GPS aids mapping boundaries of ant colonies

Researchers in Arnhem Land in the Northern Territory, Australia have mapped 90 colonies of the invasive yellow crazy ant. The mapping is part of a joint eradication program involving traditional owners, the Northern Land Council, the CSIRO and the Territory Government. Researchers are expecting to find more than 100 colonies of the exotic pest. The mapping is necessary so they can start eradication soon.

GPS is being used for mapping the boundaries of the super colonies. The biggest one is 83 hectares so far and the researchers are just putting the GPS around the edge so that in the future when they start doing the treatments, which will be by helicopter, they can download the GPS data into the helicopter. Then the helicopter will have an accurate map of where it needs to fly and the whole area can get treated.
