A lot of the Black Walnut trees in the area are dying. I can't quite figure out why. Common trait, most lost a lot of bark just before they died or just after. Some locals blamed a wet spring last year but I'm looking for something more specific. At least 10 trees last year, most over 10 years old, many older, have died within our little village of less than a city block. Central Pennsylvania. Any ideas?
