Arbor Day in Guam Date in the current year: October 8, 2024

The first Arbor Day was celebrated in Nebraska on April 10, 1872 and already in 1885 it became an official holiday. Soon it spread to other states of the USA and its unincorporated territories, including Guam. But the date for celebration of this day was chosen to be the second Tuesday in October, that is the end of the raining season. Planting trees during the dry season in April wouldn't do anything good.

Arbor Day is mostly celebrated in Guam by the Department of Agriculture's Forestry and Soil Resources Division and forest activists. This day doesn't attract much attention of all citizens, that's why not so many trees are planted. Annually the Department of Agriculture replaces sick trees on Arbor Day. Volunteer and students may participate in this event to help the staff do their job.
