There are trees all around my home, trees on my land, wildflowers in my back yard, and pure nature all around.
Some of my previous residences have looked like that too. I won't speak to the situation where you are, but I will relate what I discovered about my locality after putting some thought (and research) into it. From another comment on this article:
The developers have just gotten really good at hiding it: things like strips of trees that border the main roads, blocking the view of the suburban sprawl. Roads that curve pointlessly so that you can't see down the length of them. When you drive through this area you get the impression that it's still somewhat natural land... until you take notice of the long, long lines of cars everywhere. Or the 4-story apartment complexes. Or you take a turn off any main road and get lost in suburbs for days. Or you look at satellite photos from 10 years ago, and compare them to recent photos... that lays it plain. You can hide this stuff from earth-bound humans' line-of-sight pretty well, but not from an aerial photo.
You also have to consider that things that take up a small percentage of the land - like roads - have an impact that extends way beyond the concrete itself. Likely, the definition of "wilderness" they use has to do with humans' effects on ecosystems. Not how aesthetically pleasing it is to homebuyers.
