The Maryland Arborist Association is proud of its history in giving back to the Maryland community. For over 20 years, the members of the MAA have logged thousands of hours and donated hundreds of thousands of dollars' worth of man hours to volunteer for arboriculture service projects across the state.

Each year the MAA chooses a new site to hold our annual Arborist Day event. This event is centered around volunteer work for a local Maryland community that could use the association's help. The Maryland Arborist Association is currently accepting applications from organizations who are interested in being considered for their annual Arborist Day event through June 15, 2023. Learn more here. 

Below you will find the dates and locations of past Arborist Days, along with links to our photo galleries, which can also be found by selecting the links to the left and below.
