Meet at the Natural England car park (SU 731966) on the north side of the M40 motorway at 9.30am. Access is signposted from the A40 which can be joined from either Junction 5 or 6 of the M40.
Target species are Silver-spotted Skipper, Chalkhill Blue and Brown Argus. Plants include Chiltern Gentian.
Bring a packed lunch, and stout shoes are recommended as there are several steep slopes.
In the afternoon, if time permits, we will visit the nearby reserve of Whitecross Green Wood for Brown Hairstreak.
There are no facilities at either of the sites visited today.
