just for clarity tell your neighbor he is not welcome on your property and document the conversation, post no trespassing signs (maybe a message about survivors will be prosecuted, etc.), install game cameras (where they can't be easily gotten to by the scumbag), a trip-wire with a surprise (doesn't have to be lethal but can be fun like a tipping 5-gallon bucket full of (insert your favorite flavor)), put date-stamped picture in your photo album and send copy to local gendarme and prosecuting attorney with previous documentation. i'm assuming that there is currently no hope that you will ever have an amicable relationship with the neighbor. if there is that hope might want to try reasoning first. course i would have an equalizer with me. hope it ends well.
