A photo taken by drones captures a pair of mysterious circles made of local Obi-sugi cedar trees in Miyazaki prefecture.
NICHINAN, Feb. 3 ― Thanks to drones, the Miyazaki prefectural government captures a pair of mysterious circles made of cedar trees at its forest management site.
Miyazaki prefecture is well-known for Japan’s biggest output of cedar trees and the Nichinan city’s forest is populated by local Obi-sugi cedar trees.
So, the mysterious cycles are in fact the results of a 45-year experimental forestry program by scientists, who planted the local cedar trees to understand the effects of forest density of tree growth, explain prefectural government officials.
The circle of cedar tress has now 69 meters in diameter, and there are 12 rounds of sequence in circles.
