Moku'au'ia (Goat Island)   18 Jul 2007

Trip Goal: To assist DOFAW biologists in an attempt to eradicate Yellow Crazy Ants from the islet using Mokoli'i Islet as a control (no bait used). Using the results of our bait preference trials, a new bait was made specifically for controlling Yellow Crazy Ants in Hawai'i. This ant species has disrupted seabird colonies and ecosystems elsewhere in Hawai'i and around the tropics, but eradication has been troublesome. A successful eradication on Moku'auia would be great step in restoring these fragile island ecosystems to their natural state.

Accomplishments: Over the course of 3 months, we completed 2 ant bait applications and conducted intensive monitoring of the ant and seabird populations. We were able to significantly reduce ant numbers, but not eradicate them entirely. However, as a result of our experiment, seabirds were able to survive and successfully hatch chicks on the island. No seabird chicks survived on our control islet (Mokoli'i), where ant bait was not applied. More importantly, we have learned from the project and will readjust the bait amounts and timing and will hopefully eradicate the ants soon.

Intern Account: Malia:
"This trip was plagued with surprises, all of which were not good for the seabirds. The ant population which has been fluctuating during the past trips has continued to remain unstable. The spot where we had found a nest earlier is still sparsely covered with ants, although there seem to be new nest being developed. We found about a hundred ants in an area near the old nesting area. This area did not have ants before. While running the transect, we discovered that the north side of the island seemed to be ant-less until the very eastern part near the naupaka bushes. However, while picking up the ant cards, there seemed to be more ants than the last time. The dry areas on the west side of the island had no unusual ant life. Unfortunately a dog has been swimming out to the island and killing the seabirds in their burrows. The seabirds have no chance to fly away from the dog because the dog corners them in their burrows. Two dead birds were spotted this week. Although better than the six dead birds spotted the week before, a trap has been set out to catch the dog and prevent any further seabird killings. A new ant bait was set out on the islet last week, so I hope that the new bait brings the rising ant population down."
