Even after retirement from the White House, Lady Bird continued to play significant roles in conservation efforts such as the involvement in the Town Lake Beautification Project and the establishment of the National Wildflower Research Center West of Austin, Texas. Her contributions to conservation issue had granted her the honour of serving at conservation boards, such as the National Park Service Advisory Board and the National Geographic Society’s Board of Trustees, which were important roles in the conservation community. Meanwhile, her contributions to the United States had won her countless awards, such as the Presidential Medal of Freedom, which was the highest civilian award in the United States, and the Congressional Gold Medal, among many other awards.

In her late years, she suffered from deterioration in health, which eventually led to her passing on due to natural causes at the age of 94 in 2007.
