People of all ages and backgrounds from across the U.S. and Canada came together May 20 to break the Guinness World Record for the most trees planted in one hour by small teams.

Organized by the Sustainable Forestry Initiative Inc., more than 200,000 trees were planted simultaneously in 28 communities. The old record was 52,598 trees.

The record attempt involved more than 1,100 participants, including those from the Sugar Pine Foundation, across four time zones. Each team of 25 to 100 people planted trees simultaneously for one hour.

Official confirmation from Guinness World Records is expected six to eight weeks.
