Iowa's IRVM program office is funded by the Living Roadway Trust Fund and located at the University of Northern Iowa. Since 1998 the IRVM program office has applied for and received federal Transportation Enhancement (TE) funds to purchase native seed for planting projects along Iowa's county roads.

82 of Iowa's 99 counties have received TE seed. The map shows the number of years each county has received seed since 1998.

TE activities are community-based projects that expand travel choices and enhance the transportation experience by improving the country's transportation infrastructure. The funds come from the Highway Trust Fund, a repository for the receipts from the federal excise tax on gasoline.
