Brockadale, Southwest Yorkshire.

Meet in the Brockadale YWT nature reserve car park at SE 513174 at 10:30 h. The car park is 400 yards down Leys Lane, which is half a mile north-west of Little Smeaton on the minor road towards Darrington. Leys Lane is marked with a 'no through road' sign.One of the features of the reserve is its limestone crags. Those within the woodlands may be cool and shaded in part, but the top of the south-facing cliffs with its thin soils bakes in the summer sun and provides a home for the only Yorkshire site for Truncatellina cylindrica. The snail is at present only known from a very small site within the reserve, but it may also occur on several of the other south-facing crags which occur along the valley sides.Full details of this event can be found on the YNU website.
