Gateway Park Arboretum Awarded a Level I Accreditation by The ArbNet Arboretum Accreditation Program

Located on the north edge of Marengo, Gateway Park Arboretum has been awarded a Level I Accreditation by The ArbNet Arboretum Accreditation Program and The Morton Arboretum, for achieving particular standards of professional practices deemed important for arboreta and botanic gardens. The ArbNet Arboretum Accreditation Program is the only global initiative to officially recognize arboreta at various levels of development, capacity, and professionalism. Gateway Park Arboretum is also now recognized as an accredited arboretum in the Morton Register of Arboreta, a database of the world’s arboreta and gardens dedicated to woody plants.

Gateway Park Arboretum was created in 2004 with a grant that was used to purchase 70 trees. A collection of conifers was donated and planted that same year. Today there are 36 different species of identified trees and shrubs including 10 species of oaks and 12 species of conifers. A walking trail runs through the arboretum and continues around a 41-acre lake that is part of Gateway Park and Preserve. A meditation garden provides space for trail walkers to pause and rest or reflect. Guided tree walks and educational activities are organized by Iowa County Master Gardeners and Iowa County Conservation Naturalists.

A guided Spring Tree Walk in conjunction with a distribution of free tree seedlings will take place April 23rd at 2 pm. There will also be a tree planting demonstration and door prizes.

Arboretum accreditation is an important step toward achieving the goal of educating the public about the importance and the beauty of trees and their place in the natural world.
