Black Holes

Suffolk Butterfly Recording 2019- "Black-Holes"

In my recent 2019 letter to butterfly recorders (click here for text)  I promised you details of the areas of Suffolk in which no butterflies were found during the period 2015- 2018, this being the first four years of the current five-year recording period for the Butterflies of the New Millennium recording scheme.

Below is a map of the Suffolk recording area which shows the areas without any butterfly records i.e. "black-holes" that exist, these are shown by the dark- blue spots.

Targets for specific recording

A list of the actual "black-hole" tetrads (2x2km squares) is given below and I would ask you all to try and visit as many of them as you can in 2019 to increase the overall butterfly species coverage for Suffolk. 

Based on the above map the following tetrads in the table below should be visited in order to increase county coverage.  2019 represents the final year of the current five-year recording period for the Butterflies of the New Millennium recording scheme so this is an incredibly important year

Please note that access to some may be restricted due to the land being private or there may be no suitable footpaths.  In addition, some involve inland waterways, are tidal or may simply be totally unsuitable for butterflies

However, in order to assist you with targeting key areas the following 10km squares are those which require significant recording coverage

The Old Black Hole Map

The previous map showed an OS map of Suffolk overprinted to show the density of records for the period 2010 to 2013.  This is still available but we have been unable to produce the latest map in this way.  To see the old map  Click here and the map will open in a new window or tab
