Membership & Giving
All of the plants, benches, structures and labels in the Arboretum have been donated as gifts to the University of Idaho. Your support of the University of Idaho Arboretum and Botanical Garden will help ensure it grows into the future.
Tax deductible gifts to Arboretum Associates support the core programs and operation of the arboretum.

There are currently several planting projects available for individual sponsorship. The cost to sponsor a project ranges from $2,500 to $5,000. The current list of projects can be found in the addendum to the donor policy (PDF link). This cost covers the expenses of the project and provides $1,000 to the Arboretum’s Centennial Endowment to help provide funds for maintenance and development into the future. Sponsors become lifetime members of the Arboretum Associates. They will be recognized with a 5x7” aluminum sign within the project, and a listing in ArborNotes, the newsletter of the Arboretum Associates.
A gift to one of several endowments that sustain the Arboretum provides support in perpetuity since the principal remains invested and only income is spent each year. Current named endowments that support the arboretum are:
Arboretum Associates Centennial Endowment
Norma and Gene Slade Arboretum Endowment
Elisabeth Zinser and Don Mackin Arboretum Endowment
Presidential Oak Grove Endowment
Bob Steele Family Arboretum Endowment
Named endowments generate income to be used according to the donor’s wishes and provide long term funding for projects. Gifts can be added to any of the established endowments or a named endowment can be established for a minimum donation of $25,000.
