Adverse possession laws actually reward bad neighbors. If your neighbor takes over your yard, and say, builds a hedge and maintains it for the state prescribed number of years, he can take it over through an adverse possesion action.

So, yes, survey the property and let him know that the property is yours. The funny thing about adverse possesion is that you can defeat a claim if you tell the person you give them permission to use it.
