Grassland 3.4.1 Unimproved and Semi-improved Neutral Grassland
Most areas of semi-improved grassland crossed by the cable route comprise rough, rank grass species and ruderal herbs. Specific examples are grasslands located at Target Note 17, 201 and 304.
Target Note 17 describes a series of fields used for cattle grazing. Poa trivialis (Rough Meadow-grass) and Hordeum vulgare (Six-rowed Barley) are the most frequent grasses Associate species include the coarse grasses Alopecurus pratensis (Meadow Foxtail), Dactylis glomerata (Cock's-foot) and Elytrigia repens (Common Couch). Small patches of Deschampsia cespitosa (Tufted Hair-grass) occur throughout area. Herb species present include common species such as Cirsium arvense (Creeping Thistle), Geranium dissectum (Cut-leaved Crane's-bill) and Rumex obtusifolius (Broad-leaved Dock). The grasslands are referable to the NVC type MG9a Holcus lanatus – Deschampsia cespitosa grassland, Poa trivialis sub-community. An NVC table for target note 17 is included in Table 7.4.
Target note 201 describes a series of abandoned arable fields to the south of Woodbridge. They are species-poor being dominated by Elytrigia repens (Common Couch) and Holcus lanatus (Yorkshire-fog). Old tracks between the fields provide areas for uncommon species associated with disturbed areas to grow including Crassula tillaea (Mossy Stonecrop) and Filago vulgaris (Common Cudweed). This field system cannot be ascribed to any one NVC community.
Target Note 304 describes a field on a slope with zonation in the vegetation according to the slope. The lower slopes and much of the field is dominated by a very species- poor Holcus lanatus (Yorkshire-fog) dominated sward. At the top of the slope (the southern edge of the field) the sward becomes more species-rich. These comprise species typically associated with soil disturbance such as Arenaria serpyllifolia (Thyme- leaved Sandwort), Chamerion angustifolium (Rosebay Willowherb) and Vulpia bromoides (Squirreltail Fescue) as well as calcifuges such as Ornithopus perpusillus
