what is this plant?

I have it all over my back yard

Looks like poison to me.Is the trunk wood looking or plant looking?

Looks like a young tree to me-maybe an elm?

if i had to guess id say its some type of vine like virginia creeper or somethin. grab one and pull it out of the ground.... with gloves if you prefer.

looks like Virginia creeper

Need more photos , side shots, etc. can't tell the leaf arrangement on the stem, whether it is a vine or small seedling, etc.

It doesn't look like the Virginia Creeper around here, but maybe it changed some as it crept all the way up there from Virginia.

upper left, lower left and upper right = Virginia Creeper, upper middle looks kinda like a wild grape leaf. Front and center bottom, I don't know, but I do know if it is the same thing we have around here that looks like that, it is real fragrant,almost pungent when its broken.

Any buckeye trees around? Kinda looks like a sprout to me.

i don't really know what a buckeye tree is

Looks like young Thimble Berry.

berry

Looks like a young Ash tree that we having growing around here.
