There's been some discussion on controlling invasive exotic pest plants. Now, we on the Environment Committee—a number of the speakers today—have heard from the Parliamentary Commissioner for the Environment on his recent weeds report, and I think we're all very interested in the importance of controlling exotic pest plants. Many of the submitters that we heard from as well who are the farmers, the leaseholders, of these high country farms also are very committed to this control of invasive exotic pest plants. So, at clause 1, there are some rules that the previous speaker referred to, and they are really around where there might be a by-kill, and the by-kill is of indigenous vegetation. So there are some rules in clause 1 there. So controlling invasive exotic pest plants is permitted where "any associated by-kill does not exceed 200 m2/ha; and"—and there are some other factors in there as well.
