Big tree

Oldest

Suzuki (1997) studied this species on Yakushima Island. He cites his own previous work (Suzuki and Tsukahara 1987) in having found a tree stump with 794 rings on Yakushima. He also cites other previous workers as having derived ring-counted ages of 685 years on Ullung Do Island, Korea (37.500°N, 130.833°E), and 639 years on Mt. Oninome, Miyazaki, Japan (32.700°N, 131.533°E).

Dendrochronology

I can find (1999.02) only two studies, both dealing with tree demography (Suzuki 1980, Suzuki and Susukida 1989).
