Surely you have already seen images of crop circles, those patterns that appear again and again in cereal fields in the summer months. But did you know that in Japan there are even trees that have grown in perfect circles?
While there are still wild speculations about the formation of crop circles, the explanation for Japan’s tree circles has long been known – conspiracy theorists, alien fans and esotericists will be disappointed. It is quite simple – it’s just science. They are the result of a forestry experiment that began in 1973.
A research forest was established in 1973 near Nichinan, Japan. Among other things, the question here is how the growth of a tree depends on the planting density. Around 45 years ago, employees planted Japanese cedars (Cryptomeria japonica) in ten concentric circles spaced ten degrees apart.
What is even obvious to the layman at first glance: Those trees that have the most space (in the outer circles) have a much larger crown than those that are crowded in the inner circles. Investigations will now show if and how the growth of the trunk is affected.
The trees are due to be harvested in about 5 years but officials are now considering preserving the crop circles. For those who are interested, here are the exact coordinates. Have a look 😉
