We will explore Holling Grange Dingle near Abbey Dore in south-west Herefordshire. The brook cuts a steep section through limestone at SO c.370314, where we hope to find alternating bands of calcareous and more acidic substrate and a corresponding variation in bryophyte species. There is woodland too, with some old trees (including Small-leaved Lime) for epiphytes.

Park at The Meadowlands (SO 361318) which can only be reached from the south-west, via the minor road from Abbey Dore to Newton.
