Not according to the State constitution.
Art I, Sec. 9. SEARCHES AND SEIZURES.
The people shall be secure in their persons, houses, papers and possessions, from all unreasonable seizures or searches, and no warrant to search any place, or to seize any person or thing, shall issue without describing them as near as may be, nor without probable cause, supported by oath or affirmation.
Well, being a native born Texian and having hunted here in Texas all my life I can personally testify that Texas game wardens will come on private property and check you out without a warrant. I’ve been checked a few times and can’t count the times I’ve seen them driving around on private property. Anyway, because I was curious about this I did a little googling. It seems that the requirement for a warrant to search private property varies considerably from state to state. In Texas, although is couldn’t find a statute, game wardens seem to have the authority to enter property without a warrant if they believe there is game on said property. Same thing goes for searching houses, cars, campers, freezers, cookers,etc. So, if these postings are correct, game wardens are like the 10 ton gorilla, where can it go? Anywhere it darn well pleases. But, like I said earlier, I haven’t been able to find a statute to support this. You seem to be good at this searching stuff. If you find something post it as I am curious to learn the facts.
