A slope buried in DSV

DSV or Dog Strangling Vine also known as swallowwort is everywhere in the Don Valley and Riverdale Farm is no exception. We spent most of last week's session removing some of it from one of the slopes. For the time being, we were just pulling it and trying to remove as much of the roots as possible in the process. This method of removal will have to be repeated over several years before we can get rid of it but we're just doing what we can for now. I found an information fact sheet from the city on the subject which is very helpful to better understand the problem of invasive species.
