Over the past 200 years, Iowa’s once ubiquitous prairies have been almost totally edged out by farmland and urbanization. Only a fraction of one percent of what used to be remains. It is unlikely that Iowa’s prairies will ever be restored to their full former glory, but some counties are regenerating slivers of native prairie along county roadsides.
The practice, called Integrated Roadside Vegetation Management, cannot reestablish the value of Iowa’s lost prairies, but it does help humans and nature coexist little more sustainably. The strips of prairie:
- Create habitat for species like pollinators, birds and small mammals
- Trap pollutants and sediments that would otherwise contaminate water and soil, like motor oil and road salt, while remaining tough enough to withstand harm
- Promote soil health and reduce flooding by incorporating air and organic matter into the soil structure
- Give drivers a glimpse at the state’s historic beauty
Counties aim to manage these areas sustainably with minimal use of pesticides, strategically timed mowing and burning. These efforts are funded through the Living Roadway Trust Fund and supported by the University of Northern Iowa Tallgrass Prairie Center. Over 100,000 acres have been planted since the start of the program in 2009.
