH, content of carbon and nitrogen, available phosphate and potassium, and content of Ni, Cu, Zn, Pb and Mn. A. altissima increased phenolics content in rhizospheric asbestos inhibiting the plant growth. This woody plant in spite of high allelopathic potential is suitable for revegetation of distrurbed ecosystems because it initiates pedogenesis and affects the asbestos chemistry.

Native Woody Species

The process of invasion, naturalization, dispersion and invasive activity of non-native woody species in 5 regional floras, 5 urban floras and over 30 floras of the protected areas is discussed. It has been established that 182 non-native species out of 95 genera and 45 families are currently at different naturalization stages in the spontaneous flora of Ukraine. In terms of life-forms, they may be divided as follows: trees – 41%, shrubs – 35%, trees/shrubs – 15%, lianas – 9%. Most species spread both via seed dispersal and the vegetative way – 56%, using only seed dispersal – 42%, only the vegetative way – 2%. According to the preliminary rating of species-wise invasive activity, 71 species (40%) have naturalized completely, among them 20 invasive species, including 12 transformer species, 29 potentially invasive species, and 22 naturalized species which demonstrate no invasive tendencies. The initial stages of invasion of 111 species are as follows: introduction – 9%, survival – 36%, adaptation of the reproductive sphere – 28%, establishment, formative of local populations – 27%. In terms of dispersion, non-naturalized species are divided as follows: rare – 45%, local – 16%, sporadic – 6%, unique – 12%, spreading under control beyond collections and expositions in botanical gardens and arboretums – 21%. Twelve transformer species, the greatest threat to local diversity, are Acer negundo, Ailanthus altissima, Amorpha fruticosa, Bupleurum fruticosum, Elaeagnus angustifolia, E. rhamnoides, Fraxinus ornus, Parthenocissus quinquefolia, P. vitacea, Robinia pseudoacacia, Rhamnus alaternus, Salix × blanda and 8 invasive proper species: Berberis aquifolia, Colutea orientalis, Daphne laureola, Prunus cerasifera, P. serotina, Quercus ilex, Viburnum tinus, Vitis vinifera. The list of alien species, most widespread in 50 regions of Europe, includes Robinia pseudoacacia (42 regions), Ailanthus altissima (40), Acer negundo (38), Prunus cerasus (34), Quercus rubra (34), Rosa rugosa (34), Prunus domestica (31). The mitigation of the impacts of these species on local biodiversity is possible via the restoration of local native plant communities, land use organization, strict selection of introduced species prior to the introduction, culture of planting management, preventive measures and extending awareness and sharing of information about plant invasions. Therefore, Ukraine’s spontaneous flora is notable for the active process of naturalization of non-native woody species with considerable involvement of invasive alien species. This is the first and preliminary evaluation of the invasive activity of woody species in Ukraine’s flora. The manifestations of the global tendency of increased involvement and invasive activity of alien woody species in domestic flora have been confirmed. These conclusions are also relevant for elaborating the system of preventive, containing and mitigating measures regarding plant invasions in Ukraine.

Abstract. Large amounts of quarry wastes are produced during quarrying. Though quarry wastes are commonly used in pavement construction and concrete production, in situ utilization during ecological restoration of abandoned quarries has the advantage of simplicity. In this paper, rock fragments 2–3 cm in size were mixed with landfill stabilized waste (LSW) in different proportions (LSW : gravel, RL), which was called LGM. The water content, runoff and plant growth under natural precipitation were monitored for 2 years using a runoff plot experiment. LGM with a low fraction of LSW was compacted to different degrees to achieve an appropriate porosity; water dynamics and plant growth of compacted LGM were studied in a field experiment. The results showed the following: (1) LGM can be used during restoration in abandoned quarries as growing material for plants. (2) RL had a significant effect on the infiltration and water-holding capacity of LGM and thus influenced the retention of precipitation, water condition and plant growth. LGM with RL ranging from 8:1 to 3:7 was suitable for plant growth, and the target species grew best when RL was 5:5. (3) Compaction significantly enhanced water content of LGM with a low RL of 2:8, but leaf water content of plants was lower or unchanged in the more compacted plots. Moderate compaction was beneficial to the survival and growth of Robinia pseudoacacia L. Platycladus orientalis (L.) Franco and Medicago sativa L. were not significantly affected by compaction, and they grew better under a high degree of compaction, which was disadvantageous for the uppermost layer of vegetation.

The nature and rate of breakdown of food reserves in cotyledons varied markedly among species. Embryonic cotyledons of Acer negundo L. stored mostly proteins, whereas those of Ailanthus altissima (Mill.) Swingle were fat-storing. Fraxinus pennsylvanica Marsh, cotyledons contained nearly equal quantities of lipids and proteins (45% of dry weight for each) as did those of Robinia pseudoacacia L. (25% dry weight for each). Total nonstructural carbohydrate contents of embryonic cotyledons of Acer and Robinia (exalbuminous species) were considerably higher than those of Ailanthus or Fraxinus (albuminous species). Carbohydrate contents of Acer and Robinia cotyledons initially decreased, but carbohydrate contents of all four species increased rapidly as cotyledons became chlorophyllous and photosynthetic. Synthesis of cotyledonary chlorophyll and emergence of cotyledons occurred faster for seedlings of Acer and Robinia than for those of Ailanthus and Fraxinus. Protein and lipid contents of cotyledons of all four species declined as cotyledons matured after germination.

Kutatásunk során két fás-szárú özönfajunk: a fehér akác (Robinia pseudoacacia L.) és a mirigyes bálványfa (Ailanthus altissima Mill.) gazdasági potenciálját; visszaszorításának költségeit; és ezek elemeit vizsgáltuk 5 év viszonylatában. Kérdőívet küldtünk ki az érintett állami intézményeknek (nemzeti park igazgatóságok és állami erdőgazdaságok), publikus háttér-információkat gyűjtöttünk, illetve telefonos interjúkat végeztünk az adatok kiegészítéseként. Az adatok kiértékelése során azt tapasztaltuk, hogy a nemzeti park igazgatóságoknak jelentős költségeket jelentett a fehér akác visszaszorítása, melyeket nem tudtak kompenzálni az értékesítésből származó bevételeik. Az állami erdőgazdaságok esetében viszont minden évben a kiadások többszöröse jelentkezett bevételként. A mirigyes bálványfa minden területen negatív megítélés alá esett, értékesíteni nem tudták.

The current state of the Moscow Metro station of the first priority that became operational in 1935 does not allow it to be called a cultural heritage site. This is due to the fact that lighting modernisation carried out by the Moscow Metro was based on fluorescent lamps. Such lamps are more energy efficient compared to incandescent lamps, which were used in original lighting devices specified in the Station Lighting Project developed by architects and designers. However, they significantly changed the station appearance, transforming the originally designed station with entire well visible architectural tectonics?1 from the standpoint of lighting into a simple, flat, unremarkable, and little loaded station of the Moscow Metro./br> This paper describes a method of lighting reconstruction at Krasnoselskaya station by means of original lighting devices that meet modern standards and requirements for cultural heritage sites. The historical analysis on the development of the station lighting environment was conducted during its operation in order to understand what kind of station was conceived by its architects, what changes occurred with its lighting over time, and how it influenced the station appearance and safety of passenger transportation.
