Sheffield Council announced today that the programme will be paused for a couple of days for a safety review to be carried out.
Work is expected to resume next week.
Council contractor Amey is felling trees across the city as part of a £2 billion road improvement programme.
Arborists are felling trees deemed dangerous, dead, diseased, dying or which are said to be damaging streets and pavements.
Objectors to the scheme have staged a number of protests across the city, with demonstrations now held on a daily basis.
Trees earmarked for felling are fenced or cordoned off and a court injunction is in place making it illegal for protesters to enter the safety zones.
But a number of cordons have been breached, leading to a number of stand-offs.
Earlier this month, Amey announced that protesters breaching the cordons would be physically removed by specially trained stewards.
Activity within the zones is being filmed.
