WeBS Report Online

The WeBS Report Online interface allows the viewing of both the latest and historical data for both WeBS Alerts, and the Annual WeBS Report.

Read on to help understand the information available and how the reports were produced.

Each area or 'tab' of the interface returns data available after you select a species or location to filter by.

WeBS Alerts

The WeBS Alerts report is a triennial report that is part of the BTO research report series. The results of the report are represented by the WeBS Alerts tab in the WeBS Online Report interface. 

The purpose of Alerts is to indicate the status of waterbirds on two types of protected sites - SPAs (Special Protection Areas) and SSSIs (Sites of Special Scientific Interest), that are designated for their waterbird features.

Annual Report

The WeBS Annual Report, is represented in the WeBS online Report interface as two areas (or 'tabs') - 

Numbers & Trends

The Numbers & Trends element of the interface represents the information previously available only as the paper report Waterbirds in the UK. The interface adds the opportunity to see more data, scroll back through time  and see the mean change according to the five years on display while retaining a comparison with the current five-year average sort data within each year.

Low Tide Counts

Maps showing counts of key species for estuary locations only.

Select a year for the count data after choosing a location to return a table with available species maps to select.

Grey shapes on Low Tide Count maps indicate areas that weren't counted in that particular year.  Two different shades of green shapes are used – for intertidal and subtidal areas.
