"Monster Wolf," a repellent device installed in a demonstration experiment to prevent wild boars from damaging crops = Suetomo, Oyabe City
Oyabe City introduced a wolf-like repellent device as a countermeasure against agricultural damage caused by harmful birds and animals such as wild boars, and embarked on a demonstration experiment to repel them with threatening sounds and lights. The device will be installed in the hilly and mountainous Suetomo area to explore its effects, and lead to countermeasures against the aging of human resources responsible for exterminating harmful birds and beasts, as well as reducing the burden of maintaining and managing electric fences. ●First introduction in the prefecture The repelling device "Monster Wolf" is about 120 cm long and about 80 cm high, and detects when wild animals approach with an infrared sensor. While flashing the light-emitting diode (LED) lights in its eyes, it shakes its head from side to side and emits a threatening sound such as a wolf's cry. According to the city, it is being used in about 60 locations nationwide, and it is believed to be the first time it has been introduced in the prefecture. It is expected that wild boars will mistake them for their natural enemies, wolves, and their defensive instincts will make them shy away from them. There are more than 80 types of threatening sounds, such as howls of beasts and gunshots, to prevent animals from becoming accustomed to sounds. Recorded sound sources can be added, and the voice of Mayor Morio Sakurai yelling, "Go back to the mountains, this is not where you come from." In the Suetomo district, 43 wild boars were captured in 2019, 13 in 2020, and 11 this year (as of August). According to local residents, it seems that there are a certain number of individuals that are not caged, and there are traces of wild boar damage around the fields. The city allocated 600,000 yen as countermeasure costs in the September supplementary budget, and introduced five cameras equipped with infrared sensors in addition to repelling devices. Installed around the device, the behavior of wild boars captured by the camera will be verified, and the effect on bears and deer will also be investigated. If the effect can be confirmed, the plan is to relocate the system to other districts to spread the ``repulsion effect'' throughout the city. I want to put a system in place."
