Distribution map
Distribution - 2017
This map shows the observed distribution of the White-faced Heron for 2017.
The red circles are the grid cells where White-faced Heron 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 White-faced Heron was 100.0% (eg grid number A9) and the minimum was 0.3% (eg grid number K15). 
Distribution - all years
This map shows the observed distribution of the White-faced Heron for all years.
The red circles are the grid cells where White-faced Heron 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 White-faced Heron was 100.0% (eg grid number B5) and the minimum was 0.4% (eg grid number K15).
