I think you may be crossing your wires on Nature skill and Survival skill. It is very detect oriented. Follow tracks, notice hazards in a natural setting, perceive signs of weather changes etc. .... That said how it stands, I think the intent was for it to be a perceptive skill.
I stand by my reading, though I do understand where you are coming from. The examples in the basic document are pretty distinct:
Int (Nature) is for recalling lore about terrain plants, animals, weather, and natural cycles.
It is a knowledge skill.
Wis (Survival) is to follow tracks, hunt wild game, guide through frozen wastelands, identify signs of owl bears, predict the weather, avoid quicksand.
All of these, except possibly the last, require some active choice by the player to pursue a particular action. Given that, I choose to read "avoid quicksand" not as a perception-based innate response, but an ability to navigate hazards when you are aware of them. It's debatable, and honestly it doesn't really matter. If the last example requires survival to be a perception skill for you, fair enough; it doesn't for me.
The other "iffy" example under survival (for those who want to find things to niggle over) is "follow tracks". I can see the case for that blurring into Int (Investigation): again, though, I don't agree -- I know for myself that I am perfectly capable of stumbling on, or noticing an animal track, or signs that deer are present. That ability, however, tells me nothing about following its path more than a few steps, however -- to actually track something is a completely different skill. So again, for me these remain distinct.
Being a perceptive skill relates directly to previous editions too. I did not like it then too, I did not like that survival looked for tracks but so did search skill it just took longer...
So I am all for it being an outdoor knowledge skill, but that is what nature is...
I'll admit I'm not sure what you are saying here -- I think its the slipperiness of a work like "knowledge" that might actually be an obstacle here. There are different kinds of knowledge, and to my mind they can stay distinct pretty easily. YMMV.
