Options
  • The Alerts Report is an online information source from where trends in waterbird numbers on protected areas can be obtained.


    •
  • The Alerts System identifies species that have undergone major declines in numbers and flags these species by issuing an Alert.


    •
  • Trends are assessed over the short-, medium-, and long-terms (5, 10 and up to 25 years respectively) and also since site-designation. If declines exceed 50%, then a High-Alerts is issued and if declines exceed 25% then a Medium-Alert is issued.
