The BBC Breathing Places Tree O'Clock campaign, which saw thousands of people planting trees on 5 December, resulted in around 500,000 trees planted, according to reports from the corporation.
Although it was confirmed that 230,000 trees were planted during the one-hour Guinness world record bid, the BBC estimated that at least another 270,000 new trees were put in the ground.
The world record for trees planted by hand by any number of people within a single hour currently stands at 653,143.
However, another world record attempt, which took place at the same time and involved the most trees planted by 100 people, was successful.
This world record was for trees planted by hand, by no more than 100 people, at a single site within a single hour.
Guinness World Records has verified that Tree O'Clock teams at three sites each broke the existing record of 18,124.
- 4,000 oaks were among 26,422 native trees put in the ground at Gransha Park, alongside the River Foyle in Northern Ireland.
- Near St Albans in Hertfordshire, the Woodland Trust, aided by scouts and military cadets, boosted London's green belt with 20,326 new trees at Heartwood Forest.
- Another team of Woodland Trust volunteers in Hainault, east of London, helped to revitalise the historic Forest of Essex by planting 20,312 trees.
