It's tough to ask about the number of increases of species that have been assessed as being at risk because the number of species assessed goes up over time. What you have to do is look at species that have been assessed more than once and look at whether they've gone up or down or stayed the same, in terms of their status, and where these things only came into effect a couple of years ago, the number of reassessments—I don't know what the number is off the top of my head—I would be willing to bet, is not a very large number that have been reassessed. Even if they have been, they're probably being reassessed based on data that would have been before these changes came into effect anyway.
