Rare and Priority Plants of the Pilbara is a field guide and identification tool for the 167 Threatened and Priority flora known from the Pilbara bioregion, including species not yet recorded from the region but likely to be found there. In addition to those that have been scientifically named, it also covers taxa that have not yet been named and are listed on the Census of Western Australian Plants under phrase names. It includes all species currently listed as conservation taxa by the Department of Parks and Wildlife.

Developed as a collaborative project between Rio Tinto Australia and the Western Australian Herbarium, Rare and Priority Plants of the Pilbara provides the most comprehensive and up-to-date information available on these rare and important plants, and will provide a useful guide for environmental consultants, botanists, industry environmental officers, conservation planners and others with a need to understand the flora of the Pilbara.

Each species is represented by a profile page including vernacular name, a botanical description, spotting features, and notes on ecology and distribution. All species are illustrated with the best available images, and current distribution is mapped. Species profiles can be accessed by taxon name and filtered by botanical family or using simple features such as habit, flower colour and habitat.

Note that Rare and Priority Plants of the Pilbara is not a complete identification key to the plants of the Pilbara. In some cases, rare taxa may look similar to common ones; nevertheless, by carefully comparing a specimen with the information provided, including the images, distribution map and botanical description, most species should be able to be discriminated accurately and effectively.

All information is packaged in the app, allowing Rare and Priority Plants of the Pilbara to be used in the field in remote localities without web connections. This means that the app is a large download; depending on connection speed, it may take several minutes to download.
