From an annual membership to spending a few hours volunteering, there are many ways to get involved with the arboretum. We appreciate your support!

Gabis Arboretum is financially self-sufficient and does not receive direct university funding from Purdue University Northwest. We are supported through memberships, admission, rental fees, program registrations, grants and donations.

Our History

The Gabis Arboretum was formerly Taltree Arboretum & Gardens. In 2018, the Taltree Board of Directors and Taltree’s Founders, Damien and Rita Gabis, donated the arboretum and its 300 plus acres to Purdue University Northwest (PNW). PNW has agreed to continue to operate the property, which was renamed Gabis Arboretum at Purdue Northwest, as an arboretum for public, educational, conservation and recreational use.
