I think tracking falls under stalking and still hunting myself, I use tracks 100% of the time. There don't have to be snow to track animals, the dew is as giving in early morning as is leaves on the forest floor as is high weeds and growed up stuff,low grass is an easy read and dirt/sand is even easier and don't over look little things like "scratches" on rocks/gravel and moss just take your time....if you know what to look for it is very possible to follow "sign" in almost any terrain...also any hunter should use tracks regardless of method used....I have seen hundreds(thousands?) of deer by checking with my binoculars after I have seen a fresh set of tracks, just remember if you see an odd moving branch in the distance take your time and scan carefully being very prepared to change your tactics and when all else fails "jog" a big circle and wait a while......also my opinion of the "BEST" hunter is one who seamlessly blends "ALL" methods listed and uses strategy to boot...
The most important thing when Stalking and /or Still Hunting is to read tracks well, because you may only see 3 deer but there is really 5, and the two that you can't see is the two that will see you the most often. With experience tracks can be read from considerably long distances and can tell you how many critters and which direction/area each is headed/in...always pay careful attention to all your surroundings espeacily other wildlife.
Scout as much as you can and while hunting. Really "scouting" is a speacilized form of tracking in a sense, and is critical to advancing your skills as a hunter, regardless of the animal(s) you intend to kill.
