But here's something I was surprised to see: the goats ate the bark all the way around, but the tree didn't die. The first year it produced new bark, sent sprouts up from the base, and the crown remained full and deep green.

My understanding: the goats didn't touch the water-conducting xylem, so the roots were able to supply the crown with water. However, the goats did eat the outer phloem which conducts photosynthates to the roots. Basically the roots have been starved. I'm leaving the basal sprouts in hopes that the low foliage will help the roots recover.
