How do I keep bears off of my land?

[LordOfTime]

I know it says in the wiki that construction signs won't stop a bear, will a roundpole fence?, such as the one around my property.

No. You need a palisade.

[burgingham]

Boats work as well.

[Grog]

same with runestones, i heard

edit: ok, just use the bulders.

[sabinati]

cellar boulders will also work

[Pansy]

Also claim it. Animals don't spawn on claimed land.

Actually, if the bear isn't already attacking someone, won't signs and fences keep the bear from seeing them? It won't save you once the mauling starts, but it should prevent it if you don't go outside while the bear's there.

Or do bears wander through fences even in non-combat mode?
