Brown Hairstreak Survey Methods Workshop

For anyone interested in the Brown Hairstreak, there is a national survey methods workshop at Ruishton Village Hall near Taunton, Somerset on Saturday 23rd February 10:00-15:00. The aim of the workshop is to devlop and test a new method for surveying Brown Hairstreak abundance through egg counts. It is hoped that this will become the standard method so that egg counts can increasingly be used to report on the species national population status through the UK Butterfly Monitoring Scheme (UKBMS). Currently, only adult counts from transects (usually of very low numbers) are used in the UKBMS.

The workshop is open to anyone who wants to learn more about Brown Hairstreak egg count methods or wishes to help shape method development. The day will comprise of a series of presentations on methods used in existing surveys, proposals for a new standardised approach with associated discussion, picnic lunch, followed by searching for the eggs and testing the method out in the field (Brown Hairstreak occurs nearby). The workshop is free and tea, coffee and biscuits will be provided.

If you intend to come along, please drop Tom Brereton an email at tbrereton@butterfly-conservation.org or call 01929 406019 (mobile: 07816 786173).
