Abstract
Kunigami-village, Okinawa, is a core habitat of endangered species and I have analyzed the forest age distribution using the forest register. Before this analysis, I corrected forest compartment maps, many of which had lost the subcompartment numbers linking them with the forest register. In this study, Matured forests are found in the more innermost depths and on the east side of the area. However, some of them were lost after Okinawa's reversion to Japan in 1972. Many forests were renewed from the mid-1920 to 1930s in addition to those in the 1950s which are well-known. Almost all of the forest has been impacted by humans. Matured forests are important and we have to protect them. Conversely, we have to study past human impacts to improve forest operation so as to live with endangered species in second growth forests. The forest register is an important tool to manage that.
