Future dynamics of biological invasions are highly uncertain because they depend on multiple social–ecological drivers. We used a scenario‐based approach to explore potential management options for invasive species in Europe. During two workshops involving a multidisciplinary team of experts, we developed a management strategy arranged into 19 goal...

Invasive alien species are one of the major threats to global biodiversity, ecosystem integrity, nature's contributions to people and human health. While scenarios about potential future developments have been available for other global change drivers for quite some time, we largely lack an understanding of how biological invasions might unfold in...

While scenarios about potential future developments have been available for other global change drivers for quite some time, we largely lack an understanding of how biological invasions might unfold in...

Future dynamics of biological invasions are highly uncertain because they depend on multiple environmental, societal and socio-economic drivers. We adopted a qualitative scenario approach to explore the future of invasive alien species (IAS) in Europe and created an overall strategy for their management that considers different plausible future dev...

Das LIFE-Resilias-Projekt gab drei Veteranen der Forschung und Bekämpfung der Spätblühenden Traubenkirsche die Möglichkeit, den Umgang mit dieser Baumart im Berliner Wald aus sehr unterschiedlichen Positionen heraus zu diskutieren. Das Ergebnis: Nicht die alleinige Bekämpfung der Spätblühenden Traubenkirsche (STK) ist zielführend. Vielmehr muss der...

Common ragweed ( Ambrosia artemisiifolia L.) is an annual Asteraceae species native to North America which is highly invasive across Europe and has harmful impacts, especially on human health and agriculture. Besides its wide ecological range, particularly its high reproductive power by seeds is promoting its spread to various habitats and regions....

Non-native tree species (NNT) are used in European forestry for many purposes including their growth performance, valuable timber, and resistance to drought and pest or pathogen damage. Yet, cultivating NNT may pose risks to biodiversity, ecosystem functioning, and the provisioning of ecosystem services, and several NNT have been classified as inva...

Ten years ago, the authors gave an overview of the early history of invasive alien plants in plant health. In the last decade, the field has seen further development, which is reported here. This includes new activities at the global scale, e.g. in the International Plant Protection Convention and the Convention on Biological Diversity, on a region...

Road corridors are important conduits for plant invasions, and an understanding of the underlying mechanisms is necessary for efficient management of invasive alien species in road networks. Previous studies identified road type with different traffic volumes as a key driver of seed dispersal and abundance of alien plants along roads. However, how...

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...

It is often very laborious to repel invasive species that already have widely expanded in their new range, irrespective how desirable this might be due to the negative effects they have. Therefore, early detection and early control of the first new populations is particularly important. However, there is little reporting on such timely activities i...

Deterioration or enrichment of the flora? The working group “Neophytes” in the Botanical Society and Impatiens edgeworthii. The working group “Neophytes” was founded in order to enhance the exchange of information and opinions on the subject of invasive alien plant species. The group organises discussion meetings and field trips.

The United Nations has declared 2020 as the International Year of Plant Health (IYPH) with the aim to raise awareness on the importance of protecting plant health in order to ensure human nutrition and to protect the environment. A major threat to plant health is the continuing introduction and spread of noxious organisms or pests. Under the Intern...

Prioritising the management of invasive alien species (IAS) is of global importance and within Europe integral to the EU IAS regulation. To prioritise management effectively the risks posed by IAS need to be assessed, but so too does the feasibility of their management. While the risk of IAS to the EU has been assessed, the feasibility of managemen...

Viele invasive gebietsfremde Arten im Sinne der Bio­diversitätskonvention sind auch Pflanzenschädlinge im Sinne des Internationalen Pflanzenschutzübereinkommens und umgekehrt. Deshalb ist eine enge Zusammenarbeit zwischen diesen Politikbereichen sinnvoll. In der EU gibt es zwei Verordnungen, die nichteinheimische schäd­liche Organismen regeln, die...

Black cherry: forest pest or forest tree, a context dependent perception North-west European forest ecologists and forest managers perceived, and some still perceive, Black cherry (Prunus serotina Ehrh. var. serotina) as their “enemy”. In this paper we trace the history of this Northeast-American tree species in The Netherlands, Belgium, Germany a...

Eichhornia crassipes is notorious as the world’s worst aquatic weed, and here we present all aspects of its biology, ecology and invasion behaviour within the framework of the new series of Botany Letters on Monographs on invasive plants in Europe. Native to the Amazon in South America, the plant has been spread around the world since the late 1800...

Thirty-seven alien plant species, pre-identified by horizon scanning exercises were prioritised for pest risk analysis (PRA) using a modified version of the EPPO Prioritisation Process designed to be compliant with the EU Regulation 1143/2014. In Stage 1, species were categorised into one of four lists – a Residual List, EU List of Minor Concern, E...

Zum Umgang mit der Spätblühenden Traubenkirsche. Seit Langem ist die aus Nordamerika stammende Spätblühende Traubenkirsche eine der meistdiskutierten fremdländischen Gehölze im Forstbereich. Dabei entwickelte sich eine scharfe Kontroverse mit den Extrempositionen " Ausrotten " und " als Wertholz nutzen ". Was sind heute die Grundlagen für eine Ents...

By referring to the examples of two invase tree species, Prunus serotina and Robinia pseudoacacia, this chapter illustrates that perceptions towards introduced tree species vary and change with time.

When faced with a large species pool of invasive or potentially invasive alien plants, prioritization is an essential prerequisite for focusing limited resources on species which inflict high impacts, have a high rate of spread and can be cost-effectively managed. The prioritization process as detailed within this paper is the first tool to assess...

Ludwigia grandiflora (water primrose), a native to the Americas, is one of the most important invasive alien aquatic plants in Europe. In Germany, a first population was found in an oxbow lake of the River Leda in Lower Saxony, north-western Germany, in 2004. Ludwigia grandiflora formed both dense monospecific patches and mixed stands with native p...

Alternanthera philoxeroides presents a high phytosanitary risk for the EPPO region with a low uncertainty rating. A. philoxeroides is already present in the EPPO region in France and Italy. Further spread within and between EPPO countries is considered likely. The overall likelihood of A. philoxeroides continuing to enter the EPPO region is medium....

Myriophyllum heterophyllum presents an overall high phytosanitary risk for the EPPO region with a low uncertainty rating. The overall likelihood of M. heterophyllum continuing to enter the EPPO region is high. The plant is imported into the EPPO region as a misidentified aquatic species for aquaria and ponds and is already established in Austria, B...

1. Introduction The increase in the gloabal trade and transport of plants and plant material increasingly creates new pathways for the entry of new plant pests and diseases; stressing the necessity of phytosanitary risk assessment (PRA). One problem lies in the fact that many damaging alien pests and diseases are considered as harmless in their nat...

This account presents information on all aspects of the biology of Ambrosia artemisiifolia L. (Common ragweed) that are relevant to understanding its ecology. The main topics are presented within the standard framework of the Biological Flora of the British Isles : distribution, habitat, communities, responses to biotic factors, responses to enviro...

Ambrosia artemisiifolia (Ambrosia: Traubenkraut, Beifuß-Ambrosie, englisch: „ragweed“) ist in Europa und Deutschland ein Neophyt, dessen Ursprung in den USA liegt. In den USA ist die allergische Sensibilisierung auf Ambrosia etwa gleich hoch wie für Gräserpollen, und ohne Gegenmaßnahmen könnte auch in Deutschland die Zahl der Erkrankungen durch Amb...

Ambrosia artemisiifolia (ragweed) is a neophyte in Europe and Germany, which originated from the United States of America. In the USA the rate of sensitization against ragweed equals that of grass pollen, and without containment the rate of allergic sensitizations against ragweed pollen will clearly increase. Currently, the most frequent sensitizat...

The aim of the project is to contribute to the reduction of the prevalence of common ragweed (Ambrosia artemisiifolia L.) in European countries in order to reduce the burden on public health, agriculture and biodiversity. This will consist of developing strategy elements for the reduction of common ragweed and its pollen in countries where the spec...

In Germany, an interdisciplinary working group Ambrosia has been established in 2005. The group consists of experts in the fields of botany and ecology, plant protection, medicine and aerobiology. It has met annually and strives to reduce the occurrence and the impacts of annual ragweed in Germany. The conference in 2013 was organised on behalf of...

Case histories of non-indigenous and cryptogenic plant species [in German]

Biological invasions are recognised as one of the biggest threats for biological diversity world wide. Also in Europe the awareness of this threat is recently increasing. Invasive plants in particular call for the reaction of both the environmental sector (nature conservation acts, CBD) and the agricultural (i.e. plant health, IPPC) sector. Most im...

The invasion of Germany by Ambrosia artemisiifolia is likely to have severe negative effects on agriculture and human health. An interdisciplinary working group has launched an action programme to halt the invasion. Due the abundance of potential habitats, official authorities lack the manpower for control and monitoring all affected areas. The wor...

Summary This is a brief history of NEOBIOTA, which was founded in 1999 as a German group interested in bi- ological invasions and evolved into a major pan-European group. NEOBIOTA represents a forum for exchange of ideas and discussion of topics related to biological invasions as well as an interface between science, application and policies. "Neob...

The introduction* of invasive alien plants into new ranges may have significant consequences for habitats and ecosystems. Although many invasive species have had detrimental effects on native species and ecosystems, not all invasive plants cause serious ecological harm. Many plants are unable to establish permanently, and others become naturalized...

Short methodical remark on the mapping of neophytes Many plants, in particular neophytes may successfully be observed from vehicles, some at considerable speed. While many botanists apply this method, it has not been given systematic treatment in the literature. Some thoughts on the potential use of the fast mapping are offered.
