Police and fire crews will be working to cut down on motorcycle nuisance in the Brockholes area.
Patrols are being stepped up in and around the nature reserve over the next week.
Local residents have complained of motorcycles tearing through the area and fires being started in the reserve.
Sgt Michael Sampson said: “The inconsiderate actions of a small minority are causing significant nuisance in the area, harming wildlife and ruining the area for the majority.
“We will be running this operation in the hope we can halt these problems and allow the local wildlife and other users to continue enjoying the reserve and the surrounding areas.
“Bikers who ride around Preston in a dangerous and anti-social manner risk having their bike seized – or crushed – under police powers.
“Residents have told us that they are concerned about motorcycle nuisance and this operation is about addressing that. We will take direct action against anyone we find breaking the law.”
Lancashire Fire and Rescue Service will be joining the clampdown, using an all-terrain vehicle to reach any fires and seize motorbikes during patrols.
