A fresh petition was launched earlier in September and more than 500 people have signed it so far – which makes it eligible for debate at a full council meeting on December 8.
Previously, more than 2,000 people had signed an original petition in a bid to save the much-loved tree, which is subject to a Tree Preservation Order, an order made by a local planning authority to protect specific trees.
The outcry from the public follows a decision to cut down the tree after a planning application, submitted by PRI Insurance Services, was granted permission as a precaution after some householders on Barnard Way raised concerns that it could be posing a danger to the structure of their property.
The application said the action was a remedy to movement in the foundations at the insured property and to ensure the long-term stability of the building.
In June this year, contractors from Peterborough City Council were sent out to bring down the tree, and in a desperate effort to save it, one campaigner, Richard Elmer, stood under the tree while contractors started to cut it down, resulting in the felling being paused.
On August 25, a statement announced that the council had explored options and had concluded that the tree must go, proposing planting replacement trees and also making a sculpture from the oak as a memorial.
