The emergence of the prairie grass and wildflower industry was triggered by the 1987 passage
of the Surface Transportation and Uniform Relocation Assistance Act, which added a requirement that all Federally aided highway landscaping projects must contain native wildflower seeds or
grasses. At least one quarter of one percent of all funds expended for a landscaping project must be used to plant native
grasses or wildflowers. Many Midwestern states have also included roadside restoration programs to include secondary road
landscaping.
Interest in using prairie grass as a biomass energy source gained considerable attention with the passage
of the Renewable Fuels Standard in 2006, which showcased switchgrass as a potential contributor to a growing ethanol industry.
