Guam Invasive Species
Emerging technologies offer new hope in the fight against invasive species. From drones that can spot small infestations to genetic detection methods that reveal hidden pests, innovation will play a key role in protecting Guam’s biodiversity.
Unmanned aerial vehicles (UAVs) are increasingly used to monitor and manage invasive species. Drones can access remote forests and clifflines, capture high‑resolution imagery and even apply baits or herbicides in precise locations. A recent review highlighted how drones expand access, improve mapping and enhance safety compared with traditional methods.
eDNA sampling involves collecting water, soil or air samples and analysing them for genetic traces of target organisms. This technique can detect invasive species at very low densities, long before they are visible. For Guam, eDNA could provide an early warning system for new species arriving via ballast water or cargo.
Machine learning algorithms can automatically detect invasive species in photographs, satellite imagery and acoustic recordings. AI systems help classify species, predict spread patterns and prioritise control efforts. Incorporating AI into drone platforms and smart traps could accelerate response times.
Biological control, the use of natural enemies to suppress pests, is becoming more targeted. Researchers are exploring additional viruses and parasitoids to manage the coconut rhinoceros beetle, and new predators of cycad scale. With proper risk assessments, biocontrol can provide long‑term, self‑sustaining pest suppression.
Technological solutions must be paired with human engagement. Smartphone apps allow people to report invasive species sightings, upload photos and receive feedback from experts. Citizen science projects can crowdsource data collection and increase public awareness. Schools and youth groups could adopt monitoring sites, using drones or sensors to collect data and contribute to research.
By combining cutting‑edge tools with community action, Guam can create a resilient early detection and rapid response network that protects the island’s natural heritage.
