Cllr Robert Frost, Cabinet Spokesperson for Regeneration and Culture, said: "We can confirm that, sadly, a tree has been cut down by a contractor in error as part of ongoing works to improve Hoyland Town Square.
"We are very sorry that this has happened. The transformation was always intended to feature two trees, including a new tree to complement the existing silver birch. We will make sure that a suitable mature tree is planted, as well as the new tree, which was always planned. We are working with a tree specialist to identify the most suitable replacement.
"Unfortunately, crossed wires led to its removal by contractors working on site on Friday. It was not protected by a Tree Preservation Order, but the plan was for it to remain. We can confirm that both trees will be planted on-site by the end of February in line with the existing programme.
"Despite this unfortunate mistake, we hope residents will still appreciate the new-look Town Square which will be complete in a few weeks. It’s part of our ongoing £30m #PrincipalTowns work to improve local high streets and village centres across the borough."
