The most widespread invaders are, in terms of with temperate Asia among them. To contribute the number of regions from which they are reported, towards closing this gap, we provide a standardized Acer negundo, Echinocystis lobata (recorded in 34 list of invasive alien plant species with their distribu- regions), Erigeron canadensis and Elodea canadensis tions in 45 Russian regions, and relate the variation in (recorded in 30 regions). Most invasive species in their richness to climate, socioeconomic parameters Russia originate from other parts of temperate Asia and human influence. In total, we report 354 invasive and Europe. There were significant differences in the alien species. There are, on average, 27 ± 17 (mean ± representation of life forms between the European, SD) invasive plants per region, and the invasive Siberian and Far East biogeographical regions, with species richness varies from zero in Karelia to 71 in perennials being over-represented in the Far East, and Kaluga. In the European part of Russia, there are 277 shrubs in the European part of Russia. The richness of invasive species can be explained by climatic factors, human population density and the percentage of urban Regional Contributors: See Appendix S1. population in a region.

Vinogradova et al. criteria and covering 83% of the territory of this naturalized plant species inventories worldwide (van country. Kleunen et al. 2015;Pysˇek et al. 2017) show that there are still some major data gaps in global coverage, the Keywords Climate Á Exotic plants Á Invasive flora Á biggest one being large parts of temperate Asia (see Life-form Á Russia Á Socioeconomic factors van Kleunen et al. 2015, their Fig. 1). Global knowl- edge of the distribution of invasive plants, i.e. the subset of naturalized plants that rapidly spread over large distances from focal populations (Richardson Introduction et al. 2000; Blackburn et al. 2011), is even more limited than is the case with naturalized plants and up In recent years there has been considerable progress in to date information on numbers of invasive plant developing regional inventories of alien plant species species in world regions has only been summarized (see Pysˇek et al. 2017 for an overview). Such recently (Pysˇek et al. 2017). inventories represent key inputs for continental and Improving the knowledge of distributions and global databases (Lambdon et al. 2008; van Kleunen richness of alien plant species, both naturalized and et al. 2015) that provide data for testing general invasive, in poorly studied regions is important for hypotheses on biological invasions (e.g. Dellinger many reasons including better understanding of fac- et al. 2016; Maurel et al. 2016; Razanajatovo et al. tors determining local invasions, but also for obtaining 2016; Dawson et al. 2017), identifying long-term a more complete picture of global alien species trends in species introductions (Seebens et al. 2017)as richness (Pysˇek et al. 2008, 2017; van Kleunen et al. well as drivers associated with invasions (Pysˇek et al. 2015). Only thoroughly compiled inventories that aim 2015; Seebens et al. 2015; Dawson et al. 2017). As at obtaining complete lists of alien species for there are clearly documented impacts of alien plants individual regions, provide a robust basis for analyses on the environment and human livelihoods by a subset of regional levels of invasions and underlying drivers of alien species (Vila` et al. 2010, 2015; Pysˇek et al.

Even if such inventories do not 2012; Kumschick et al. 2015; Rumlerova´ et al. 2016), record all alien species, specifically casuals or less biological invasions have become a focus of national widely distributed naturalized species that are difficult (Essl et al. 2011; Pergl et al. 2016b) and international to capture in countries with a poorer tradition of policies (Hulme et al. 2009; Genovesi et al. 2015; floristic research, it is important to aim at complete- Pergl et al. 2016a). ness for the category chosen for the study, be it Comprehensive and rather complete lists of natu- naturalized or invasive species (Latombe et al. 2017). ralized alien plants in regions (countries, islands, With regard to coverage of administrative regions, federal states or provinces of large countries) using a the largest current gap refers to Russia. The European standardized classification of invasion status, mostly region of Russia has largely been accounted for in the following the one proposed by Richardson et al. GloNAF database of the world’s naturalized floras (2000), started to appear in the 2000s. For example, in (see van Kleunen et al. 2015; Pysˇek et al. 2017 for Europe, the first national alien plant species checklists details), as were some regions in the Far East. were published in 2002 for Austria (Essl and Rabitsch However, data from the Asian region of Russia is 2002) and the Czech Republic (Pysˇek et al. 2002).

Indeed, despite numerous local were based on field knowledge, literature, herbarium papers and reports on the presence of alien plant and unpublished records. We considered also aliens of species in different subregions of Russia (Mayorov Russian origin, i.e. species that are native in a part of et al. 2012; Rzhevuskaya 2012; Tremasova et al. 2012; Russia but alien to another part (similar as aliens in Antonova 2013; Panasenko 2013; Silaeva and Ageeva and to Europe in Lambdon et al. 2008). 2016), no summarizing inventory of invasive species Data on life form and geographic origin of the in individual regions of this country has been compiled species were extracted from the working database so far. In this paper we aim at closing this gap for a GloNAF (van Kleunen et al. 2015; Pysˇek et al. 2017) large part of Russia.
