check with the landowner to see if anyone else has access to that land
pull the card/ batteries and leave him a note to contact you if the landowner says no one else has permission.
stick another cam up from his,so you get a pic of the fckr just in case he doesnt contact you.
but i would defo check with the landowner first,you just never know.
you might have the stalking rights but does someone have the vermin rights.
i have encountered this were i was vermin controlling on land i had permission but i didnt know
the land owner didnt have the game rights,this becomes an issue when you meet a fellow with a rifle stalking deer.
