Invasive alien species are recognised as one of the leading threats to biodiversity and also impose enormous costs on agriculture, forestry, fisheries, and other human enterprises, as well as on human health. Rapidly accelerating human trade, tourism, transport, and travel over the past century have dramatically enhanced the spread of invasive species, allowing them to surmount natural geographic barriers. Not all non-indigenous species are harmful. In fact the majority of species used in agriculture, forestry and fisheries are alien species.

The purpose of the National Invasive Species Strategy is to minimize the harmful effects of invasive species on the environment and society of Palau through coordination of efforts at all levels of Palauan society, and to facilitate cooperation with neighboring countries and the Pacific Islands region to prevent the movement of invasive species.

Work is based around country visits by the network coordinator to support PILN teams to identify and take strategic action to manage their priority invasive species. The network is functioning by sharing awareness of successful activities being earned out by the teams, providing the mechanism for other teams to do the same, and actively encouraging them to do so.
