24th April is National Arbor Day in the U.S, and is a holiday to celebrate and promote the planting and caring for trees. It began over 200 years ago in 1805 when a local priest in the Spanish village of Villanueva de la Sierra launched the initiative.
Arbor Day began in America in 1872, with an estimated 1 million trees planted in Nebraska. Birdsey Northrop of Connecticut took the message of Arbor Day to Japan when he visited in 1883, and in that same year he became the Chairman of the "Arbor Day Nationwide" campaign, as part of the American Forestry Commission.
With his enthusiasm for the event it soon spread to Canada, Europe and Australia.
