Several thousand non-native IATS of plants and animals have become established in the U.S. and globally. In the U.S., approximately one in seven invasive species impact the economy and together account for more than ~$137 billion a year in losses. Military personnel work hard to limit the movement of IATS, but have limited tools to conduct biosecurity related efforts on deploying and redeploying cargo and craft. Current protocols focus on cleaning using power washers to prevent potentially invasive organisms from affecting agriculture, ecosystems, and animal/plant health. Biosecurity related procedures and organizational responsibilities vary, but in spite of the military’s best efforts, IATS still manage to be transported and arrive at unintended destinations, often with readiness, public affairs, environmental, and financial implications.
Labor-intensive cleaning, surveillance and mitigation methods are somewhat effective, but they are resource intensive and hinder time critical strategic mobility. In spite of interdiction efforts, unwanted organisms successfully transfer and establish themselves outside native ranges. The primary tools used to reduce the probability of transporting invasive organisms include power washers, compressed air, mops, brooms, etc. on metal shipping containers, enclosed cargo, heavy equipment, and vehicles. Depending on destination, glue boards, snap traps, rodent bait boxes, insecticidal dusts, and “No Pest Strips” containing a volatile insecticide. In particularly sensitive areas such as Guam and the Joint Region Marianas Area of Responsibility, all military cargo, equipment, and vehicles in support of operations are cleaned and inspected to strict standards1 prior to movement. In the past, SERDP supported research to control the brown tree snake. This work has successfully transitioned to other agencies and into the field.
Applied research and advanced technology demonstration projects that result in the development of new and greatly improved tools, technological advancements, and biosecurity innovations are needed to prevent the unwanted spread of exotic species through strategic movements of DoD assets.
