This might be a minor thing though in your outline. I suggest instead of using "Hazards of Tracking." I suggest you should abjure to something like: "The Risks of Tracking." Or something similar.
Hazards to me at least, it feels a little bit too exotic if you know what I mean. Though, tracking could be dangerous I don't think that it would be a technical hazard. You know what I mean? I'm not suggesting this as it's a bad thing to the outline, no. I'm just trying to assist in making the readers feel that tracking isn't as dangerous as the skill "hunting." If I need to be clearer let me know.
Also, you could add Observation as a related skill as you mentioned in your other posts, since you need fairly good eye sight to see any signs of tracks and such. Stealth could be used as well, when one hunter could be stalking prey. He should be stealthy enough to avoid being sighted by the target? Also, how about prerequisites? That probably needs to have a small write up as well.
That's all I have for now. If you need anything cleared up just ask. And I'll probably pop back in here to post again or something.
I hope you find these suggestions... Somewhat helpful.
