Hawkley Warren
Hawkley Warren (grid reference SU730284) is a woodland on the northeast-facing Wealden Edge, near the village of Hawkley, three miles north of Petersfield in Hampshire. The site is situated in a deep chalk combe.
The site is owned by Hampshire County Council and managed as a nature reserve jointly by the council and Hampshire and Isle of Wight Wildlife Trust. The woodland glades are kept open by coppicing.
Site description
[edit]Beech is the dominant tree at this site although on some of the steeper slopes, Yew dominates; on the deeper soils in the valley bottom the woodland has a more open canopy of Ash and Hazel.
Botanical interest
[edit]The site's primary interest lies in the fact that it is one of three sites in Britain where Red Helleborine Cephalanthera rubra remains; this orchid grows on a north-west facing slope.[1] The others being Workman's Wood in Gloucestershire[1][2][3] and Windsor Hill SSSI, a site in the Chilterns in Buckinghamshire.[1][4] The species was first found at Hawkley Warren in 1986 by K. Turner and Ralph Hollins.[5]
Other orchid species found growing under beech at this site include Bird's-nest Orchid, Early Purple Orchid and Narrow-leaved Helleborine; Spurge-laurel is also found.
Ramsons is found in the valley bottom and Herb Paris is also found here.
Invertebrates
[edit]The Mountain Bulin snail Ena montana occurs here.
