Abstract:The objective of this report was to develop native roadside vegetation best management practices for
the Illinois Department of Transportation. A review of current practices was undertaken, along with a
review of those of other state departments of transportation that routinely use native vegetation for
roadsides. Additionally, literature was reviewed for site preparation and desirable qualities, seed and
species selection and quality control, application of seed, and management of vegetation. To better
understand current practices, we performed a study to assess the performance of existing native seed
mixes and practices along Illinois roadsides. Multiple sites were identified where native seed mixes
were applied to roadsides. Vegetation sampling was performed to identify which species were present
and in what quantities, and was compared to the seed mixes that were applied, to determine which
species were successful. Based on the literature review and study results, numerous
recommendations for native roadside vegetation best management practices were made.
