Is There a Difference Between Native Range and the Old Growth?

We had a conversation about differentiating native range from this new term. Ive been kicking around old growth grass lands. Native range you can re establish, because you can go back in and plant that. You can plant that on something that has been anthro,. i can't use that wordetpogena. But one of the big things in the conservation movement that i think has been a big fallacy has been the preservationist. Mine said, and we talked a little about that earlier, to day, it's the same as sustain ability! Misused, it's sustainable like, what does that mean to you?
