Some creatures rely on having crystal-clear fast-flowing water, yet others need their wetland home to be dry for most of the year. Some have been taken to the brink of extinction by human-introduced predators against which they have no defence, while others seem to be struggling to adjust to our changing climate.

Although it is clear that action is needed for threatened species, it may be far from clear how, when and where we should act. 

The art of saving species is built on firm scientific foundations. WWT works on the principle that conservation action should follow research – that helps us to understand both why a species is rare and which actions will be effective.
