“…The seeds are propagated mainly by birds and small mammals. On the northern Black Sea coast Russian olive is considered to be an invasive species (9,30,31). Species introduced to North America also became an invasive plant and causes a number of problems, especially in the semidesert zone (7,8,16,51).…”

SUMMARyVast agricultural fields as well as kurgans and protective forest belts are characteristic, anthropogenic components of the Ukrainian landscape. The paper discusses the role that kurgans and windbreaks could play in the local restoration process of the steppe in areas excluded from agricultural use (abandoned fields, orchards and pastures). Three examples are presented schematically. The investigated areas are located in three different climate-vegetation zones: desert steppe zone, west Pontic grass steppe zone and Pontic herb(-rich) grass steppe zone. Special attention is paid to how the local restoration process of the steppe proceeds. In addition, the effectiveness of the process and the role of alien tree species are assessed.The present study also attempts to identify future research directions which will be useful in a wide range of applications. On a European scale, the steppe vegetation has been destroyed to a greater degree (80-90%) than any other type of zonal vegetation. Therefore, the analysis and determination of regularities in the local restoration process of the steppe are of particular importance.K e y w o r d s : kurgans, windbreaks, recovery on abandoned fields, local steppe restoration S ł o w a k l u c z o w e: kurhany, pasy przeciwwietrzne, zarastanie porzuconych pól, lokalna restytucja stepów STRESzCzENIE Oprócz ogromnych pól, kurhany i pasy przeciwwietrzne są bardzo charakterystycznym, ale całkowicie antropogenicznym elementem ukraińskiego krajobrazu. W pracy omówiono rolę, jaką 86 kurhany i pasy przeciwwietrzne mogłyby odgrywać w procesie powrotu muraw stepowych na tereny wyłączone z użytkowania rolniczego (porzucone pola, sady i pastwiska). Schematycznie przedstawiono trzy przykłady -omawiane obiekty są zlokalizowane w trzech różnych strefach klimatyczno-roślinnych: w strefie stepu piołunowego, stepu właściwego w wariancie ubogim gatunkowo i stepu właściwego w wariancie bogatym gatunkowo. zwrócono uwagę na etapy procesu restytucji stepów i na rolę, jaką w ich przebiegu mogą odgrywać gatunki obcego pochodzenia.W sytuacji, gdy stepy należą do formacji europejskich przekształconych na największą skalę (80-90%) -analiza i poszukiwanie prawidłowości w procesie restytucji stepu mają szczególne znaczenie. Opracowanie ma także nieco szerszy aspekt. jest próbą wskazania dalszych, kierunków badań o znaczeniu aplikacyjnym.

“…Then the species was cultivated along railways and roads, and in plantations in the Black Sea region. Since that period, it spread widely (Protopopova et al, 2006). In the surveyed territory, it occurs as a subdominant species in artificial forest plantations, from where it spreads through the gorges at the limestone outlets, at the border of the thalwegs, and slopes of ravines (see Fig.…”

Results of investigations on the patterns of distribution and dispersal of alien species of trees and shrubs in the territory of a steppe protected area, Yelanetskyi Step Nature Reserve (Mykolaiv Region, southern Ukraine), are presented. We registered within this protected area 10 alien woody species. For the most widespread ones (Ulmus pumila L., Gleditsia triacanthos L., Elaeagnus angustifolia L., Robinia pseudoacacia L.), we carried out ecological analyses. In order to establish the scope of impact of ecological factors upon these species, their specificity, and interdependence between ecological factors, the phytoindication method was applied (Didukh, 2012). The results of our analysis conducted on 12 main ecological factors (as outlined by Didukh, 2011), such as soil water regime (Hd), variability of damping (Fh), soil aeration (Ae), soil acidity (Rc), nitrogen content (Nt), salt regime (Sl), carbonate content in soil (Ca), thermoregime (Tm), climate humidity (Om), continentality (Kn), cryoregime (Cr), and light intensity (Lc), show that dispersal of model alien species does not have ecological limitation. However, E.angustifolia and R.pseudoacacia have the strongest capacity to penetrate the steppe communities, especially disturbed ones. Further dispersal of these alien species in the studied area and adjacent territories is hampered only by the integrity of the structure of steppe communities.

“…Clearly, we have not found the probable origin of U.S. plants assigned to the black cluster, and more collections need to be analyzed from Asia, especially from the proposed native range, in order to better understand Eurasian population structure and origins of U.S. plants. Alternatively, because most of the historical native range of E. angustifolia has likely been severely altered and the native genotypes extirpated and because this species has been in horticultural trade for centuries (Protopopova et al 2006), perhaps we will never find the true native wild plants but can only track the U.S. invasion back to Eurasian cultivars and naturalized plants.…”

Invasions can be genetically diverse, and that diversity may have implications for invasion management in terms of resistance or tolerance to control methods. We analyzed the population genetics of Russian-olive (Elaeagnus angustifoliaL.), an ecologically important and common invasive tree found in many western U.S. riparian areas. We found three cpDNA haplotypes and, using 11 microsatellite loci, identified three genetic clusters in the 460 plants from 46 populations in the western United States. We found high levels of polymorphism in the microsatellites (5 to 15 alleles per locus; 106 alleles total). Our native-range sampling was limited, and we did not find a genetic match for the most common cpDNA invasive haplotype or a strong confirmation of origin for the most common microsatellite genetic cluster. We did not find geographic population structure (isolation by distance) across the U.S. invasion, but we did identify invasive populations that had the most diversity, and we suggest these as choices for initial biological control–release monitoring. Accessions from each genetic cluster, which coarsely represent the range of genetic diversity found in the invasion, are now included in potential classical biological control agent efficacy testing.
