About Arboretums
An Arboretum is a devoted area set aside for specimen plantings of trees, woody shrubs and vines. Distinct from a forest, nursery or park, it is in a sense an outdoor museum of trees. It is a place where many historical varieties of trees are grown for research, educational, and ornamental purposes and where trees and shrubs are cultivated for exhibition.
There are several reasons for a community to support an arboretum.
One reason is that as more people take an interest in caring for their own home environment, it is valuable to have a location where they can see and compare mature plants and to study the different varieties that they may wish to include around their own homes.
Another important role the arboretum plays is in the area of conservation and preservation. Just as zoos have played a vital role in educating people about animals and their habitats and preserving endangered species, arboretums are places where endangered plants and trees can be protected and propagated to preserve the biological diversity of our planet.
A third vital role an arboretum plays in the community is providing an aesthetically pleasing place for people to visit and enjoy. “Green space” is important for not only the physical health of people but also for the spiritual and emotional health of individuals and communities who want to feel in touch with their environment
A Little History
Encompassing seventy acres of natural beauty on the grounds of ZooMontana the Yellowstone Arboretum is a nationally accredited collection of almost 200 species of native and non-native trees, woody shrubs and vines. Original species of native Cottonwoods and Willows are still on the property with new trees planted every year since 1993. The arboretum was accredited in 2018, so in that respect we are a young arboretum. There are 1000 trees on the grounds and can be found throughout the pathways, botanical gardens, animal habitats and Canyon Creek waterway. One tree of each species is signed for easy identification and study. Expanded information on each tree can be found on the arboretum website.
