The first Arbor Day was held in Nebraska on April 10, 1872, thanks to the hard work and dedication of J. Sterling Morton.  It was estimated that more than 1,000,000 trees were planted on that day!

The idea quickly spread to other states and nations.  Although there were newspaper accounts of Arbor Day tree plantings in Oklahoma Territory as early as 1890, Arbor Day was first observed “officially” in 1901.   The Territorial Legislature proclaimed that it would be the duty and responsibility of the School Children to Celebrate Arbor Day in perpetuity. 

In March 1982, Oklahoma declared a full “Arbor Week” to better recognize the value of tree planting as well as to avoid the harsh planting conditions of late winter.  Oklahoma’s Arbor Week is the last full week in March.  National Arbor Day is the last Friday in April.

"Other holidays repose upon the past. Arbor Day proposes for the future.”  J. Sterling Morton
