Current Projects on our Grounds

Though The Morton Arboretum has acted as the champion of trees for more than 90 years, we know a greener future relies on constant improvement. Visitors may notice the following projects currently underway at our 1,700-acre tree museum. Each will help us do our best work, and provide you with the best experience, for many more decades. We thank you for your support as we work to complete them. 

Learn More About South Farm

We are building a new, modern facility to support the day-to-day operations of this world-class botanical institution. As the headquarters of much of the staff that tends our trees and gardens, South Farm supports everything visitors know and love most about the Arboretum. The South Farm project, located south of the Administration and Science Center, began in February 2016 and is expected to be completed in October 2017.

Plant Production Facilities

We are expanding facilities for plant production at The Morton Arboretum. This staff-only space will include two new greenhouses, a soil-storage building, and staff offices. The work is underway on the West Side, south of Godshalk Meadow, in an area knows as Arbordale. Work is expected to be completed in summer 2016.


Learn More About River Restoration

Vital restoration is underway along 1.5 miles of the East Branch of the DuPage River as it flows through the Arboretum. Work involves re-grading the artificially steep, badly eroded banks to give them a more natural, gentle slope. Invasive plants that choked the old river banks are being removed, and the banks will be planted with a variety of native plants, including 850 new trees. Major work began in the fall of 2015 and will take about 18 months.

Updating Drain Tiles

To care for its collection and restore more natural areas, the Arboretum is updating a decades-old network of drain tiles—underground pipes, usually made of clay, designed to drain water away from soil. In some places, the drain tiles are being repaired, with new valves and other controls, as well as some new pipes, to allow staff to manage soil moisture conditions for trees from around the world. In select areas, soil is being restored to remedy erosion caused by collapsed drain tiles. Elsewhere, the tiles are being disabled to allow the natural water flow to return, bringing back habitat for native plants and animals. The drain tile work began in 2015 and is expected to continue through 2016.
