Workshop of the WG 'Weed Vegetation and Biodiversity'

Invitation to the 1st meeting

Prague, Czech Republic, 10th to 12th of May 2023

The first WG event after the merging of the EWRS Working Groups 'Weeds and Biodiversity' and 'Weed Mapping'.


Prague, Czech Republic, 10th to 12th of May 2023

The Working Group 'Weed Vegetation and Biodiversity' is organizing this workshop with the Department of Agroecology and Biometeorology of the Faculty of Agrobiology, Food and Natural Resources of the Czech University of Life Sciences Prague, Czech Republic, and by the Group Functional Diversity of Insects and Plants in Agroecosystems of the Crop Research Institute.

The aim of this meeting is an exchange of current research results and knowledge about documenting population dynamics and regional weed changes, determining the relative importance of abiotic, biotic and management factors influencing the composition, diversity, abundance and damage potential of arable plant communities and identifying and quantifying the benefits of arable biodiversity. The meeting includes an excursion to a nearby farm growing among others the traditional Czech crops hop and poppy.

The major topics are:
  • Rare arable weeds: distribution, conservation, promotion and impact
  • Ecosystem services of weeds
  • Weed seed predation and biotic interactions in agroecosystems
  • Weed surveys and databases
  • Weed diversity and abiotic, biotic and management factors
The scientific program is not limited to these topics, please feel free to submit any research associated with weed vegetation and biodiversity. We look forward to receiving your contributions and hope to meet you all in Prague!
