Arbor Day was first initiated by the state of Nebraska in the United States. Before the 19th century, Nebraska was a bare wilderness with few trees, dry land, strong winds, and yellow sand in the sky, and the people suffered deeply from it. In 1872, the famous American agriculturist Julius Sterling Moulton proposed to establish Arbor Day in Nebraska to mobilize people to plant trees in a planned way.
In the United States, Arbor Day is a state holiday and there is no nationally unified date. But every year in April and May, every state in the United States organizes Arbor Day activities.
