Can anyone help ID this tree?

[CubaPete]

Hi everyone, apologies if this is in the wrong section, I'm not too familiar with this forum yet.

 

I'm struggling to ID this tree, can anyone help please?

Thanks in advance.

I almost forgot to mention that there's two growing very near a nice sized Ash tree.
Apparently they are self seeded.

I also also forgot to mention. These pictures are from 4 days ago.

Doesn’t need the question mark, that’s what it is.

Nice one. That looks like the culprit.
A quick read says to remove all the roots!
That sounds like quite a job

Are you taking the trees out?

Yes, one out already. One to go.

If I was you I’d poison the stumps afterwards, otherwise you might end up with a forest of suckers.

Perceived wisdom suggests drilling and using a systemic before felling gets more translocation to the roots. I have never been allowed to try it for fear of the dying tree attracting unwanted attention.
