Distribution map
Distribution - 2017
This map shows the observed distribution of the Little Corella for 2017.
The red circles are the grid cells where Little Corella 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 H2.
The size of the circle represents the reporting rate. The maximum reporting rate for Little Corella was 100.0% (eg grid number H2) and the minimum was 0.6% (eg grid number K10). 
Distribution - all years
This map shows the observed distribution of the Little Corella for all years.
The red circles are the grid cells where Little Corella 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 A12.
The size of the circle represents the reporting rate. The maximum reporting rate for Little Corella was 35.5% (eg grid number Z1) and the minimum was 0.3% (eg grid number F18).
