I might ask Michael to help me answer that question.
I'd say that with the work we're doing on the ground, what we're dealing with is the potential that perhaps at some point there might be, say, oil found under that particular property and therefore we wouldn't be able to conduct our conservation the way.... I think that's unlikely for a lot of the properties we have, and it is something that we'd probably try to mitigate as well, so that for habitat and species purposes there wouldn't be any real effect from that.
Now what we need to be thinking about is how we actually keep the same amount of land in that conserved status going forward. In a case where there happens to be drilling that takes place on one property, you don't want to just keep losing that, as my colleagues here have pointed out. You want to be able to replace that in some way. That's partly why we're interested in the biodiversity credits and other kinds of notions that could be part of a plan like this.
