Site Description

This site is located about 1.5km to the south of Addingham, and about 3km to the west of Ilkley. It is surrounded by agricultural grassland, some of which is cow grazed. There is also a golf course and caravan site to the south-west of the site, and a scrubby/ wooded area to the west.


The majority of the site contains species rich grassland, which is a little hummocky, and damp in parts. It did not have stock on it when the site visit was carried out, but cow hoof marks could be seen across the field. The grassland community is MG5, and is host to species such as: frequent Holcus lanatus, Centaurea nigra and Stachys sylvestris, occasional Agrostis capillaris, Dactylis glomerata, Deschampsia cespitosa, Rumex acetosa, Ranunculus repens, Plantago lanceolata, Dactylohriza fuchsii, Lotus pedunculatus, Trifolium repens, T. pratense, Cirsium arvense, Succisa pratensis, Potentilla erecta and Achillea millefolium, and locally abundant Juncus acutiflorus.


There is a beck flowing through the northern part of the site, from west to east. This is surrounded by the W7 woodland, with species including: occasional Alnus glutinosa, Acer pseudoplatanus and Fraxinus excelsior in the canopy, occasional Corylus avellana, Crataegus monogyna, Ilex aquifolium and Ulmus glabra in the shrub layer, and occasional Chrysosplenium oppositifolium, Valeriana officinalis, Dryopteris dilatata, Digitalis purpurea, Viola riviniana, Geranium robertianum, Oxalis acetosella, Rubus fruticosus, Urtica dioica and Ranunculus repens, locally frequent Glyceria fluitans, Holcus mollis, Mercurialis perennis and Hedera helix, and rare Sanicula europaea, Viola sylvatica, Cirsium palustre, Cardamine amara, C. flexuosa, Carex remota and C. sylvatica in the ground flora.


There are a few small scrubby sections throughout the site. Species present here are: locally frequent Ulex europaeus and Ulmus glabra, occasional Crataegus monogyna and rare Rosa canina.


There is a line of scrub, with spaces in between, which may be an old hedgerow. It contains: locally frequent Rubus fruticosus and rare Crataegus monogyna, Alnus glutinosa, Ulmus glabra and Ilex aquifolium.
