In Japan, Black Rat Rattus rattus eradication programs have been carried out recently in the Ogasawara (Bonin) Islands (Hashimoto 2009, Makino 2009). The Ogasawara Islands are known to be a sanctuary for birds, including several indigenous or endangered species such as Columba janthina

In Japan, Black Rat Rattus rattus eradication programs have been carried out recently in the Ogasawara (Bonin) Islands (Hashimoto 2009, Makino 2009). The Ogasawara Islands are known to be a sanctuary for birds, including several indigenous or endangered species such as Columba janthina nitens, Apalopteron familiare, Tristram’s Storm-Petrel Oceanodroma tristrami, Matsudaira’s Storm-Petrel O. matsudaira and Bonin Petrel Pterodroma hypoleuca (Chiba 1992). However, they are threatened by invasive mammals such as Black Rats, Norway Rats R. norvegicus and feral cats Felis catus (Kawakami 2002, 2008). Based on historical documents, Yabe (2006, 2008) estimated that Black Rats were introduced into the Ogasawara Islands in the 1910s,...

Notably, the number of damaged crop species substantially varied among the prefectures, possibly due to differences in terms of the extent of countermeasures against crop raiding by macaques. To discuss the regional variation in the preference for specific crop species, quantitative and qualitative data should be standardized among the prefectures. The information on the crops damaged by macaques is generally retrieved from government reports, which are only retained for a short period; therefore, digital archiving is necessary for their future use. In addition, we discuss future challenges about the use of information on the diet of crop-raiding macaques. Moreover, we emphasize the importance of collaboration between researchers of fundamental and applied research.
