This map shows the observed distribution of the Great Cormorant for 2017.
The red circles are the grid cells where Great Cormorant have been reported.
The transparency of the red circles indicate how many surveys sheets were submitted for that grid cell; the darker the red the more reliable the data. Of the 315 grid cells with reports, 83 had only one sheet; an example is grid number A11.
The size of the circle represents the reporting rate. The maximum reporting rate for Great Cormorant was 20.0% (eg grid number F10) and the minimum was 0.3% (eg grid number Z1).
This map shows the observed distribution of the Great Cormorant for all years.
The red circles are the grid cells where Great Cormorant have been reported.
The transparency of the red circles indicate how many surveys sheets were submitted for that grid cell; the darker the red the more reliable the data. Of the 703 grid cells with reports, 55 had only one sheet; an example is grid number B5.
The size of the circle represents the reporting rate. The maximum reporting rate for Great Cormorant was 100.0% (eg grid number B5) and the minimum was 0.1% (eg grid number L15).
This map shows the breeding distribution of the Great Cormorant for 2017.
