"Putting Down Roots for the Future"

Planting trees for the future and supporting an arboretum is a satisfying decision that can be shared by all. You can be on the ground floor of an arboretum's growth and also support ZooMontana with the donation of a tree or shrub in several areas of the arboretum and at the same time share in the growth of the tree for decades to come. By adopting a tree you are also adopting a new member to your family and contributing to a healthy environment for all families.

A donation of $ TBD and selection of your tree will help the arboretum and Zoo grow for the future. It includes planting, watering, maintenance and nurturing plus a plaque celebrating its adoption. Call the Zoo at (406) 652-8100 for further information.



You can be a part of the new Foster Waterfowl Refuge by adopting a tree to be planted in the Zoo's newest area. It will be available for you and other visitors to view as it grows in our Montana climate and eventually provide  a habitat for birds and other wildlife. Choose from the selections below. We will update each trees availability as the year progresses. A contact form can be found on the bottom of the page.
