The Iowa DOT is seeking ways to improve practices associated with revegetation projects to increase establishment of native grasses and forbs. Iowa DOT has developed various seed mixes for re-vegetation projects (Iowa DOT 2005). Each seed mix has the potential to result in a different plant community. Results from this research project will provide information on the seeding rates for species needed for optimal establishment of grasses and wildflowers in future Iowa DOT prairie plantings as well as determine if current seeding practices are adequate. This information can be used to revise or develop seeding rate recommendations for revegetation projects.
