Not that these should be introduced to Europe, but the fence lizard kills lyme disease parasites in my neck of the wood: the lizard blood seems to destroy the parasite in the ticks' guts.
I bet better diversity of habitat will mean more insectivores scurrying through the undergrowth, eating the ticks. I understand some people raise Guinea fowl as a predator. I understand chickens will prey on smaller tick-hosting animals with a little training, and probably eat ticks as well...plus they seem to be part of most forest garden plans for many other reasons.
"the qualities of these bacteria, like the heat of the sun, electricity, or the qualities of metals, are part of the storehouse of knowledge of all men. They are manifestations of the laws of nature, free to all men and reserved exclusively to none." SCOTUS, Funk Bros. Seed Co. v. Kale Inoculant Co.
we found last year that all the baby chicks that were hatched on the place and that ran everywhere really did a number on the ticks. Of course once they get big they become destructive. as long as they are children they dart in and out and really can't scratch up much. (Momma hen runs franticly along the fence and those kids don't mind her).
