Distribution map
Distribution - 2017
This map shows the observed distribution of the Grey Teal for 2017.
The red circles are the grid cells where Grey Teal 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 A9.
The size of the circle represents the reporting rate. The maximum reporting rate for Grey Teal was 100.0% (eg grid number A9) and the minimum was 0.2% (eg grid number J12). 
Distribution - all years
This map shows the observed distribution of the Grey Teal for all years.
The red circles are the grid cells where Grey Teal 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 S27.
The size of the circle represents the reporting rate. The maximum reporting rate for Grey Teal was 100.0% (eg grid number S27) and the minimum was 0.2% (eg grid number J15).
