Ah heck yeah I know where your place is. That is a dandy looking place! I live in Allardt and hunt some around Burrville and Sunbright so Im through there alot. Actually own 50 acres on the other side of Sunbright as of like 2 weeks ago. Those are the old native crabs there, I hope they start doing better. That native crab was wiped out of West Fentress under the Plateau many years ago but has hung on in the higher elevation of the Plateau. I would do everything under my power to save those trees, you might want to think about spraying them if you notice any spots on the leaves. And definitely, definitely, If you see some dead limbs with dead brown leaves on them this summer, cut those limbs off immediately and burn them. That is fireblight and the only way to keep it from spreading is to cut off the infected areas and burn.
