Chinese Elm? American Elm?

Phoenix, AZ

I recently planted an English Ivy about 20 feet from this tree and read that the EI can cause bacterial leaf scorch in American Elms. Any thoughts on this? Do I have to worry about that in Phoenix, AZ? Also, what kind of tree is this?! How do you tell the difference?

Recommend contacting county or state extension about whether that disease is found in your area. Not sure that is an American Elm - leaves & bark don't look quite right. As I remember AM has wider leaves with more notable teeth and the bark is courser and darker. But your tree does look like a member of the elm family.
