Hello All, I need some help with trying to figure out what is wrong with my ash tree. I have searched books and online and keep getting different answers...one being EAB (Emerald Ash Borer Beetle, which I pray it is not) I live in North Eastern Nevada and last fall (1 year ago actually) we planted 78 - 15 to 20' trees that we purchased from a tree farm in Idaho. We planted several different species with two of them being the Mancana Ash and the Patmore Ash. Things have been going pretty good with them as we havent lost a single one yet, but now I have discovered a problem with one of the ash. In several different locations of the tree the leaves are turning yellow and drying up to a crunchy state. It seems like the are clustered. I have attached a few photo's for you to look at. Please help me if you can...I would hate for this to spread to all of my trees :(

Thank you so much
Sandy
