Every year twenty or more PlantAmnesty arborists (all ISA certified) volunteer their time to prune majestic old trees in the King County area. This event is coordinated by the Tree Programs Committee and usually takes place in April, on or near Arbor Day.

Trees can be on public or private property.  To nominate a worthy tree(s), or to find out when and where an event is taking place, please contact us and request a nomination form for Arbor Day Tree Prune (not the same as Heritage Tree).
