[ZG] EuropeMots-clés : espèce végétale invasive Résumé : "Ageratina adenophora (Spreng.) R.M. King & H. Rob. (Crofton wéed) is a triploid, apomictic perennial herb or sub-shrub native to Mexico that is highly invasive in many parts of. the world. This species thrives in diverse habitats, from wet forest margins to dry slopes and disturbed urban areas. Initially introduced globally as an ornamental plant, it has now naturalized across many continents, including Europe, Asia, Africa, Oceania, and the Americas, often displacing native flora and altering ecosystems. Its introduction to Europe dates back to the 19th century, with naturalization first recorded on the French Riviera. Ageratina adenophora is now established in several southern European countries (Portugal, Spain, France, Italy, Croatia, Greece) and across the Macaronesian islands. It spreads via wind- and water-dispersed seeds and can also propagate vegetatively, particularly along riparian systems and disturbed sites. Despite its prolific reproduction and adaptability, its expansion in Europe has so far remained moderate, possibly due to climatic limitations and unsuitable habitats. Ecologically, A. adenophora exhibits remarkable phenotypic plasticity and physiological adaptations that enable it to survive a range of abiotic stresses including cold, drought, and variable light levels. The species benefits from mutualisms with soil microbes and displays enhanced nitrogen-use efficiency in introduced ranges. Although initially valued for ornamental and medicinal purposes, A. adenophora is now widely recognized as a harmful invader. It invades both natural and semi-natural habitats and has demonstrated a capacity to alter soil chemistry, suppress native vegetation through competition and allelopathy, and host diverse pathogens and endophytes. Ageratina adenophora negatively impacts biodiversity, ecosystem functioning, and agriculture by forming dense, monospecific stands and disrupting native communities. Its presence in biodiversity hotspots and protected areas—such as Himalaya, South Africa, and the Canary Islands—poses significant conservation challenges. Control efforts, including the use of biological agents such as Procecidochares utifis Stone 1947, have yielded mixed results. The most effective method for small areas is to physically remove A. adenophora before it sets seed. This can be done by hand-pulling or cutting. Given the continued spread and resilience of this species there is an urgent need for coordinated management strategies and increased awareness, especially in the face of climate change which may further facilitate its expansion in Europe and beyond."

(yellow nutsedge) and deals with its taxonomy, morphology, genetic diversity, distribution, habitat requirements, ecology and life cycle, with special emphasis on uses and cultivation, history of introduction, impact and management in Europe. C. esculentus is a tuber geophyte and most likely originates from the Mediterranean and Southwest Asia. It is a variable plant and four wild-type varieties are presently recognized, in addition to a cultivated form. C. esculentus reproduces primarily by its underground tubers, although abundant seeds are produced. In temperate climates, tubers usually sprout in late spring and the plant withers at the beginning of the winter. C. esculentus is only cultivated in the València region in Spain. Invasion foci emerged across Europe at the beginning of the 1980s and at present, C. esculentus is most abundant on arable land and in ruderal habitats, followed by riverine vegetation. In heavily infested regions of Europe, C. esculentus causes substantial yield losses in field crops and although different management strategies are available, C. esculentus remains difficult to control."

Titre : Monograph of invasive plants in Europe N°6: Asclepias syriaca L Type de document : texte imprimé Auteurs : Swen Follak, Auteur ; László Bakacsy, Auteur ; Franz Essl, Auteur ; Lisa Hochfellner, Auteur ; Katharina Lapin, Auteur ; Michael Schwarz, Auteur ; Barbara Tokarska-Guzik, Auteur ; Dan Wolkowycki, Auteur Année de publication : 2021 Article en page(s) : pp. 422-451 Langues : Anglais (eng) Catégories : [Espèces (in biblio)] Asclepias syriaca L. Mots-clés : plante invasive Résumé : "This work synthesizes all aspects of Asclepias syriaca L. (Apocynaceae) including the taxonomy, distribution, history of introduction and spread, ecology, biology, uses and benefits, impacts on biodiversity and agriculture, legislation, and management. Asclepias syriaca is a perennial broad-leaved species native to North America. Introduced for ornamental and various other purposes, such as a source of fibre and rubber, it has become established in many regions of Europe and it had increasingly spread in the last decades (>1980s). Its reproductive behavior is characterized by a high production of wind-dispersed seeds and by the propagation of creeping lateral rhizomes, which allows the species to proliferate rapidly. The species persists in a wide range of edaphic and climatic environments. It occurs particularly in anthropogenic and (semi-)natural habitats, such as roadsides, agricultural land, abandoned sites and grasslands, open shrubland, and forests, respectively. Studies have demonstrated negative impacts on the biodiversity and ecosystem processes in invaded regions, namely in open sand grasslands in Hungary. Asclepias syriaca occurs as a competitive weed in crop fields. Since 2017, the species is regulated by the European Union (EU) under the Regulation No. 1143/2014, which states that A. syriaca is subjected to restrictions such as a ban on importing, selling, breeding and that EU member states are required to place effective management measures. Awareness raising activities are important to inform the public, farmers and stakeholders about the risks of this invasive alien plant. Effective direct control options include mechanical control as well as herbicide application."

[ZG] EuropeMots-clés : plante invasive Résumé : "Ambrosia trifida L. (giant ragweed, Asteraceae) is native to the North American continent and was introduced into Europe and Asia at the end of the 19th century. In its native range, this tall annual species is common in riparian and ruderal habitats and is also a major weed in annual cropping systems. For nearly a century, A. trifida has also been of great concern in the U.5. for its highly allergenic pollen, necessitating targeted control measures to reduce its impact on human populations.
Based on the distribution of A. trifida in North America and in its introduced range, riparian systems in the rest of the world may be particularly at risk to invasion, with potential negative consequences for their biodiversity. Currently, A. trifida has invaded Asia more widely than Europe, Iikely due to the more favourable local conditions in Asia. Throughout its introduced range, A. trifida is host to a Iimited number of invertebrates and pathogens and only a few biological agents are available for its control. The main impacts of A. trifida at a globallevel are on crop yield and human health, resulting in significant socio-economic impacts. The success of A. trifida invasion in areas in which it has been introduced is still undear, but dimate change may increase dimate suitability, increasing the potential for A. trifida to spread. While effective management in cultivated fields seems potentially possible, the development and control of A. trifida in natural riparian habitats is of great concern due to the difficulty of management in these areas."
