TORII STATION, Okinawa — U.S. Army Garrison Okinawa recently celebrated the successful eradication of the Browsing Ant during a Government of Japan, Ministry of the Environment (GOJ MOE), led press conference near Naha Military Port (NMP), May 23.<\/p>\n

The eradication highlighted the importance of cross-organizational collaboration between USAG Okinawa and the GOJ MOE.<\/p>\n

\u201cUnlike humans, plants and animals do not have physical boundaries. They could easily come and go on roads and through utility pipes, so establishing a cooperative relationship with local stakeholders is key for success,\u201d said Naho Ishiki, Directorate of Public Works, environmental engineer.<\/p>\n

The Browsing Ant, an invasive alien species (IAS), was first observed on Okinawa Island in February 2020. The species is listed on the Japan Environmental Governing Standards, requiring eradication from installations upon discovery.<\/p>\n

\u201cInvasive species can be very destructive and hurt native species, so invasive species control helps us protect and preserve viable populations of endangered species, native communities and landscapes,\u201d said Ishiki.<\/p>\n

Immediately following the first detection a cooperative control team of scientists, comprised of researchers from local universities and municipal offices, was established with the goal of eradicating the ants through information sharing.<\/p>\n

In response to the notification from GOJ MOE, USAG Okinawa conducted an invasive ants distribution survey in June 2020, confirming their presence at over 100 locations on NMP. \u00a0NMP is vulnerable to the introduction of IAS since various types of cargos and vehicles are continuously transported into the area.<\/p>\n

\u201cGiven the high mobility of these ants, it was important to take cooperative measures both on and off base,\u201d said Ishiki. \u201cUSAG Okinawa\u2019s control project employed the latest research findings, managing to use unprecedented control techniques while complying with DoD and Army regulations.\u201d<\/p>\n

Control methods needed to be environmentally friendly as NMP is a breeding and resting site for the Little Tern, a JEGS-listed Species at Risk, and other migratory birds subject for conservation. At the time, suitable control methods for the Browsing Ant were not known or established in Japan yet.<\/p>\n

Control efforts were initiated in April 2021 and continued monthly. Four months after applying the baits in August 2021 the number of the ants drastically decreased.<\/p>\n

Currently, the population of the ants at NMP has been greatly reduced. Though continuous monitoring and controlling are still necessary to eradicate the species, USAG Okinawa has achieved near-zero detection for the past two years.<\/p>\n

\u201cUSAG Okinawa managed to establish a project, fund it to reach the lead researcher(s), conduct a distribution survey of the target species all within a year,\u201d said Ishiki. \u201cThis achievement could be a model case as it demonstrates the importance of early detection, early response and cross-organizational collaboration in the fight against invasive alien species,\u201d said Ishiki.<\/p>\n

Currently, the population of the ants at Naha has been greatly reduced from its original numbers. Though continuous monitoring and controlling are still necessary to fully eradicate the species, the ongoing effort has achieved near-zero detection for the past two years.<\/p>\n
