I put up a post each week on one endangered Australian animal species, but if you’ve ever wondered how they work out which species are more or less endangered, the above small article will give you an idea (it’s from last year).

Here’s another from Qld, which explains it more clearly as it applies for this state. Animals may be on a State list but not be on a National list.
