Fence

Fences are used to keep curious people off your land (and items), or to keep your animals from escaping. A single part of fence requires 6 wooden stakes. Fences can be used as a trap-fence, which blocks the way of most large animals and guides them straight into a trap, usually a trap pit. The player must climb over them, and NPCs and some animals are also capable of climbing fences.

In addition to keeping domestic animals in place, an open pen with a trap and some herbivore oriented bait such as milkweed leaves can be used to lure a large wild animal in. Once the animal is caught, the pen can be closed off and the animal can be freed or escape from the trap without worry of it running off. Wild "livestock" can be kept in this way as long as the area is regularly visited to prevent the animal from despawning.

In the "Traps" menu (ALT-R) there is the "Build trap-fence" option, that makes the exact same fence as the "Fence" in the "Building options" menu. Fences can be deconstructed to recover the building materials, and they can also be kicked apart with any attack if you are in a hurry (wooden stakes will be destroyed).
