Join Urban Forest Supervisor Andy Dahl for a Campus Tree Tour on Tuesday, May 13, 1:00 p.m., meet on the east side of Macbride Hall (entry to Museum of Natural History). Your UIRA Program Committee host is Nancy Langguth, nancylangguth@uiowa.edu.

On the UI campus there are almost 9,000 trees, comprising over 350 species and countless cultivars in maintained areas. Of note are two Conifer Reference Gardens as recognized by the American Conifer Society, a Literary Grove featuring trees with connections to famous authors at the world-famous Writers’ Workshop, a Querceretum (oak collection), an extensive collection of gingkoes, and several current or former Iowa State Champion trees.

Andrew Dahl has been the campus arborist at the University of Iowa for 25 years. In that time, the University has achieved Tree Campus USA designation in the past 16 years and became an Accredited Level II Arboretum through ArbNet in 2021. Andrew became an International Society of Arboriculture certified arborist in 1995. He has been awarded Urban Forestry Professional of the Year by both the Iowa Urban Forestry Council and the International Society of Arboriculture, the Award of Merit by the Midwest Chapter of the International Society of Arboriculture, and Outstanding Advocate by Trees Forever.

When Andrew isn’t busy working at the University arboretum, he’s serving on several local and regional tree committees, looking for neat trees to visit, seeds to start, and people to talk trees with.
