Yesterday, May 22, was the International Day for Biodiversity. FWG participated but we held an event today, Saturday. The theme this year was invasive species and the focus was on garlic mustard and Rusty Crayfish. At FWG we have no rusty crayfish so the emphasis was on garlic mustard. We had a talk for about 40 minutes on this species, its biology, ecology and advances in biocontrol for garlic mustard. We the then took the group to look at this plant in situ, and after lunch, spent an hour pulling up the stuff. The event was coordinated in partnership with the Canadian Museum of Nature.
