Black Holes

Suffolk Butterfly Recording 2017- "Black-Holes"

In my recent 2017 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- 2016, this being the first two 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 2017 to increase butterfly species coverage for Suffolk. 

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

TL74-Area West and North of Clare

TL95-Area South of Bradfield villages

TM16-Area North and West of Debenham

TM17-Area East of A140

TM26-Area North & West of Framlingham

TM27- All areas

TM37-All areas other than Halesworth town

TM38- Area bordering A144 and B1062

TM 48- Area between A145 and B1127

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
