BLACK HAIRSTREAK (SATYRIUM
PRUNI) ACTION PLAN
Lead Agencies Public Sector English Nature
Voluntary
Sector The Wildlife Trust
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.
