When species are listed as threatened, they become better protected by legislation. Significantly more resources are given for their preservation and development proposals that affect them are scrutinised in more detail.

Conservation listings are reviewed regularly to make sure they are accurate and appropriate. Ecological Associates was engaged to collate and review all available information for a range of plants and animals including Ampurta, Thick-billed Grass Wren, Krefft's Tiger Snake and Pearson's Island Rock Wallaby.
