I think "tending" becomes a perspective. I see tending as an agrarian mentality. I know others don't see it that way, but I do. Because I do, I see tending as conscious manipulation, a kind of control, even if the intentions are good. On the flip side, I think other people see anything as tending, that it's all implied through the act of foraging, eating and shitting seeds. If you see it that way, then everything is tending.
It's not that IRHGs don't know what they're doing, it's not like they are unaware of how ecology or biology functions, but it comes down to perspectives of time, history, and place. Taking part in a continuum isn't the same as planning for a future as a separate place. To me, that's how the tending leans on the agricultural mindset. Which is a long way of saying, no, I don't see it as all tending the wild.
