Ahhhhh fellas #1 yes you can call a warden and yes there is some thing he do. The warden probably could not charge him with tresspassing becouse that is under the state police. However he can come on the land and if there was a violation he would indeed charge the guilty party. The land owner has no say if the officer thinks there is some thing illegal going on. If you have the tag # it still not too late to call but you must consider if you will not be able to hunt. Now if ya wana get real real sneaky and not have any one know that you contacted the warden call you local warden tell him whats going on. He will probably meet with you then you can show him how to enter the propety and he can hide and wait being it is not gun season all he has to do is catch the guy with the gun and the sluggs bam he's got him the warden tell's the land owner he has been hearing shots and was investigating and found this guy illegaly poaching deer. The guy is caught the land owner thinks it was a fluke and you get rid of your paocher. Good luck
