How to deal with Voles making mouds on the property

Hi everyone, since November a few small mounds started appearing on my property, and I wasn’t really bothered by that. By now, it looks more like a molehills and they’re everywhere.

Does anyone have experience with this? Are there any “eco-friendly” ways to prevent them from damaging the area further? (For context, I live in Czech republic – central bohemian region)
