The Dallas Arboretum Community Program helps local children and families in need. Runners and walkers are invited to come together in an effort to raise much-needed funds to support North Texas children with unique educational opportunities at the Dallas Arboretum.

The Dallas Arboretum opens its 66-acre "classroom" and takes its science programming to more than 100,000 students a year, 65 percent of which are poverty-level children. By connecting and engaging students directly with nature, in nature, they increase their knowledge and interest in science and are better equipped for grade-level science expectations and state science testing in the fifth grade. Donations help give children access to vital experiences, expert teaching, understanding and achievement.
