One of our big management techniques out there is doing controlled burns or prescribed burns to try to control some of the non-native grasses, the invasive species that are there. We also do a fair bit of manual weed control—removal of thistle, and things like that. We've begun plant propagation projects out there, collecting seeds from the species that are growing there and trying to actually propagate plants from them to improve the genetic diversity in Winnipeg.
