Distribution map

Distribution - 2017

This map shows the observed distribution of the Fairy Martin for 2017.

The red circles are the grid cells where Fairy Martin 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 F5.

The size of the circle represents the reporting rate. The maximum reporting rate for Fairy Martin was 100.0% (eg grid number F5) and the minimum was 0.1% (eg grid number K13).
