We went for a walk in the park yesterday and saw two chopped down tree trunks. Each had a collection of these stud things. I wonder whether anyone might know what they were put there for.

Can’t view the photos, the links just take me to google 
Got a 404 on both of those 
And the answer is …
404. That’s an error.

Sorry. These photographs are on my computer and phone in Google Photos. The forum said that I could just drag them and drop, which is what I did.
If anyone can explain to me how I can upload them on to here I should be very grateful.
I just click on the ‘image’ icon in the reply/post box - which takes me to my photos on the PC - double click on the one I want - and it inserts it.
Drag and drop doesn’t work for me either.
Thanks ST. I think this seems to have worked.
I’m sure I must have posted pictures before but can’t remember what I did!
Those studs remind me of surveyor’s datum points of some 55+yrs ago. I can remember driving some into tarmac while at uni.
Are they to try and kill the stump off maybe
I agree with Chillie. Studs to kill the tree.
I believe they used to use copper nails?
Ah, thanks both.
Yes, it’s quite logical that they want to prevent further growth and, yes, they do look like copper nails.
Makes note in diary ‘some one agrees with me’ 
Don’t let it go to your head coz it wont last 
Copper nails as Mups suggested. They might also be there to stop people from sitting on the stumps.
Actually, I find the suggestion that they are to prevent further growth convincing. Less so the idea that they are to prevent people from sitting on the trunk bases as they are pretty flush with the surface.
Sometimes they use some kind of toxic chemical to eat into the stump and destroy it underground. Wouldn’t want yer average John or June to sit on it and burn their bums JB…
