Yellow crazy ant

The Samoan islands of Nuutele and Nuulua from part of the Aleipata Marine Protected Area, in recognition of their contribution to biological diversity in Samoa. In a 1986 review of 226 islands in the South Pacific region, these islands together rated 30th in importance for biological diversity. The islands provide essential habitat for a reange of sea birds, bats and land birds such as the rare friendly ground dove, sea turtles, shell fish and other marine life.

While invasive species eradications are at the forefront of biodiversity conservation, ant eradication failures are common. We reviewed ant eradications worldwide to assess the practice and identify knowledge gaps and challenges. We documented 316 eradication campaigns targeting 11 species, with most occurring in Australia covering small areas (b10 ha). Yellow crazy ant was targeted most frequently, while the bigheaded ant has been eradicated most often.
