Japanese Rose-Tiger Garden
It's starting to be another busy year at the arboretum. The three photos above represent more than 150 new introductions that you'll be able to experience in the arboretum and botanical gardens starting this season This includes both native and non-native plants from North America, Europe and Asia. The majority of these plants are courtesy of collaboration with Bailey Nurseries and the Montana Nursery and Landscape Association. Read more below. The arboretum is also in the process of expanding its association with the Global Conservation Consortium Conifers by securing specimens to add to our existing collection. Volunteers will be busy watering and re-mulching trees this summer season. Would you like to become an arboretum volunteer? Check out below in the right sidebar !

Bamboo Garden
A new addition to the Bamboo Garden has been completed. This add-on compliments the existing garden with new space for added bamboo plants and extra nourishment for the Zoo's growing Red Panda family. Thanks to the Association of Zoological Horticulture for their grant to make this project a reality.

Introducing the New Bailey Collection
The recent announcement of our collaboration with Bailey Nurseries is growing. The new arrivals have been planted and can be seen throughout the arboretum and botanical gardens. Watch for a new addition to the website outlining the locations of all the new trees and shrubs through a mapping program. This will allow our visitors to pinpoint the location of their favorite plants and observe those plants in a more natural environment that's suitable for their own garden location

" MNLA Community Beautification Award "
The arboretum is pleased to announce it's Community Beautification Award from the Montana Nursery and Landscape Association. In their ongoing effort to support members and the communities they reside in, the Montana Nursery & Landscape Association has established a Community Beautification Fund. This program is funded by donations to the live and silent auction fundraiser that is held during the annual MT Green Expo Convention and Trade Show, and grants project funds to communities across the state that meet the certain guidelines.
This year's project features a series of new conifers located along the Zoo's pathway system. The pots feature all North American conifer trees including Montana natives. The trees all have educational signage that gives a brief history of the species. The trees will be nurtured and then transplanted into the MNLA North American Conifer Garden located between the Bison Habitat and the Native American Medicinal Garden.
"Yellowstone Arboretum Participation"
Volunteer Curator Scott Meyers has been selected to participate in "Arboversity", a national training curriculum program through the Morton Arboretum. Scott worked with colleagues from the Morton Arboretum and the new Alexander Caulder Garden in Philadelphia to establish a watering program for trees and plants in arboretums and botanical gardens that can be adapted across the country.
Horticulture staff at public gardens are key stewards of one our most valuable assets: our living collections. Finding, hiring, and retaining these skilled horticulture staff, however, is becoming more difficult.
Formal horticulture training programs are drying up; competition in the labor market is high; and gardens themselves don’t always have the time, resources, or infrastructure in place to support regular training or professional development. Entry-level horticulturists may not come in with the foundation of knowledge needed to effectively care for living collections, and experienced garden staff may not have the time to devote to developing consistent, comprehensive training programs.
To address these issues, The Morton Arboretum is developing a foundational curriculum for horticulture staff that will be applicable across the public garden industry. Training materials will be available for participating public gardens through Arborversity, The Morton Arboretum’s online learning management system.
At the end of this project, we will have developed:
A curriculum, co-created with professionals from across the country, that captures a shared understanding of the basic skills necessary for horticulture roles at public gardens; and
A suite of online courses, in-person training guides and checklists, and other learning materials to support that curriculum

The Yellowstone Arboretum is happy to publish the results of a fascinating study conducted by our MSU-B intern Carey Berendsen. Carey spent two years as part of the internship program learning all the facets of day-to-day operations of an arboretum and the maintenance and mysteries of trees. These studies show the relationship between tree origins and their survival in Montana using Carey's surfaced data based on climate observations and soil health.

"What is Browse"
Arboretums serve as vital, natural, habitats for local wildlife and, in some cases, provide browse (fresh foliage) for zoo animals. Common wild browsers like deer, rabbits, and rodents frequently forage, while, in urban areas, horticulturalists sometimes partner with zoos to provide sustainable browse—such as bamboo, willow, poplar, cottonwood and maple—to herbivorous animals.
Key Aspects of Animal Browsing in Arboretums:
Wild Animal Foraging:
Native herbivores like deer can heavily browse young trees, particularly in winter when food is scarce, potentially causing significant damage to collections.
Zoo Browse Program:
Arboretums like the Yellowstone Arboretum are fortunate to be a part of ZooMontana so collected trimmed branches (browse) can be chosen for Red Panda, Takin, goats, and other zoo animals to provide necessary nutritional benefits and behavioral enrichment.
Ecological Role:
The plants and trees offer food and habitat for various animals, including birds, insects, and small mammals.
Visitors can look for evidence of browsing, such as deer browsing on twigs, rabbit gnawing, or, in some cases, bird damage (e.g., woodpeckers).

Browse is defined as any natural plant material that an animal is
provided access to. This may be given for many reasons including bedding, shelter, enrichment, or as a part of their diet.
The goal of the ZooMontana browse program is to provide an
assortment of safe plant materials to our animals, while at the same time striving to prevent exposing our animals to potentially hazardous plants. This
is done by providing easy to access reference materials such as the respected "ZooMontana Browse Book".
