Celebrate Arbor Day. Plant a tree! Arbor Day is a national holiday highlighting the importance of trees. The holiday is celebrated every year on the last Friday in April. The most common way to celebrate Arbor Day is to plant trees.
Take action on Earth Day, April 22, and everyday to preserve and protect our natural environment and its animals. Picking up litter, removing invasive plants, cleaning up parks and roads, recycling programs and simply encouraging friends, family and youth to get outside to experience nature.
