On March 10th 2015, Coastal ISC, BC Parks and BC Ministry of Transportation coordinated a very successful workshop on knotweed to discuss current treatment strategies, and identify knowledge gaps and research needs.
Over 70 individuals attended the workshop from nonprofit organizations, businesses, and provincial and local governments.
We thank everyone who participated in exchanging information during this workshop!
The goals of the workshop were to:
1) Share information about knotweed treatment methods from different locations.
2) Collaboratively identify effective treatment methods and their limitations.
3) Identify future strategies, knowledge gaps, and research goals to increase treatment effectiveness.
4) Contribute knowledge towards developing a revised best management practices document.
