    On the map, sketch a polygon or click on a WFD catchment.

    Once you have sketched a polygon or selected a catchment, any enclosed data locations will be automatically selected.
    - To sketch a polygon, click on the Select features by polygon button in the top-left corner of the map.
    - To select data locations by WFD catchment, click on a catchment until it is highlighted in green.
    - To clear your selection, click on the eraser button.

    - Tick this box if you would like to select by more than one catchment.
    - Then click on another catchment to extend your search area.
    - To clear your selection, untick the box or click on the eraser button.
    The list will generate once Step 1 is complete.
    The list will generate once Step 2 is complete. Choose between individual taxa counts or ecological indices.
