The Arbor Day ClipArt gallery offers 31 illustrations of trees and tree-planting activities. Arbor Day was first observed in 1872 when Nebraska settlers and homesteaders planted an estimated one million trees on the largely treeless plains. National Arbor Day is celebrated in the US on the last Friday in April. Individual states celebrate on dates that are appropriate to their planting season.
