Förster wrote down my license plate, consequences?

Hello, I drove today with my moped on a dirt road between a meadow and a forest and then drove a bit over a (mowed) meadow and then went into a normal road. There was then a forester standing and wrote down my license plate and meant “that he has what” “because always some cross-country driving”. He has nothing against me in his hand, right? Driving on a dirt road is not forbidden. The farmer has 100% also nothing against it, d I was driving 20m over his property. Can he pin something on me or did he just want to scare me? MfG, Neo
