1       INTRODUCTION

 

The Black Hairstreak butterfly has a highly restricted distribution in Britain, being found mainly in a band stretching from Oxfordshire through to Huntingdonshire. Northamptonshire supports a number of colonies, most notably at Glapthorn Cow Pastures, which was designated an SSSI because of the strength of its Black Hairstreak colony. In recent years many colonies have become considerably weaker, possibly due to changes in climatic patterns.

 

 

2       CURRENT STATUS

 

2.1           International / National Status

 

The Black Hairstreak has a highly restricted distribution in the UK, being limited to around thirty-five colonies in the East Midlands and is listed under Schedule 5 of the Wildlife and Countryside Act.

 

2.2           Local Status

 

Northamptonshire is particularly important for the Black Hairstreak, with a number of colonies being supported in the county’s woodlands. It is not possible to put an accurate figure on the number of colonies – the only recent survey of potential sites, carried out by Estella Roberts of Butterfly Conservation coincided with a very poor year for the species due to a very wet spring.

 

 

3                   CURRENT FACTORS CAUSING LOSS OR DECLINE

 

·         Fragmentation and isolation of suitable stands of blackthorn Prunus spinosa.

·         Unsympathetic woodland management.

·         Clearance of scrub woodland for agriculture.

·         Lack of knowledge of best practise for maintaining colonies in the long-term.

 

 

4                   CURRENT ACTION

 

·         Suitable management is being undertaken on a number of sites in Northamptonshire, including Wildlife Trust Nature Reserves, Country Parks and Forest Enterprise managed woodlands.

·         A seminar was held in 1997 to discuss management practises to benefit Black Hairstreaks.

·         A national survey carried out by ITE in 1999 included a survey of sites in Northamptonshire considered to be potential sites for Black Hairstreak colonies.

·         A monitoring programme has been established at Glapthorn Cow Pastures SSSI by Ioan Thomas.
