Samoa

The islands of Nu'utele and Nu'ulua have been identified as highly significant sites for conservation in Samoa. They hold large populations of species currently found nowhere else in the country' including threatened land-birds, seabirds and nesting

1. During a recent survey around Upolu, Savaii and Nuutele the Yellow Crazy Ant was both observed and collected as samples in different locations.

To determine the top 20 manageable invasive plants in Samoa and to then prioritises the work that needs to be done to manage them effectively. The workshop will aim:

The Aleipata islands are considered to be of great regional conservation significance because they are uninhabited (with the exception of Namua), relatively pristine as forest ecosystems, hosting many species threatened throughout the greater Samoa, and still not invaded by most invasive alien species (IAS) present within Upolu main island. Due to this reason they were included in the list of the 7 key biodiversity areas of Samoa (Conservation International et al. 2010).

Lack of biological knowledge of invasive species is recognised as a major factor contributing to eradication failure. Management needs to be informed by a site-specific understanding of the invasion system. Here, we describe targeted research designed to inform the potential eradication of the invasive yellow crazy ant Anoplolepis gracilipes on Nu'utele island, Samoa. First, we assessed the ant's impacts on invertebrate biodiversity by comparing invertebrate communities between infested and uninfested sites. Second, we investigated whether an association existed between A.

Many ant species that have been accidentally spread throughout the world have significant economic, environmental and social impacts in areas that they now infest. One of the most notable invasive ants is the Yellow crazy ant, A. gracilipes, and this species is present in Samoa, including on the Aleipata islands. The Aleipata islands are considered to be of great regional conservation significance because they are uninhabited, relatively pristine, contain many species threatened throughout greater Samoa, and lack many exotic species present within greater Samoa.
