Trees are one of my favorite things. They have many dimensions to them, but I did not know the following. Did you?
Most people know that trees near buildings can raise property prices by an average of 14 percent in the U.K. and as much as up to 37 percent in the U.S.
In northern temperate climates, moss will grow on the northern side of the tree trunk, where it is shadier. Failing that, if you find a tree that has been cut down, you can observe the rings of the tree to discover which direction north is. In the northern hemisphere, the rings of growth in a tree trunk are slightly thicker on the southern side, which receives more light. The converse is true in the southern hemisphere.
As well as providing shade, a large tree can also transpire as much as 378.5 liters (100 gallons) of water into the air per day. This has a cooling effect roughly equivalent to 10 single room-sized air conditioning units operating 20 hours a day!
The acorns of oak trees (which don’t usually appear until the tree is around 40 years old) are food for dozens of species, including wild boar (and now more commonly pigs), jays, pigeons, pheasants, ducks, squirrels, mice, badgers, and deer.
Once a tree is attacked, it will “signal” to other nearby trees to also start their self-defense, before they are attacked! Methods of communication include releasing chemicals into the wind and possibly even sending chemical or electric signals through the michorizal network of roots (a network of shared fungus fibers).
