Event description



A healthy urban forest is invaluable to the health of our city. Trees improve air and water quality, lower air temperatures, reduce energy demand, and beautify the streets.

Stewardship and pruning hugely reduce a tree’s vulnerability to common urban threats such as pedestrian and vehicular traffic, drought and storms. In New York City, where there is limited funding for tree maintenance but significant need, Citizen Pruners provide a tremendous benefit to our urban environment.

Upon successful completion of the final exam, students receive a license from Trees New York and NYCParks to legally prune NYC street trees. Trees New York is the only institution designated to train and license Citizen Pruners in New York City.

“Taking the course has made me aware of a whole realm of the natural world in NYC that I previously did not look at or understand.” - George Shelden, Citizen Pruner

The 12 hour course consists of five sessions- four in the classroom and one field outing.

8 hours in the classroom – Students meet for four 2-hour classroom sessions. The comprehensive curriculum includes tree biology, street tree identification, common tree problems and solutions, tree stewardship and pruning.

4 hours in the field – The Saturday field outing is designed to provide students with the opportunity to practice pruning with their peers under the tutelage of their teacher.
