A field guide to the birds, mammals, reptiles, and amphibians of the beautiful Yalgorup National Park in Western Australia. It covers 209 species and includes 541 images that will assist with making identifications in the field.

The species lists have been carefully vetted by locals with great knowledge and love of the area. These contributors have also provided a range of identification images to complete coverage of the guide.

To use the guide, drill down though the species groups to find a group that you think is likely to contain the species you have observed. Then you can tap "filter" to see all identification images for species in the chosen group. You can refine the filter via the filter tab, selecting only those species that have the chosen colours. The required accuracy of the colour filter can be adjusted to refine or broaden the number of species that match your search. For groups with size and wingspan data, such as birds, you can also filter based upon size and wingspan estimates.

Once you find an image that matches, view the description details for that species to confirm the identification. Confirm by tapping the + icon to add a new record. Fill out your record details, add a sound recording or photo as evidence, then upload the record to the server so that it can be kept for posterity and shared with others.

The information in this app is the result of collaboration by many contributors. All users of this app are welcome to contribute to the quality of the app by adding descriptive details, identification photos and sound recordings. If you have knowledge that would improve the usefulness of this app. please consider adding it via the Gaia Guide website (http://gaiaguide.info/).
