Sites for National Grid Square: SN

The map below shows sites for this grid square, each represented by a pin that, when clicked, will show the species at that site. The Grid References provided in the table below the map can be used on Ordnance Survey maps, or on a website such as www.streetmap.co.uk. This is currently more accurate than the Google Map rendering you see below (which is up to 200 metres out).

The Grid Square represented by this map is often divided into squares of 10 kilometres each, numbered 0 to 9 from the south west corner, in both an easterly and northerly direction. This allows a Grid Reference such as SU32 to be specified (where SU is the National Grid Square, 3 is the easting and 2 the northing). Further division gives a more detailed reference, such as SU317201 (where SU is the National Grid Square, 317 is the easting and 201 is the northing).

  
  

Distribution data (2000-2009) has been made available through the generosity of Butterfly Conservation. Any subspecies distribution is taken from the book British and Irish Butterflies, by Adrian Riley. Based on this data, the following species and subspecies may be found in this grid square:
