If you own land & want to post it so no one else hunts, fishes, or traps on your land, here are two pertinent links.
One is to the North Carolina Wildlife regulations. It’s a very informative document.
The next link is to the NC Statutes regarding posting your property.
The key is to post the sign no less than every 200 yards along the property line. Plus, post every side of the property and every corner.
If posting with a sign, the sign needs to be at least 120 square inches.
Note: the new rules also permit the property to be marked with PURPLE paint. The stripe of paint needs to be 8” long, painted vertically. The paint stripe needs to be painted between 3’ and 5’ from the ground.
Remember: if you let someone use the land, they’ll need WRITTEN permission signed by one of the owners. In that form, add language that they release the owners from liability for injuries.
You should also strongly consider having some insurance on the property for anyone injured.
