The Upper Thames Branch of Butterfly Conservation have produced an excellent Atlas of Butterflies in Berkshire, Buckinghamshire & Oxfordshire.
Nick Boles, the chairman of Upper Thames Branch of Butterfly Conservation has stated “We were pleased to include your organisation in the acknowledgements. MKNHS provide very important records (often through BMERC) and we would struggle to accurately reflect the situation in MK without those records.” So we can clearly see the benefit of the tetrad records that we have been maintaining.
If you are not already a member of Butterfly Conservation, you can join from £32 a year or £2.66 per month. Once enrolled with Butterfly Conservation, you will receive a copy of the Atlas if you join the Upper Thames Branch.
Alternatively, you can purchase a copy of the Atlas from Diane Garland, Butterfly Conservation, Manor Yard, Lulworth, Dorset BH20 5QP at £10 plus £1.60 p&p.
