It depends on the type of wetland, but some wetlands certainly are fairly easy to restore. If I'm talking about prairie potholes, as I showed you in some of the slides, simply putting in an earthen ditch plug is a means of restoring those wetlands. You don't have to go in and re-seed the vegetation; the seedbank is already there. You simply need to facilitate that water staying in that base and the wetland vegetation returns.
Depending upon what the wetland type is, it is more difficult to restore some of the bogs and fens. We're learning more about doing that, but some wetlands are fairly easy to restore if you can get people who want to restore them.
