It's broader in much of Canada, because people didn't even look for it before, and they got it confused with native species—there are some native, close-by species. There's a better knowledge of where it is in B.C.—it's been found in the Nelson area, for example, but it's been eradicated in that area because there were only a few plants, before it became what you have on the island.
There is more work to be done. The local municipalities are getting more involved because of the health risks to their citizens and kids. Some municipalities are just moving into that, because from their perspectives they didn't have a role—or even an interest—in invasive plants before, and they're becoming more active.
It's an example of a perfect.... I love the plant because it's one people can relate to: it hurts kids. It's a good poster plant.
