I have many ash trees, up to 60- 80 ft tall, and lowest branches are 40 ft above ground. I have 10-15 this sized losing their bark, maybe drought related here in CT. I have a 700 ft well with 1/2 gal/min refresh rate. Suggestions?
Ash Trees Losing Bark

Ash Trees with bark shedding should most likely be inspected by a qualified Arborist.
The shedding could be due to lack of water or even sun scald; but the Emerald Ash Bore is also a very real issue with Ash Trees.
Your County Extension Office can help you with local tree concerns and also recommend someone to inspect your tree.
Here are some links with more information.
