tree id

Northeast Arizona, a tough place for anything to grow and yet this tree is doing very well.
Any ideas?

It was planted Southwest of the house to provide shade from the afternoon sun. In the winter it's loses it's leaves and the house gets full sun.

When i drive the width of arizona on the 40 i am constantly amazed at the lack of trees around houses or how they are badly positioned .

Maybe?

Other trees on this site similar too.

The uneven leaf blade base points to something in the Ulmaceae. Suspect it may be Ulmus parvifolia, a tree which thrives in the Arizona climate.

Between the rough trunk bark and twig litter it looks like a Siberian Elm to me. I've never heard of one planted on purpose though.

A lot of counties list them as noxious weeds. They are crazy hardy. I've one growing under a power line that I've been cutting to the ground every year for several years and it just keeps coming back. The qualities that make them weeds in some places make the Siberian Elm a great pioneer species in others.

Thank you for your id help.
I just ordered 36 seedlings supposedly two foot tall.

Last year I experimented with planting a couple of trees in november. They were dormant through winter and did very well this year. Through june/july and august i put a sun shade over them. At 6000 feet I'm so much closer to the sun.

Each tree will have to be planted with enough good soil to last a couple years and the hole lower than the surrounding area to collect rainwater.

The trees were cheap. Adding soil and sun shade is gonna hurt.
