I have a pack of tame wolves on the loose. What do I do?

In order to defeat a certain flappy guy, I bred up a lot of wolves. Maybe 100, maybe 200...they covered the altar about 3 deep.

During the fight, the perimeter was breached.

They won, but around 30-40 of them are now free roaming the island. It's a big island.

How problematic is this going to be? Can I just never return to this island and avoid losing frames to them? Or do I need to begin a hunting program to try and round them up?

Luckily they are unstarred so maybe they lose to other things when they're not all in a single pack?
