Trees are more than just part of our natural landscape. They provide shelter and food for wildlife. They absorb carbon dioxide and produce breathable air. And one of the best things about trees is that they add to the beauty of the ancient pine from California White Mountainsworld.

Here are some of our favorite tree facts, enjoy!

1. Trees are the longest living organisms on Earth, and never die of old age. The Old List is a database of ancient trees that officially tracks old trees, their species, and location. Methuselah, from California’s White Mountains, comes in at over 4,800 years old.

2. Just like humans, trees need water to survive--and they drink a lot of it. In a single day, a large tree can consume 100 gallons of water out of the ground and discharge it into the air as oxygen and water vapor. Keep in mind that many conditions play a role such as the size of the tree, species of the tree, humidity, temperatures, sun exposure, etc.

3. Strategically planting trees and shrubs can save you up to 25 percent on your energy bills. Not only do they provide shade in the summer, but serve as a windbreak in the winter, too. (Get more information on smart landscaping.)Moon Tree

4. “Moon trees” were grown from seeds taken to the moon in early 1971. After orbiting the earth with the Apollo 14 mission, these tree seeds returned to earth and were germinated by the Forest Service. After being planted with their earth-bound counterparts, these seedlings showed no discernible difference after twenty years of growth.

5. 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.

6. Pine cones have genders. Male pine cones shed pollen and female pine cones make seeds. When the wind blows pollen into the female cones, you guessed it, the seeds become pollinated.

7. The "knock on wood" tradition comes from a time when primitive pagans used to tap or knock on trees to summon the protective spirits that resided in them.

8. A tree can absorb as much as 48 pounds of carbon dioxide each year and can sequester 1 ton of carbon dioxide by the time it reaches 40 years old. It is estimated that United States forests absorb about 10% of the country’s CO2 emissions each year.

9. Trees can help you find your way if you get lost in the woods. In northern temperate climates, moss will grow on the northern side of the tree trunk, where there is more shade. Also, a tree’s rings can help point you in the right direction too. If you’re in the northern hemisphere, you can see the rings of the tree grow slightly thicker on the southern side since it receives more sunlight. In the southern hemisphere, the opposite is true, with rings being thicker on the northern side.Map of the world showing which continents pine trees grow on.

10. Pine trees grow on six of seven continents, with Antarctica being the only one left out.

11. Trees lower air temperature by evaporating water in their leaves.

12. If a birdhouse is hung on a tree branch, it does not move up the tree as the tree grows.

13. Trees improve water quality by slowing and filtering rainwater and protecting aquifers and watersheds.

14. The different parts of a tree grow at different times throughout the year. Typically, most of the foliage growth happens in the spring, followed by trunk growth in the summer and root growth in the fall and winter.
