Restoration at the Arboretum  

Assisting the recovery of Arboretum woodlands, wetlands, prairies, and streams

Content Detail

At the Arboretum, more than 900 acres are managed as natural areas.

On these lands, staff and trained volunteers work to restore and conserve plant communities that naturally occur in the upper Midwest, including oak-dominated woodlands, grasslands, and wetlands.

The land is home to magnificent oaks and other native species that have been there for centuries. The natural landscapes at the Arboretum have been marked by their history of human settlement.

The Arboretum was created in 1922 from farmland and wood lots. For nearly 100 years, it had been used to raise wheat, corn, and hay; for cattle grazing; for lumber; and to harvest firewood. Prairies and some woodlands had been cleared and plowed, and wetlands had been artificially drained to create farm fields.

Today, the goal for the Arboretum’s natural areas is to recover healthy populations of native plant and animal communities on the land and to foster as much native biodiversity as possible.

Although management strategies are informed by historic land use records—as well as by current research and monitoring—they do not aim to recreate the earlier ecosystems of a specific era, such as the period before non-Native settlers inhabited the Midwest in the 1830s and 1840s. Conditions have changed too much and the future is too uncertain.

Ecological restoration at the Arboretum now aims to assist the recovery of the native ecosystems, while remaining alert and adaptive in the face of new challenges—such as ongoing climate change, surrounding development, and invasive plants, pests, and pathogens.

Restoration means adjusting conditions and processes to allow native species to recover. In some places, it means removing plant species that are considered harmful to native biodiversity, or opening up shady woodlands to allow more sunlight. It may mean allowing water to flow naturally through the site, reintroducing fire into communities that depend on it, or recreating prairies from farm fields.

In the more than 50 years since the Arboretum’s Schulenberg Prairie became one of the first efforts to return farmland to a prairie ecosystem, restoration work at the Arboretum has informed and inspired conservation efforts throughout the Midwest and the world.

Research, knowledge, and multiple strategies are being used to conserve and restore the Arboretum’s natural areas.

It takes knowledge, planning, adaptation, and time to conserve and restore natural areas. Natural areas face challenges, including invasive plants insects, diseases, and groundwater and surface water flow that has been altered by development.

Restoration work is combined with the Arboretum’s research to improve techniques and expand knowledge. Meanwhile, careful monitoring of trees, plants, animals, and other organisms provides important information about the ecosystems’ health.

Explore natural areas volunteer and training opportunities at the Arboretum.

The Natural Resources Program has more than 200 invaluable volunteers who carry out important restoration work at the Arboretum. The program is open to the public, and anyone can get involved. You do not have to be a botanist, and scheduling is flexible. Contact the Volunteer Office to find out how to become a volunteer with the Natural Resources Team.

The team works throughout the Arboretum’s natural areas, including the wetlands, prairies, and woodlands.

Volunteer crews carry out many different restoration activities essential for maintaining healthy habitats at the Arboretum. Volunteers assist with controlling invasive species, monitoring wildlife and plant populations, implementing prescribed fire, collecting native seeds, planting native species, and other activities.

The team is composed of several Restoration Groups. Please check with the Volunteer Office to find out which groups are currently accepting new volunteers or view current volunteer opportunities.

 

Natural Areas Conservation Training Program (N-ACT)

Interested in learning more about the maintenance and restoration of natural areas? Through classroom study and practical field experience at The Morton Arboretum, the Natural Areas Conservation Training Program (N-ACT) provides the knowledge and experience necessary to be a thoughtful caretaker.

The training is not required to volunteer at the Arboretum, but it is available for those who would like to learn and grow their skill set.

To explore the Natural Areas Conservation Certification requirements, browse available restoration and conservation courses, and find other details, see Get Involved: N-ACT.
