The result of a fifty year period of “experimental forestry” in the area, these rings of Japanese cedar trees are the result of a scientific trial that aimed to measure the effect of tree spacing on growth. The experiment was undertaken by planting trees in 10 degree radial increments, forming ten concentric circles of increasing diameter. From the aerial shots of the forest, the effect of tree spacing on growth seems immediately apparent—both of the rings have grown to have a concave shape; the trees increase in size the further from the center they are.
