What is Arborists in the Arboretum Day?

Once a year our arborists friends from the Portland Metro area gather up their tools and swing up to Hoyt for our annual Arborists in the Arboretum Day. Each arborist spends their precious Saturday lending their experience and expertise in the careful care of our collections. We are thrilled to host this boisterous group of colleagues and are amazed at the skill and accuracy with which they do their work.

2011 marked the 26th anniversary of Arborists in the Arboretum Day.  Hoyt Arboretum is happy to welcome over 75 arborists representing 22 different companies. While this event is closed to only our arborist volunteers, feel free to stop by and watch them work - from a safe distance- in the collections.  They will be visiting us on Saturday, September 9th from 8am until 1pm.
