Hi Brook, thank for your feedback about the maps in our Field Guide to Victorian Fauna
app.The data for our maps is sourced from the Atlas of Living Australia
and is based on specimens held in Australia’s museums as well as human observations. We acknowledge that these maps sometimes underestimate the actual distribution of species. Ironically this is particularly a problem for common and feral species as they are underrepresented in museum collections and the public are less likely to report their occurrence to us.
We are in the process of replacing some of the maps (those that are a particularly poor representation of a species’ range) with custom-drawn maps (that accurately represent a species’ range). We replaced many of the fish maps in the last update and we will replace others as we receive feedback such as yours. The Red Fox and feral deer maps are now on the list of maps to replace and you should see new maps in the next update. Thank you for helping us to improve the quality of our Field Guide app.
