Search and select a species by the english or scientific name then click 'Map'.

The blue square represents a tetrad (2x2km) and when you click the map a tetrad sized square will be highlighted. To the right of the map you will be told the grid reference of where you clicked, the tetrad name, plus the year the species was last seen there.

Click 'Satellite' on the map to use satellite or aerial photos as the backdrop.  Use the ' + ' and ' - ' symbols to zoom in and zoom out.  Click and hold the map to move around.

You can also zoom to a postcode or place using the search window.

To create a link to that specific place click 'link to this map' at the bottom of the map then copy the web page address from the address window at the top of the screen.
