Happy Arbor Day! Today is the national Arbor Day for the U.S. In addition, numerous states have adopted the last Friday of April as their Arbor Day as well. That means there are a lot of trees to cover.

The Oaks

In 2006, Congress made it official. The United States of America had a national tree. The Oak.

Our nation’s affection for oaks could been seen well before Congress designated a national tree. Keffer Oak, Wye Oak, Emancipation Oak, Angel Oak. Just like a trusted dog, a loving cat or favorite automobile, we name our oaks.

The District of Columbia and a number of states selected an oak species as their state tree, four of which celebrate Arbor Day today.
