I prefer the US public land approach where different lands are graded for different public uses, and certain areas are off-limits/prohibited to the general public because of practical concerns.
There is a 4300m mountain right by my hometown and while one can hike over much of the mountain and the range that surrounds it, certain areas are off-limits during seasons of the year because the mountain sheep drop and raise their lambs there.

There is no doubt in my mind that, if we actually tried, we could make "batter" forests than "nature". More diversity, more vibrancy, more overall life.
A more local excellent example is the evidence that native north americans would do periodic burns, with many varied benefits for the different ecosystems that underwent such engineering.
