Julius Sterling Morton (1832-1902), one of the earliest American conservationists, settled on the treeless plains of Nebraska in 1855. Morton began planting trees and urged his neighbors to do the same. On April 10, 1872, when he proposed that a day be set aside for planting trees, the response was overwhelming: a million trees were planted in Nebraska on that day alone. All 50 states now observe Arbor Day—usually on the last Friday in April. Most observances take place in public schools, where the value of trees is discussed and trees and shrubs are planted. Discuss
