“Mole starts with M, and and M is for meat” as I once read. Moles don’t eat much plant material, they mostly eat worms and grubs -meat. What does it mean if you have a high mole population? You have a lot of worms, grubs and the like -a thriving ecosystem to sustain the little diggers.
This article gives a little more explanation on how moles benefit their ecology.
Moles also eat young, ground-dwelling cicada nymphs. We were plagued by the adult cicadas this year. If I can get a higher mole population, perhaps I’ll have fewer of these bugs when they’re next due to emerge circa 2029. That would be nice.
