I guess it depends on how you define "ecosystem" and what timeframe you're talking about. Certainly over the centuries we've created many more cropland or pastureland or residential landscape ecosystems than wetland ecosystems. And some might argue that even though its human-made, a created (or restored) wetland is not really an artificial landscape if that's your reference point. Perhaps we need to tighter terminology.

I'm not necessarily talking acreage here - foresters might have the edge there (as I leave myself open to criticism from foresters about artificial forests), but actual projects. Mind you, this is a gut feeling on my part with no actual data - which is the point of my query. Does anyone have any citations on this topic specific to wetlands or just on how many artificial landscapes we create in the US each year? Thanks - just another odd question from moi.
