Celebrated on May 16th
Trees are able to communicate and defend themselves against attacking insects. Scientists have found that trees can flood their leaves with chemicals called phenolics when the insects begin their raid. They can also signal danger to other trees so they can start their own defense.
In one day, one large tree can lift up to 100 gallons of water out of the ground and discharge it into the air. Leaves appear green because chlorophyll absorbs red and blue light energy, causing the green energy to bounce off the leaf’s surface.
The tallest tree in the country is a Coast Redwood growing in northern California’s Redwood National Park. It is 369 feet tall and over 2000 years old! According to the last forest inventory, there are almost 247 billion trees over 1 inch in diameter in the U.S.
