Welcome to the
Weed Mapping
Working group of the EWRS


Background on weed mapping

Weed surveys have a long tradition in many European countries. Finland, Hungary and the Czech Republik have started with new initiatives this or last year. Unfortunately, many results of previous surveys in many central and eastern European countries are either not accessible or not published in English yet. The software used and the documentation of data varies from country to country. For some areas, no data are available at all. Most existing weed maps show the distribution of weeds only. They don’t refer to a ranking of weeds nor to the severity of weed infestations.

Our working group is open to any person interested in joining us in our mission.

Please contact Garifalia Economou-Antonaka (working group chair) if you want to join us. More details under "Contact us".
