Welcome to HALT-AMBROSIA

HALT AMBROSIA is a research project funded by the European Commission, DG Environment (07.0322/2010/58340/SUB/B2).
The overall aim of the project is to contribute to the reduction of the prevalence of the invasive alien plant Ambrosia artemisiifolia 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 the occurrence of ragweed and its pollen in countries where the species is already established, e.g., Hungary, Slovenia, parts of Austria, and South-eastern Central Europe and for the prevention of further import and spread in countries not yet heavily infested, such as Germany, the Netherlands and Northern European countries. To this end the gaps in the existing information needed for understanding historical successes and failures of prevention, control and eradication activities will be analysed.

This includes

• - a fuller understanding of critical elements in the life history of common ragweed,
  - an evaluation of chemical, mechanical and biological control measures.

Based on these results we will develop successful and cost-effective strategies for eradication and control of Ambrosia.

The purpose of this website is to inform a general public and stakeholders about the findings of the research project, invite comments and observations, and offer contacts to researchers in the group. A members’ area accessible via a login serves the internal communication of the project partners and the EU Commission.
