First record of Amaranthus cruentus in Luxembourg

Field of Amaranthus cruentus between Ell and Lannen, 20th September 2017. Photo by Claire Wolff, SICONA.

Amaranthus cruentus L. was first observed in the wild 1 in Luxembourg, on 28th August 2018, on the border of maize fields and a pasture between Ell and Lannen in the Canton of Redange (Midwestern area of Luxembourg).

An on-site inspection on 29th August 2018 revealed that the population extends over 300 m at the edge of the fields and at the roadside between the coordinates LUREF 56775 E | 93241 N and 56758 E | 93542 N. Several specimens were deposited in the herbarium of the National Museum of Natural History.

This population is probably a consequence of the cultivation of this species on an adjacent field in 2017, as the photo on the right illustrates.

Interregional Parliamentary Council issues recommendation on IAS in the Greater Region

On 1 June 2018, the Interregional Parliamentary Council (ICC) has issued a recommendation concerning Invasive plants and animal species in the Greater Region, following the meeting of Committee 4 “Environment and Agriculture” on 27 April 2018 in Remerschen, Luxembourg.

Original document

Excerpt of the recommendations (translated)

The Interregional Parliamentary Council

  1. calls for consistency in the implementation of management measures and objectives (eradication, control, containment) and further exchanges on management methods and priority intervention sites for efficient use of resources;
  2. strongly emphasises the need for coordinated prevention and control actions throughout the Greater Region, on a cross-border basis;
  3. invites all partners in the Greater Region to draw up an exhaustive inventory of public and private bodies responsible for implementing research and methods to combat invasive species;
  4. proposes to support existing mechanisms, such as www.neobiota.lu, for the exchange of information on control methods and the sharing of good practices that have proved effective;
  5. calls for citizens to be informed about the presence of invasive plant and animal species in the Greater Region, the related health and economic risks, and the preventive measures to be taken to protect themselves;
  6. hopes that professionals selling seeds, landscape gardeners and farmers will be made aware of this approach in order to encourage the use of local plant species;
  7. recommends systematic reporting, the development of common tools for identifying and monitoring the most widespread species in the Greater Region, the introduction of monitoring and early detection of the most dangerous species (warning network) and the development of exchanges of good practice at cross-border level;
  8. encourages the control of invasive plants by innovative methods that respect the environment, such as eco-grazing techniques;
  9. hopes that the problem of invasive alien species will be included in school biology courses in order to encourage responsibility from an early age;
  10. stresses the principle of proportionality in order to safeguard animal welfare as far as possible, to take account of the cost-effectiveness of the measures put in place and of environmental protection, in particular by avoiding excessive use of pesticides to combat invasive plants;
  11. calls on the competent authorities to guarantee sustainable sources of funding to run cross-border networks. In this context, European funds are a very interesting financial lever, as shown by the INTERREG V project “InvaProtect, Protection durable des végétaux contre les bioagresseurs invasifs dans les orchgers et les vignes” ; a second project being set up, which aims to provide scientific and technical support to administrations and institutions for the assessment and management of the health risk associated with invasive mosquitoes;
  12. hopes that the implementation of INTERREG projects on invasive alien species will be encouraged in the Greater Region;
  13. welcomes other ongoing projects funded by the EU which make it possible to increase citizens’ awareness and involvement in concrete terms, such as the COST action’Increasing understanding of alien species through citizen science’, in which France and Luxembourg are participating, particularly as citizen participation and empowerment are the best way of controlling the negative effects of these invasive alien species;
  14. calls for closer cooperation between the Greater Region Summit and the Interregional Parliamentary Council to combat invasive plant and animal species as effectively as possible.

The Interregional Parliamentary Council addresses this resolution:

  • to the Government of the French Republic
  • to the Grand East Region
  • to the Saarland Government
  • to the Government of the Land of Rhineland-Palatinate
  • to the Governments of the German-speaking Community of Belgium, Wallonia and the Wallonia-Brussels Federation
  • to the Government of the Grand Duchy of Luxembourg
  • at the Secretariat of the Summit of the Greater Region

DNADIVE – New research project on invasive crayfish

See also the project web page at https://faune-flore.lu/dnadive/

DNADIVE aims at developing a molecular toolbox enabling eDNA detection for Invasive crayfish in streams of Luxembourg. This Public2 Partnership project has been accepted by FNR in November 2017 and will start on 1st January 2018. The project will be hosted by Fondation faune-flore and it’s principal investigator will be the French researcher Dr David Porco. Project partnership: Luxembourg National Museum of Natural History (MNHNL), Luxembourg Institute of Science & Technology (LIST), Water management Agency (AGE), Ministry for Sustainable Development and Infrastructure (MDDI), University of Duisburg-Essen (Germany).

Abstract

DNADIVE aims at developing a toolbox for the molecular monitoring of invasive crayfish in the streams of Luxembourg. Three exotic species (Orconectes limosus, Pacifastacus leniusculus and Astacus leptodactylus) and a native one (Astacus astacus) will be targeted for the project.

This molecular toolbox will encompass several techniques of detection comprising (1) a simple amplification method easily performed in a laboratory with few elements, (2) a digital droplet amplification (ddPCR) which is a more elaborated lab method that can allow for a higher detection sensitivity and a possible quantification of DNA that could be related through the proxy of biomass and abundance to the size of the populations detected and (3) an isotherm amplification method (iPCR) i.e. a simple, cost effective approach which will allow for a field detection usable by non-trained agents.

The results will enable the development of a predictive species distribution model for the target species and to infer their impact on freshwater communities through the comparison with previous sampling campaigns. This set of methods has the high potential to efficiently contribute to early detection and routine monitoring of the invasive crayfish species in Luxembourg, thus allowing for a timely and efficient decision-making and appropriate management.

Importance and distribution in Luxembourg

One single documented observation of the species exists for Luxembourg. The plant was observed in 2011 in Luxembourg-Kirchberg by Jean-Claude Kirpach and determined by Thierry Helminger.

Information leaflet on Vespa velutina

Vespa-velutina-flyer-1st-pageThe Asian predatory wasp (Vespa velutina), also known as the Asian Hornet or yellow-legged hornet, is a species of hornet indigenous to Southeast Asia, particularly the tropical regions, from Northern India, Pakistan, Afghanistan, Bhutan, China, Taiwan, Burma, Thailand, Laos, Vietnam, Malaysia, the Indo-Chinese peninsula and surrounding archipelagos.

As an invader in Europe the hornet has appeared in France, Spain, Portugal. Further invasions are expected in various countries including much of Europe.

As it is currently spreading from South towards the North of France, we expect this wasp species to arrive in Luxembourg quite soon. This is why a leaflet was produced to enable people and especially bee keepers to identify the species and report its presence to the authorities.

Download the leaflet in PDF format (3,2 MB) (in German)

The leaflet has been produced by:

  • Ministère du Développement durable et des infrastructures
    • Département de l’Environnement
    • Administration de la nature et des forêts
  • Landesverband fir Beienzuucht
