Today, Arbor Day is celebrated in all 50 states and in many other countries. Actual dates of the event differ for each area depending on planting times. Since 1980, every state has designated its own special date for Arbor Day celebrations. Dates are timed to match seasonal conditions appropriate for tree planting in each state. Idaho celebrates Arbor Day the last Friday on April each year, the same date as National Arbor Day.
Trees are the earth's oldest living organisms.
For centuries, trees have provided people with a means to survive in a hostile environment. Trees are a Miracle at Work . Perhaps the best thing about trees is that they're renewable. When a tree is removed harvested we can plant another to take its place. Every year, over 18 million seedlings are planted in Idaho's forests.
