I think mulching with whole logs is a perfectly fine thing to do as well. After all, this is how soil is built in the forest. They are habitat for snails and such, but also beneficial and edible fungi, salamanders, and ring-necked snakes. Very rarely, I have noticed, does one see an abundance of slugs on the forest floor. (However, the forest slugs and snails can be very big and pretty!)
I’m hoping to do more log mulching over the fall and winter.
I also have the resources of pond and river muck, very fertile, in great abundance, as long as I have the strength to shovel and carry it up the hill, which I usually do with a
bowl on my head. They would be a good substitute for compost in building a hugel.
