We believe we have lost at least one oak tree to oak wilt. We are trying to determine if the oak next to the dead one is also infected. Attached are three pictures. DSC 004 is a picture where the dead oak is in the front left and the oak in question is behind and to the center/right. DSC 009 is standing below the tree and looking up into the branches. DSC 011 is a picture of leaves that have fallen from this oak for identification. We have a couple of other oaks 75 or more feet away but we are trying to determine if when we take down the dead tree should we take the second one as well? Thank you. Jack Jungbauer
