Simon and Gill continued the egg search yesterday in the area adjacent to the old pond, they added 97 eggs to the count, now showing a total of 555 eggs in the wood itself – map below. The Blackthorn in this area was cut in August 2015 and was in ideal condition for egg laying this summer. The volunteers were cutting the Blackthorn on the edge of the wood on Mr Boaz’s land yesterday. This has had no eggs this year as it was over mature.
Blackthorn cutting is by far the most difficult job we do at Grafton. This year we have had help from WWT roving volunteers which was most welcome The egg count shows how effective this work is to conserve this rare butterfly.
