3 Interesting Facts about Trees
Some trees have been to the Moon.
In 1971, during the Apollo 14 mission, “Moon trees'' were grown from seeds taken to the Moon, as NASA wanted to see if the trees will grow differently back on Earth, because of the Moon’s orbit. These trees were donated to state forestry services in 1975 and 1976.
Trees are able to communicate and defend themselves against attacking insects.
When trees are invaded by insects, they produce some chemicals called phenolics. They can also signal danger to other trees so they can start their own defense. Willow trees, for example, emit certain chemicals when they’re attacked by webworms. Other willows then produce more tannin, making their leaves harder for the pests to digest.
Trees help to reduce stress.
Research suggests that being around trees is good for our mental and social well-being. They found that the denser the forest, the lower the stress! Trees release chemicals called phytoncides that when we breath them in it can reduce blood pressure, lower anxiety levels, and increase pain threshold.
