One incredible find in my review of Saskatchewan legislation was a somewhat tangential visit to Saskachewan Conservation Data Centre to see what invasive plants were being reported … This handwritten checklist by botanist John Howard Hudson, who passed away in 2023 caught my attention. The field experts able to do this are far and few between. All I can say is wow –much gratitude for this kind of dedication and knowledge.
