One of our cherry trees has lost about half its leaves. http://i3.photobucket.com/albums/y57/Glanecia/Wedding2009011.jpg >>> an image of its leaves. http://i3.photobucket.com/albums/y57/Glanecia/Wedding2009007.jpg >>> an image of the leaves on the ground.

Our maples and birch are dropping leaves too. http://i3.photobucket.com/albums/y57/Glanecia/Wedding2009007.jpg >>> an image of the tree

I walked around the property and noticed that our hazelnut, lilac, rhododendron, blueberries, bay tree, and apple trees all have the similar spots, but they've not started to drop tons of leaves - but they have dropped a few.

One of our maples, however, has different spots. They're white as opposed to the brown spots on all the other leaves on the property.

I assume that what we have is some sort of bacterial spot infection, but does anyone have a really good idea of exactly what kind of infection this might be? Is it treatable?

I've read that bacterial spot and "shothole," caused by the bacteria Xanthomonas pruni and Pseudomonas syringae aren't easy to treat. I'm no expert, but I'm afraid that might be what our trees have. The spots are brown, and they leave holes in the leaves, and many of our leaves are dropping now - and it's barely mid-July.

Though, would bacterial spot affect all of the variety of trees that we have? It's affected our fruit trees, flowering trees and maple trees. They're all very different.

In the past 24 years, I have never seen these trees with an infection like this. They've always been healthy.

Although, the bay tree that my mother gave us, was planted about three years ago & it did develop spots within a year. We've not treated it with chemicals, because after we plucked off the infected leaves & raked up the dead leaves, it seemed to do just fine. Though, I notice it's got spots again. Maybe the infection came from this tree & spread throughout the entire property?

The only other change that has happened to our property, is that we've recently had about 2/3 of our douglas firs logged. The property gets a lot more sunlight now & the leafed trees aren't shadowed by the firs. I didn't notice the spots until after the property was logged. Would that bring on an infection? Not enough shelter? Shock from getting some sunlight? I doubt it, but I figured it's worth considering.
