The official Iowa 250 tree, a bur oak, has been planted on the Iowa State Fairgrounds in Des Moines. Iowa Ag Secretary Mike Naig and other officials planted the tree, which is native to all 99 counties in Iowa. The tree is part of a larger initiative to plant 250 trees across the state, with the first one being planted at the fairgrounds. The tree can be found between the Riley stage and the fair administration building, serving as a historical marker for visitors to enjoy. Naig emphasized the importance of agriculture in American history and highlighted the role of Iowa in ensuring food and agricultural security for the nation.
