Conservationists are systematically surveying atolls in search of invasive and native ant species.
Ants are some of the best hitchhikers in the world. – Conservation biologist Dr. James Russell
In an age of increasing globalization and mobilization, transportation of invasive species–intentional or not–has become an urgent problem. Even the smallest of invasives can cause profound ecological damage. Ants, which are carried across borders via potted plants, have colonized swaths of mainland and entire islands. The Channel Islands, Hawaii, and atolls throughout the Pacific are a few of the many habitats changing under the influence of invasive ants.
There is good news, however. Scientists are developing tools and methods for removing invasive ants from island ecosystems. Dr. James Russell, conservation biologist and regular writer for National Geographic, is on a mission to systematically survey ants on Tetiaro Atoll and its surrounding motu (islands) in the Pacific. Russell explains:
On each motu we set-up pitfall traps across the motu to maximize spatial coverage as much as possible, and also undertook visual surveys to identify ants. Where time allowedm bait cards were also used to attract ants into the open.
Dr. Russell’s research will inform biosecurity policies and conservation actions to prevent further spread of the invasive ant species. Conservationists have successfully cleared Tiritiri Matanga Island in New Zealand of invasive ants. Russell adds:
If we are really lucky, we may even find a rare potentially native ant species in this far-flung corner of the Pacific.
Strong biosecurity policy can support native wildlife and global biodiversity. Preventing the further spread of invasive species is an excellent and proven way to take care of the natural environment.
