アマミノクロ� �サギの調査結� ��.pdf

The Amami rabbit monitoring survey is conducted on Amami-Oshima and Tokunoshima islands. The survey includes a common investigation on both islands and unique investigations on each island. The survey items include fecal pellet surveys and sensor camera surveys.

On Amami-Oshima, the fecal pellet survey has been conducted since 2005, and the results show an increase in fecal pellet frequency in each area, particularly in area E. The sensor camera survey has also been conducted since 2007, and the results show an increase in the number of shooting locations and shooting rates.

On Tokunoshima, the fecal pellet survey has been conducted since 2006, and the results show an increase in fecal pellet frequency in the northern and southern parts of the island. The sensor camera survey has been conducted since 2012, and the results show an increase in shooting frequency in both the northern and southern parts of the island.

The results of the surveys suggest that the population density of the Amami rabbit is increasing on both islands, possibly due to the progress of mongoose control measures on Amami-Oshima and cat control measures on Tokunoshima.
