How do I submit survey data to WWT?

How do I find out about the latest status of a particular waterbird?

In the UK, the official conservation status is provided by Birds of Conservation Concern. Internationally, the IUCN Red List is the main assessment, but most agreements and conventions also have their own prioritisation process (e.g. see table 1 in the African Eurasian Waterbird Agreement document).

Official population estimates, which help to inform status assessments and also provide a basis for 1% thresholds, are provided on Wetlands International’s Waterbird Population Estimates website and, for the UK, by the Avian Population Estimates Panel.

How can I access GSMP data?
