Introducing the IUCN Red List
Red: a colour of alarm, urgency, passion and energy. For most conservationists, “The Red List” evokes all four of these feelings, perhaps all at once. The Red List tells us which species are most in danger and which to conserve first. It is also a powerful tool for persuading governments to protect threatened species, and for most of the plant and animal species worldwide, it is vital. The Red List is nicknamed the “barometer of life”, for it is a rich compendium of information on the threats to species, their ecological requirements, where they live, and information on conservation actions that can be taken to reduce their risk of extinction.
In full, it’s called The IUCN (International Union for the Conservation of Nature) Red List of Threatened Species TM, and BirdLife International is the authority for birds, coordinating the process of evaluating all of the world’s bird species against the Red List categories and criteria in order to assess their extinction risk.
It’s much more than a list, however. It’s the culmination of decades of work, efforts from thousands of people, reports from the field, production of scientific papers, countless calls, emails, and discussions on BirdLife’s Globally Threatened Birds Forums. Those that contribute are an army of ornithology experts: from professionals studying specific species, to bird tour guides who notice changes day-in and day-out; from local and national NGOs (such as BirdLife Partners), to seasoned conservationists with a regional or global perspective; and in a few cases, the only people who can access very remote areas and have been lucky enough to see particularly rare species.
To assign each species to a Red List category, the BirdLife Global Science Team assesses the size and trend of its population and geographic range, and compares this to the IUCN Red List Criteria. Doing this objectively and consistently across all species ensures reliable, comparable assessments that hold up globally.
Every year, the team burns the candle at both ends to reach conclusions about the state of the world’s birds, assessing a portion of the globe’s 11,000 + bird species, with a more extensive overhaul every four years. Every time, scores of bird species are moved to higher or lower categories of threat.
The Red List is one list that you do not want to be at the top of, however. A species being “uplisted” means that it is at greater risk of extinction, and that is happening all too often. But more than showing an observed change on a barometer, a bird species reaching the threshold for “globally threatened” means that BirdLife is officially ringing a great big red warning bell from the roof. As conservationists, we are alarmed and called to action by an uplisting; and we celebrate and learn lessons from a “downlisting” – an event that, pleasingly, is more common than you might think, thanks partly to the dedicated work of BirdLife Partners around the globe.
Below, you will find stories of the “ups” and “downs” of the past few years. But don’t forget that in the Anthropocene – the so-called geological age of human impact – a downlisting does not mean “saved”, but only one step on the road to recovery, and that more species are still heading the wrong way.
