Deer
The deer population has rapidly increased on Kuchinoerabu-jima. This has had adverse effects on agriculture and vegetation levels of evergreen broad-leaved forests. In order to better grasp the situation, the Kuchino-Erabu senior group have begun to estimate the deer population by counting deer along certain routes.
