Nearly 1,000 people have signed a petition to save a rare tree, which is home to a threatened butterfly species.
The Huntingdon elm in Nether Edge is facing the chop as Sheffield Council says its roots are damaging the pavement and it would cost £50,000 to keep the tree.
But tree campaigners, along with Sheffield and Rotherham Wildlife Trust says the 120-year-old tree on Chelsea Road should be preserved as it is home to the increasingly rare white-letter hairstreak butterfly.
The elm came second in the English Tree of the Year 2016 award.
The petition at www.avaaz.org has more than 960 signatures.
