My Dearest Charleen, I will get a picture of one for you! A pollared tree is where all the lower branches are cut off above grazing height of any Animal. So therefore they cannot eat the leaves or anything else. It is done in spring, so the new growth is cut off, and therefore your cattle-equine species cannot get the new growth which is always more toxic than the old growth, this is because it contains fresh sap!
It has been done here since time can remember and many of our street trees also get it done.
If you know that is not good for your Animals, as in leaves you do this.
I hope you understand it, as until I get a picture it is hard to explain.
Regards.
Neil.
