The red oak came from tops at a clear cutting of an oak wilt pocket and so all stages of oak wilt wood came home. I did ask at the time and spores were not listed as a concern only root grafting. Avoiding the spread of tree disease was not a "hot" topic until emerald ash borer arrived. My guess, the horned beetle larva bored the stacked wood and spread the spores.
I read their suggestion for covering for the first year. I find that rather scary unless you’re in the desert. Especially after the wet year we just has where I live. To cover entirely and weigh down the sides with soil you are getting zero air movement. It’s the same exact method used by some people to speed up the process of cleaning animal skulls. Microbes and maggots make their way in and pick the bones clean. Wet wood, wet ground, zero breathability is something I’d avoid. It would be a shame to do all that work and find out you’ve grown huge mushrooms and earth worm colonies. I’d try and stack it on the premises for a year, then move. I’d top cover it too. Most critters leave when wood is dry. You just don’t want them leaving at your house JMO
