Clear cutting timber? Not today...
The first was taken in 2005. The field is directly in the middle, with smaller "chunks" within it. The field is owned by the DNR, and he rents it from them. They have certain conditions he has to follow, such as certain crop rotations, etc.
The second picture was taken in the 1930s (1937-39). This is in exactly the same location as the first shot. Compare the two. Notice something missing in the second one? Trees, maybe? My guess is everyone was going down to Sweet's Marsh to get their weekly supply of firewood during the winter.
I've heard a statistic that there are more trees in the US now than there ever has been. I don't know if that statement is true or not, but I'll bet there are a lot more trees now than 80 years ago. Of course, this is ancedotal evidence, and some treehugger will say there is mass deforestation of the habitat of the spotted liver owl in North Catahoula or something, but I can show you other old/new photos, especially from the Iowa Geographic Map Server, that shows we've had significant reforestation in Iowa over the years.
