As during previous Symposia we would like to give participants the chance to organize evening workshops on more specific themes not covered in the sessions. We have three slots available, i.e. Monday, Tuesday and Wednesday evenings from about 18h – 19h30. Two workshops could be held in parallel, so this would make for a maximum of six workshops.

The two rooms available for workshops are equipped with beamers and we could accommodate between 20-30 people depending on how we arrange the room. So far we have two workshops planned (for details see below), so there is still room for a couple more. Please send your ideas with a title and short description to Hariet (

Workshops planned so far:

Title: Biological control of grasses
Organized by: John Goolsby, USDA-ARS, Edinburg, Texas, USA
Grasses are invasive weeds in all habitats, climates, and across all continents. Several species have been targeted by biological control. What have we learned from these programs regarding selection of agents, measurement of impacts, and conflicts of interests with those that see many of these target species as valuable to the ecosystem.

Title: Arts and Science of Native Range Explorations
Organized by: Kunjithapatham Dhileepan, Biosecurity Queensland, Brisbane, Australia and Matt Purcell, USDA-ARS, Australian Biological Control Laboratory, CSIRO Health and Biosecurity, Brisbane, Australia
Native range surveys underpin all weed biocontrol efforts, and with emerging new techniques, the exploration science is gaining more momentum. Though only a limited number of research agencies are involved in native range surveys, such a workshop will help new and emerging weed biocontrol research agencies, to understand and appreciate the complexities, regulations and logistic difficulties in the identification and sourcing of weed biocontrol agents.
