The rehabilitation restoration typically involves restoring the hydrology to the system. If the wetland was drained by a ditch or by some diversion of the water, restoring the hydrology to it.... If you create the capacity for the basin to hold water again, the systems come back. They come back to life, and they come back to life very quickly. That's typically the approach that we take.
What are the economics around that? It's expensive to do the restoration. It costs in the order of $10,000 to $20,000 per hectare to put the wetlands back on the landscape.
