Abstract The participation of species of alien origin in the flora of individual regions of the world is increasing. A large proportion of these species pose a threat to biodiversity. Issues of the dynamics of changes in the flora and the scale and pace of the processes, with particular emphasis on the biology, ecology, chorology, and genetic variability of the populations of plants of alien origin, including those alien species which are invasive, have been the subject of many years of research in this field in Poland. The present study is an overview of the state of research on invasive plant species in Poland, including the main results of the basic and applied research which have provided the basis for (i) the preparation of a list of invasive plant species for Poland; (ii) assessing the degree of invasiveness of the species analysed, in accordance with the adoption of criteria and the development of methodological solutions. In this work, a new version of the list of invasive plant species has been prepared on the basis of earlier studies, combining theoretical and practical aspects of definition, and it is compared with the list of invasive alien plant species considered to constitute a threat to the EU and Poland as a member country. The categorization (risk assessment) of invasive alien species along with the identification of the most endangered types of natural habitats is often used in practice in the management of invasive plants in Poland. The results of our research have fed into the formulation of legal regulations at the global and regional levels.

Abstract More than 80 potentially invasive plant species have spread throughout the Cibodas Biosphere Reserve, Indonesia. Recently, research has shown that the surrounding community utilizes more than 50% of these species. Although this utilization provides social and economic benefits, it threatens the Cibodas Biosphere Reserve core zone ecologically. Therefore, this study conducted a risk assessment to determine the invasiveness level of utilized plant species. The evaluation was performed using Hawaii and Pacific Weed Risk Assessment (WRA) scheme. The results show that almost all the potentially invasive plant species are high risk, with scores ranging from 10 to 26, except for Fragaria vesca and Mentha arvensis. The highest WRA score was obtained for Lantana camara and followed by Austroeupatorium inulifolium, Cobaea scandens, Mikania cordata, Sonchus asper, Clidemia hirta, Piper aduncum, Sonchus arvensis, Cestrum aurantiacum, Dracaena fragrans, Passiflora ligularis, Podachaenium eminens, Thunbergia coccinea, and Wedelia trilobata. As most of these species were herbaceous plants obtained from cultivated areas, the risk of invasion into the core zone is low. Based on the findings, the recommended management option to control these species is harvesting, accompanied by containment. Through this method, the community can continue to use the species while controlling the population, thereby limiting their spread.

The 228 species of phytopathogenic micromycetes parasitising alien plants included in the publication «Black book of the flora of Belarus: alien harmful plants» (Minsk, 2020) were identified in the course of the conducted research. It was found that out of 322 plant species listed in this edition phytopathogenic micromycetes were found on 182 species (56.5 %). It is noted that among the phytopathogenic micromycetes only 92 species and intraspecific taxon (40.4 %) belong to the alien species of the Republic of Belarus. Obviously, these phytopathogens are highly specialised and currently parasitise only on these invasive plant species. The remaining 136 species and intraspecific taxon (59.6 %) affect both native and alien plant species.

Phenotypic plasticity affords invasive plant species the ability to colonize a wide range of habitats, but physiological plasticity of their stems is seldom recognized. Investigation of the stem plasticity of invasive plant species could lead to a better understanding of their invasiveness. We performed a pot experiment involving defoliation treatments and an isolated culture experiment to determine whether the invasive species Mikania micrantha exhibits greater plasticity in the stems than do three native species that co-occur in southern China and then explored the mechanism underlying the modification of its stem photosynthesis. Our results showed that the stems of M. micrantha exhibited higher plasticity in terms of either net or gross photosynthesis in response to the defoliation treatment. These effects were positively related to an increased stem elongation rate. The enhancement of stem photosynthesis in M. micrantha resulted from the comprehensive action involving increases in the Chl a/b ratio, D1 protein and stomatal aperture, changes in chloroplast morphology and a decrease in anthocyanins. Increased plasticity of stem photosynthesis may improve the survival of M. micrantha under harsh conditions and allow it to rapidly recover from defoliation injuries. Our results highlight that phenotypic plasticity promotes the invasion success of alien plant invaders.

Extent of plant invasions has been expected to be low in protected areas such as national parks due to low anthropogenic activities and high wilderness. However, recent researches across the world have revealed that plant invasions can be severe in the national parks with negative impacts on the protected species and ecosystems. Unfortunately, the status of plant invasions in the national parks of Nepal is mostly unknown. In this study, we sampled at seven locations inside the Parsa National Park (PNP) to document diversity and abundance of invasive alien plant species (IAPS) and their impacts on tree regeneration. Altogether, 130 quadrats of 10 m × 10 m were sampled. We recorded 14 IAPS in the PNP. Three of the IAPS (Chromolana odorata, Lantana camara and Mikania micrantha) were among the 100 of the world’s worst invasive alien species. C. odorata was found to be the most frequent IAPS with the highest cover. The frequency and cover of the IAPS were higher at the sites close to the settlements than at the sites away from the settlements. The species richness of the IAPS was also higher at the sites closer to the settlements than away. The sapling density of the tree species was found to have declined with the increasing cover of the IAPS suggesting that the IAPS had negatively affected tree regeneration. Our data revealed that the PNP has already witnessed massive plant invasions with widespread occurrence of three of the world’s worst invasive species. Therefore, it is high time to integrate management of invasive alien species in the management plan of the park.

Climate Suitability

Plant invasion has been widely recognized as an agent of global change that has the potential to have severe impacts under climate change. The challenges posed by invasive alien plant species (IAPS) on biodiversity and ecosystem stability is growing and not adequately studied, especially in developing countries. Defining climate suitability for multiple invasive plants establishment is important for early and strategic interventions to control and manage plant invasions. We modeled priority IAPS in Sri Lanka to identify the areas of greatest climatic suitability for their establishment and observed how these areas could be altered under projected climate change. We used Maximum Entropy method to model 14 nationally significant IAPS under representative concentration pathways 4.5 and 8.5 for 2050 and 2070. The combined climate suitability map produced by summing up climatic suitability of 14 IAPS was further classified into five classes in ArcMap as very high, high, moderate, low, and very low. South and west parts of Sri Lanka are projected to have potentially higher climatic suitability for a larger number of IAPS. We observed suitable area changes (gains and losses) in all five classes of which two were significant enough to make an overall negative impact i.e., (i) contraction of the very low class and (ii) expansion of the moderate class. Both these changes trigger the potential risk from IAPS in Sri Lanka in the future.

AbstractDuring the field studies on the floodplain forests of the Małopolska Upland carried out in 2009-2013, the author tried to determine which species of alien and invasive plants could be a threat to the stability of these vegetation communities. Efforts were also made to answer the question, which floodplain forests are particularly vulnerable to the penetration of alien species and in which layers of the forest plant community are the best conditions for the development of the individual alien plant species. During the research, a total number of 344 reléves were made, of which 90 recorded the presence of alien species. The most common were: Impatiens parviflora, Acer negundo and Padus serotina. The highest percentage of reléves involving alien species was found in the riverside floodplain forests of Salicetum albo-fragilis and Populetum albae.

When researchers and managers are asked to rank the issues that prevent adequate control of invasive species, lack of public awareness is at the top of the list (Dehnen‐Schmutz et al. 2018). It is therefore imperative to raise the general public's awareness of the potential risks of introducing alien species into the wild. Green Pioneers, a citizen science project funded by the Flemish Government, (Fig. 1) aims to address this issue in Belgium, across age groups. The project aims to Create awareness on invasive species, highlighting how invasions can be avoided and how to mitigate their impact. Improve communication between citizens and scientists on conservation and invasive plant species. Augment the quality and quantity of data on invasive species. Create awareness on invasive species, highlighting how invasions can be avoided and how to mitigate their impact. Improve communication between citizens and scientists on conservation and invasive plant species. Augment the quality and quantity of data on invasive species. The project is developing three kinds of activity, specifically to attract a broad demographic: - 'Young Pioneers', by developing tools for teachers in science, technology, engineering and mathemathics for school children from 12-15 years old. - 'Online Pioneers', through our online citizen science platform DoeDat.be, by helping with the transcription of label information on herbarium specimens, - and 'Visiteers', by inviting companies and working age people to help us in the collection and to inform them about invasive species. Finally, we will be organizing a BioBlitz in spring 2020 at Meise Botanic Garden where we will celebrate plants and all our Green Pioneers, while also spreading the message of invasive plant awareness. During our 48 hour BioBlitz, scientists, volunteers and citizens are workig together to survey the biodiversity of our Botanic Garden. Ultimately, Green Pioneers aim to encourage recording of alien species by amateur botanists and create a generation of responsible gardeners who understand the consequences of releasing invasive alien plants into the wild.

Invasions of aggressive alien plant species that have a high rate of expansion and pose a threat to ecosystems and their biodiversity have become more active in the 21st century due to anthropogenic disturbances of vegetation cover, the lack of systematic control of their numbers, the expansion of transport corridors, etc. Research for the search of new locations of adventitious plant species is carried out in the Republic of Bashkortostan especially intensively during the last 10 years. The result of this work was the publication of the "blacklist" flora of Bashkortostan [1] including 100 invasive and potentially invasive plants and "Synopsis of adventive species of the Republic of Bashkortostan" [13], who presented data on 457 localities of alien plant species, is not peculiar to the nature of Bashkortostan. This article is an addition to the previously published data obtained during the route expedition research in 2019-2020, conducted in the Western regions of the Republic. More than 150 new localities of 22 invasive and potentially invasive plant species were identified. 11 species are included in the “Black book of flora of Central Russia” [9]. The data obtained clarify and expand the understanding of the modern secondary range of invasive plants on the territory of the Republic.

The problem of invasive plant species is becoming more popular all over the world. The peculiarities of alien plant species is also growing in Latvia every year. Invasive species are the serious problem for natural ecosystem and species protection, in traditional landscape visual conservation as well it shows noticeable economical reducing in farming. Existing flora and its structure was as appearing in approximately 10 000-15 000 years after the last examining. It is still developing, quantitative and qualitative plant changes continue to grow in flora. That has an influence on natural narrowing, distribution and species changes. In Latvia, as well in such city as Daugavpils, such questions as alien plant growing were examined only in some fragments. An alien plant growing was analyzed. The following facts are found the biggest plant concentration is noticed in dry and sunny places well near the artificial plant areas.
