International Ragweed Day - June 24, 2017
What are ragweeds? Why worry? What do we know? What you can do?
Please find all the answers to these questions in this leaflet prepared by the International Ragweed Society (in collaboration with L'Observatoire des ambroisies) for the 2017 International Ragweed Day.
Announcing the International Ragweed Day - June 24, 2017
Based on the proposition of allergologist Prof. Dr. Kristof Nekam and Dr. Tamas Komives the General Assembly of IRS (held in Ascona, Switzerland on October 6, 2011) proclaimed the first Saturday of the summer The International Ragweed Day (IRD) to increase understanding and awareness of the problem this invasive weed causes all over the world. The day was chosen because it is early in the growing season of the plant thereby gives enough time for preparations and actions.
We are inviting our members to take part in the organizing work.

External evaluation of SMARTER: highly successful Action
An external expert has evaluated SMARTER Action, based on the Final Action Report that was submitted concerning the entire duration of the Action.
The Action was valued a lot: "This was a highly successful action that contributed new understanding to the general problem of aggressive invasive species and more particularly proposed management schemes to limit the damage and spread of a particularly aggressive European invader. This combination of basic scientific knowledge and applied management schemes is one of the great strengths of this action."
