About Arbor Day

In 1854 J Sterling Morton moved from Detroit to the area that is now Nebraska. He and other pioneers noticed a lack of trees, which were needed to act as windbreaks to stabilize the soil and to give shade from the Sun. Morton planted many trees around his own home and encouraged others to do the same.

On January 4, 1872, he proposed a holiday to plant trees on April 10 that year. This was known as "Arbor Day" and prizes were awarded to the counties and individuals who planted the most trees on the day. About one million trees were planted in Nebraska on the first Arbor Day. In 1885, Arbor Day became a legal holiday and was moved to April 22, which was Morton's birthday. In 1989 the official state holiday was moved to the last Friday in April. All states in the US now have an official Arbor Day, usually at a time of year that is has the best weather conditions for planting trees.
