“…Previous studies from boreal ecosystems in other parts of the world show that boreal woodlands can become susceptible to alien plant invasions under strong disturbance, fire events and propagule pressure (Khapugin, Vargot, Chugunov, & Shugaev, 2016;Rose & Hermanutz, 2004).…”

regions; 1970-2015 time period), we analysed the species pool and frequency of alien vascular plants with respect to geographic origin and life-forms, and the levels of invasion across the European Nature Information System (EUNIS) woodland habitats. Results:We found a total of 386 alien plant species (comprising 7% of all recorded vascular plants). Aliens originating from outside of and from within Europe were almost equally represented in the species pool (192 vs. 181 species) but relative frequency was skewed towards the former group (77% vs. 22%) due, to some extent, to the frequent occurrence of Impatiens parviflora (21% frequency among alien plants).Phanerophytes were the most species-rich life-form (148 species) and had the highest representation in terms of relative frequency (39%) among aliens in the dataset. Apart from Europe (181 species), North America was the most important source of alien plants (109 species). At the local scale, temperate and boreal softwood riparian woodland (5%) and mire and mountain coniferous woodland (<1%) had the highest and lowest mean relative alien species richness (percentage of alien species per plot), respectively. Main conclusions:Our results indicate that European woodlands are prone to alien plant invasions especially when exposed to disturbance, fragmentation, alien propagule pressure and high soil nutrient levels. Given the persistence of these factors in the landscape, competitive alien plant species with a broad niche, including alien trees and shrubs, are likely to persist and spread further into European woodlands. K E Y W O R D SEUNIS, exotic, forest, invasive plants, life-form, neophyte, non-native, origin, tree | INTRODUCTIONGlobalization has triggered a massive spread of plant species to areas outside their native distribution ranges (van Kleunen et al., 2015).Some alien species persist only temporarily as casuals in the new area, while others can overcome local abiotic and reproductive barriers to establish self-sustaining populations (Richardson et al., 2000). Some naturalized aliens become invasive, that is they can spread in large numbers and across considerable distances (Richardson et al., 2000) or can have detrimental environmental and socio-economic impacts Woodlands cover a third of Europe's terrestrial area (Forest Europe, 2015; note that we use "woodland" as a synonym of "forest" in our article). In the past, they were logged and transformed to cropland andother open landscape types on a massive scale (Behre, 1988). Today, most European woodlands are composed of stands where the mean tree age is only 60 years (Vilén et al., 2012). Woodlands-and stands with old trees in particular-are generally thought to be resistant to alien plant invasions given the specific abiotic conditions in their herb layer, such as a dense canopy cover and a thick litter layer (Rejmánek, 2015). However, an increasing number of studies has questioned this assumption (e.g., Essl, Mang, & Moser, 2012;Kohli, Jose, Pal Singh, & Batish, 2009;Martin, Canham, & Marks, 2009;Re...

Мордовский заповедник создан в 1936 году и с этого же года на заповедной территории стали организовывать питомники древесных культур. В период с 1936 по 1955 год был организован ряд питомников Pinus sylvestris L., а также питомники растений-интродуцентов, среди которых были, например, Vitis amurensis Rupr., Cornus sanguinea L, Berberis thunbergii DC. и другие виды. Изучив летописи природы, удалось выявить достоверные сообщения об интродукции на территорию заповедника 14 новых видов. Шесть видов из заявленных в Летописи природы сохранилась до наших дней. К сожалению, не все производимые посадки попадали в Летопись природы, таким образом, на местах организации питомников в 1987 году научными сотрудниками Мордовского заповедника было отмечено 22 интродуцированных вида, 19 из которых сохранились и до наших дней. Многие из них натурализовались, расселяясь в пределах питомника и/или за его пределы. Информации о том, когда и кем были высажены данные виды, в Летописях природы нет. Многие из видов находятся на этапе натурализации и дают самосев. ФинансированиеИсследования проведены в рамках госзадания Министерства природных ресурсов и экологии Российской Федерации по теме НИР № 5-22-31-3.

Protected Areas are considered as an important and widely applied tool for biodiversity conservation. They are especially relevant for conservation of threatened species populations. This paper presents study aimed to investigate population status and suitability of habitat conditions of a regionally Critically Endangered plant species, Bupleurum aureum (Apiaceae). Our research has been conducted in National Park "Smolny" (European Russia). The field studies were carried out in 2008, 2013-2018 in two study sites (Plot1, Plot2). In each study sites, square plots (1×1 m) were established to cover the most number of B. aureum individuals. The population status was assessed on the basis of the morphometric traits of individuals (height of generative individuals, number of umbellulas per umbella, number of schizocarpiums per umbellula), number of individuals per population, age structure of populations, composition of accompanying flora. We analysed relationships between environmental conditions (shadiness, soil moisture, salt regime of soil, soil nitrogen, soil pH, soil moisture variability) and morphometric and population traits of B. aureum to reveal the most influencing environmental factors. We found that at the northwestern limit of the range, B. aureum has relatively low abundance and height of individuals in compare to available data from other parts of its range. The population age structure indicated higher habitat suitability in Plot1 due to presence of both vegetative and generative individuals. At the same time, in Plot2, B. aureum population is under serious threat due to a lack of vegetative individuals noted during almost whole study period. We suppose a forthcoming threat of probable loss of this B. aureum population. Environment data obtained in both habitats of B. aureum populations in National Park "Smolny" (Russia) indicated high relationships between soil moisture and the number of inflorescences formed by plants. We suppose a threat of extinction of the B. aureum population due to the building activity of Castor fiber inhabiting the small river Bakhmustika located nearby of study area. If the small river will be dammed, it could lead to decrease in B. aureum population in both studied sites due to the increase in ground water level.
