Between August 19 and 20, representatives from 42 counties and 2 cities traveled from across Iowa to the Tallgrass Prairie Center at the University of Northern Iowa in Cedar Falls to pick up native prairie seed for their roadsides.
This annual seed distribution is made possible through grant funding, including support from the Federal Highway Administrationand the Iowa Department of Transportation Living Roadway Trust Fund. Counties and cities with an approved Integrated Roadside Vegetation Management (IRVM) plan can request native seed through the Iowa Roadside Management program. The seed is provided in two mixes: the Cleanout Mix and the Diversity Mix.
The Cleanout Mix includes 8 grass and 15 forb species, including 2 wet-tolerant species. The Diversity Mix includes 10 grass and sedge species and 28 forb species, including 3 wet-tolerant species. These mixes are designed for a variety of roadside conditions and are used by participating counties to establish native vegetation along Iowa's roadsides.
This year, a total of 17,618 pounds of native seed was distributed, enough to plant approximately 1,460 acres of roadsides across Iowa!
