Going to take a wild common sense guess here and say no,not allowed.
I have been stopped by a NF LEO and told I could not put out "bait" or a camera in a wilderness area. Was told of a law of no personal belongings left unattended for more than 48 hours in a wilderness. I chuckled and told him I would retrieve them in 47 hours and went about my business. My hours may be off as if has been a few years, but whatever it is, there is supposedly a law about personal belongings unattended to for a certain time period. The camera AND bait were considered personal belongings. I know of cameras, bait, tree stands, etc. that have been up in a wilderness for a long time and no citations were given, though I am not sure if any LEO has found them. Good luck!
If someone wanted to they could probably get you for the caching restrictions ( 48 hour rule) , or the pack it in pack it out expectation. The rules are in place ..have been for a long time... enforcement is another issue. Not likely to get caught unless someone finds your stash and reports it.
There's no legal clarity on the matter. I got into an argument on here awhile back when I got someone on film (on a game camera) stealing a cable I used to secure an elk carcass to a tree stump as camera bait. Through that conversation and afterwards I've done a lot of research, including several conversations with some lawyers that I'm friends with. Long story short - FS and State Patrol or Wildlife Officers are very unlikely to cite you for something without clear instructions from the prosecutor's office. So unless you find yourself on the wrong side of an overly ambitious federal prosecutor (which is very unlikely), you're safe in the grey area. In this case, I'd encourage you to think hard about the ethics of the act and make your own decision. I hunt the east slopes where things are a lot more open and personally don't use bait as part of my own fair chase calculus. On the west side, I might land on the other side of the argument. That's just to say: I personally don't think that the land use designation has that much to do with it. Good luck, and don't let internet forums make the decision for you
