Mr. Bleaney, in terms of the oil sands, one of the habitat remediation techniques is to take a mined area and return it to.... I think it may have been a sphagnum bog, but after the work is done, the best you can do is a savannah forest grassland kind of environment. That seems to me to be not a bad replacement for that habitat. It isn't the same, but it does generate certain kinds of environmental outcomes. What is the experience in the oil sands with that kind of habitat mitigation?
