Bikers are being warned not to stray off the beaten track if they're looking for places to see the TT.
The government says a TT visitor was fined by police after a farmer contacted rangers to tell them a rider was in an Area of Special Scientific Interest in the Island's central hills.
Motorbikes are only allowed on green lanes and greenway roads to avoid disturbing ground-nesting birds and destroying peat habitats.
Environment, Food and Agriculture Minister Clare Barber MHK says riders should be responsible.
