Defenders of Wildlife has developed a method to score the status of threats a species faces and the species' biological (i.e., demographic) status. The scores can range from -1 (threats are worsening / demographic status is deteriorating) to +1 (threats are ameliorated / demographic status is improving). Here we show how these scores can be presented to provide a quick overview of status, but these are not real estimates of the species' status. See our PeerJ paper for more details.
By extracting past scores we can better understand how the species has fared - in terms of both threat and demographic changes - over an extended period. These data are for illustration only, but will provide much-needed information when dynamic recovery plans are fully implemented.
