I think each location has it's own unique set of challenges & opportunities.

I'm in the subtropics so insects (and certain diseases/fungus) have been a big problem of mine too.

I don't have voles here but I have a family of bandicoots that put holes in the ground everywhere. I don't grow many annuals any more, so they aren't too much of an issue. I'm re-establishing my veggie beds though, so that situation may not last. A permie friend suggested that I become comfortable that they're eating my lawn beetles & airrating my soil for me.

A big part of permaculture is turning a problem into a benefit. I have thought of trapping & eating the bandicoots but I'm not that in need of food sources just yet. 😂

My general approach is to grow things that don't require as much attention. Things that have natural resistances to the local insects & fungi. If the plant can't handle the location, I try a different plant. I really don't want to be molly coddling plants that are unsuited to my location.

Good luck 🧡🤙 

 I’ve realized many of these same things in my journey. It’s nice to share experiences.
