Native Oklahoma tree ID help

[GadDummit]

Here's the trees I'm hoping to identify.

The first one is a short tree with peely bark and it puts off these little red balls of "fruit" about the size of a pencil eraser. I'd really like to cut it down and replace it with any other 20' tall tree. The kids play under this and those fruit stems that fall are very pokey.

The second one has serrated leaves and they feel "hairy' when you touch them. Makes me itchy thinking about it.


Trunk:




Leaves (no fruit that I've seen):










The third is some kinda pine, I think.


Trunk:


Light, feathery leaves:










The last one has spiky berries on it.

Also for what it's worth I put this same post up on another "forest" *hint hint* related forum in the Tree ID section (I'm sure you can figure out which one) and the bastage Admin deleted it because he didn't like my pictures. You know how long it takes to put a post full of pictures together? A long dang time! And thankfully I still had the pictures on my phone. Never using that other forum again.

Here's my thoughts. But i've been known to be wrong:

1. No idea, might be an ornamental?
2. Elm
3. Hemlock
4. Mulberry

I concur with JSeery.

1) No idea
2) Definitely Elm
3) Not sure
4) Looks like Mulberry

 

[CincyBurner]

1) An Asian spp. ? I'll guess Pistache ? Perhaps some of you Southern/ Plains burners might have a better idea.
2) American elm
3) baldcypress
4) white mulberry

1. Chinese Pistachio or some similar tree. Not any native tree.
2. American Elm
3. Bald Cypress or Dawn Redwood
4. White Mulberry
