As North Carolina’s urban tree canopy declines, the need to continue to plant trees becomes even more important as the state joins in the recognition of Arbor Day.Established in 1872 as a tree-planting holiday, more than a million trees were planted in Nebraska on the first Arbor Day. Today, all 50 states, including North Carolina, and numerous countries around the globe recognize Arbor Day and its celebration of the planting, upkeep and preservation of trees.
