Arbor Day
Every Tree Counts: Celebrate trees at the Arboretum and in your community
Illinois observes Arbor Day on the last Friday in April—in 2012 it was April 27.
We celebrate Arbor Day because trees are essential to our lives, from the very air we breathe to their calming force on our minds and communities. So, each Arbor Day, families and neighbors plant thousands of trees. Every year, those trees grow a little taller, and the people who planted them feel a little prouder.
Trees Are Treasures

This Arbor Day, The Morton Arboretum, supported by the City of Chicago, suburban communities, Morton Salt Co., BMO Harris Bank, and The Davey Tree Experts, hung green value tags on several thousand trees.
Beginning April 23, look for them in downtown Chicago and in seven communities: Glen Ellyn, Glendale Heights, Lombard, Wheaton, Downers Grove, Lisle and Naperville.

How Can You Celebrate Arbor Day?
PLANT A TREE
Planting and protecting trees has never been more important. As climate change transforms our world, healthy, long-lived trees can remove climate-warming carbon dioxide from the air and keep it safely locked away.

CELEBRATE IN YOUR COMMUNITY
Observe Arbor Day by planting trees in your community. Each of the 186 Tree City USA communities in Illinois holds a public Arbor Day celebration—your community may have one as well. Schools, libraries, businesses, garden clubs, and tree and environmental boards and commissions often co-sponsor local celebrations.
