As First Lady, Lady Bird raised hundreds of thousands of dollars to beautify Washington, D.C. She lobbied for passage of the $320 million Highway Beautification bill, which passed in 1965. Known as the ?EUR??,,????'??Lady Bird Bill,” the legislation regulated the number of roadside billboards and replaced many of them with trees and wildflowers. The Texas wildflower program, however, dates back to 1932, when the Texas Highway Department hired Jac Gubbels, its first landscape architect, to maintain, preserve and encourage wildflowers and other native plants along rights of way. This program has expanded into full-scale vegetation management. TxDOT buys and sows about 30,000 pounds of wildflower seed each year.

She was also a spokeswoman for the Conservation of Public Lands Act and clean air and water legislation, which laid the groundwork for the formation of the Environmental Protection Agency in 1970.

In 1969, she founded the Texas Highway Beautification Awards, and in 1992, the LBJ Foundation established the national Lady Bird Johnson Conservation Award.
