Depends on place. Look at satellite images of Germany or parts of Europe in general and it looks like it's all farms with some fake forest interspersed (the "forest" is itself farmland for wood).
Very few places left that are free from intrusion on land (and none if you count biochemical or atmospheric disturbance). And it's mostly spots that can't be exploited for physical infrastructure, tourism or agriculture.
I've done some back-of-the-envelope calculations with a farmer acquaintance of mine. To preserve a sizable naturally developing habitat you'd need to at least halve Germany's population given current consumption patterns...
