“…One of these methods is mowing, which is a common practice at roadsides of the European Alps for both conservation efforts and road safety (ASFINAG 2019). However, mowing can have diverging effects on alien and native plants depending on the individual species and the timing of the mowing event, indicating that this method should be considered on a case-by-case basis (Vitalos and Karrer 2009;Kettenring and Adams 2011;Song et al 2018).…”

Ever-increasing international trade and anthropogenic activity has led to the relocation of thousands of plant species worldwide. So far, the harsh climate of the European Alps historically has restricted the establishment of alien plants. However, new opportunities created by rising temperatures and increasing human activity might allow alien plants to spread further upwards. Here, the distribution of alien plants along an altitudinal gradient in two Austrian valleys is analyzed. Specifically, the distribution along two contrasting corridors (roads, rivers) and the spread of alien plants into adjacent habitats is examined. Following the MIREN sampling protocol, 20 transects composed of three plots along each river and main road, were established in each study region. Plant species cover and a range of site-specific factors were collected. In total, 641 plant species were recorded, of which 20 were alien. Alien species richness along roads was slightly higher compared to rivers, and the composition of the alien flora differed markedly between roads and rivers. Further, alien plant species richness decreases with distance to roads and rivers (indicating that adjacent habitats are less invaded), as well as with increasing elevation. Mowing along roadsides resulted in lower alien plant species cover, but higher alien plant species richness. Finally, compositional dissimilarity between sites showed that elevation, proximity of a plot to a river or road, and alien plant cover are important factors for higher dissimilarity. This study demonstrates that both natural (rivers) and man-made (roads) corridors play an essential role in the upward spread of different alien plants in mountains.

Erigeron annuus (L.) Pers. (annual, daisy or tall fleabane) is an annual herb native to North America but has been introduced and naturalized worldwide. In this study, its complete chloroplast (cp) genome was assembled from Illumina sequencing reads. The cp genome is 153,177 bp long with an A + T-biased base composition. It encodes a panel of 113 genes, including 80 protein-coding, 29 tRNA, and four rRNA genes. Nineteen genes are completely or partially duplicated, while 17 genes possess one or two introns. Phylogenetic analysis suggested E. annuus is mostly closely related to Erigeron canadensis L. and that the two genera Conyza and Erigeron are not mutually monophyletic.

“…Similarly to Bunias orientalis , this species was seemingly introduced to the Sary-Chelek Nature Reserve as a contaminant of imported fodder from Russia, where it is known as one of the most widely distributed invasive plants ( Vinogradova et al 2018 ). This species is highly favoured by mowing, which promotes its local invasion ( Song et al 2018 ); that was apparently the case in Kyrgyzstan, where it was unintentionally dispersed by the inhabitants of Arkyt Village, who used the territory intensely for hay-making (Sennikov & Lazkov, pers. obs.).…”

National checklists of alien plants and detailed databases of non-native plant occurrences are required to study and control regional and global plant invasions. No country in Central Asia has a national checklist of alien plants. A recent inventory counted 183 alien plant species in Kyrgyzstan, including archaeophytes and neophytes, established and casual. This preliminary checklist, which was developed for the Global Register of Introduced and Invasive Species in 2018, served as a starting point for the present study. A complete inventory of Xanthium in Kyrgyzstan has revealed that three alien species are resident in the country. Their correct nomenclature is X. orientale (syn. X. albinum, X. californicum, X. sibiricum auct.; invasive neophyle of the period of extensive grain import to the USSR after the Second World War), X. spinosum (invasive neophyte of the period of the Second World War, which arrived as a contaminant on the relocated livestock) and X. strumarium (syn. X. chinense, X. sibiricum; archaeophyte of the Neolithic period, introduced with wheat cultivation, which had lost its invasive status and appeared on the verge of extinction when its pool was no longer renewed by contaminated grain). A history of introduction to Central Asia is uncovered for all the species of Xanthium. A further spread is documented for Bunias orientalis, with a new record extending its distribution to the Eastern Tian-Shan; a complex history of its introduction to Europe and Central Asia is inferred from the archaeological data and its recent dispersal, and the pathways of its introduction to Kyrgyzstan are established. Erigeron annuus s.str. is reported as new to Kyrgyzstan and Uzbekistan, and E. lilacinus as new to Kyrgyzstan, Uzbekistan, Kazakhstan, Nepal and Tajikistan (it was previously recorded as E. annuus s.l. from the three latter countries, in which the presence of E. annuus s.str. is not confirmed). These closely related species differ in their pathways of introduction and invasion status: E. annuus s.str. is an invasive established alien which was imported as a contaminant of forage, whereas E. lilacinus is mostly a casual (locally persisting) alien introduced with contaminated seed of ornamental plants or nursery material, and also intentionally introduced and locally established in the Botanical Garden in Bishkek. Bidens tinctoria (syn. Coreopsis tinctoria) is newly recorded as a casual alien from a single locality in Kyrgyzstan; this species name is validly published here in conformity with the phylogeny of Coreopsideae. Point maps of species distributions in Kyrgyzstan are provided on the basis of a complete inventory of the literature data, herbarium specimens and documented observations, and our recent fieldwork. The maps are documented with a dataset of herbarium specimens and observations. Period and pathways of introduction, vectors of dispersal, current and historical invasion status, evidence of impact and distributional trend are established or inferred for each species. Each species is discussed in the context of plant invasions in Central Asia as a whole. These species accounts are part of the national database of alien plants which aims at producing a comprehensive overview and analysis of plant invasions in Kyrgyzstan.
