| HABITATS: Grassland |
The Trust manages a number of different grassland habitats, supporting distinctive plant communities, and each requiring specific husbandry. The main examples are detailed below
| Grassland: unimproved calcareous pasture |
‘Lowland calcareous pasture’ is a priority habitat under the UK Biodiversity Action Plan (BAP) and is found on shallow lime-rich soils generally overlying limestone rocks. Because it is ‘unimproved’ (never treated with inorganic fertiliser) it supports a very rich flora and invertebrate fauna, including many nationally rare and scarce species. It also provides feeding or breeding habitat for a number of scarce or declining birds including skylark, a BAP priority species. During the last 50 years 97% of Britain’s unimproved grassland has been destroyed by farming.

Roundhill SSSI Roundhill is a complex of three south-facing fields on the upper slopes of Bredon Hill extending over 20 acres (8.1 ha). The centre field is particularly species-rich and has been designated a Site of Special Scientific Interest (SSSI) for its limestone flora. It supports an abundance of attractive flowers, including pyramidal orchid, fairy flax, quaking grass, rock-rose and mouse-ear hawkweed. The grassland attracts a large number and variety of butterflies, including meadow brown, marbled white, ringlet, gatekeeper, common blue and brown argus. All three fields are managed as ‘pasture’ and are grazed at a low density by cattle during the late spring and summer. No fertilizers or pesticides are used, and roguing – the control of weeds by hand – is sometimes necessary. During the Trust’s eighteen year management there has been a noticeable improvement of the flora in the two outer fields – one of its key aims. |

Quarry Field
Quarry Field is 4.4 acres (1.8 ha) of south-facing calcareous pasture managed under Countryside Stewardship. This involves grazing at a low stocking density, no use of fertilizers and only very limited herbicide use. This will produce a gradual improvement in the structure and botanical diversity of the sward.
| Grassland: unimproved neutral pasture |
‘Unimproved neutral pasture’ is a subdivision of the BAP priority habitat ‘lowland meadows’. It is an increasingly rare habitat, occurring on free-draining soils, and characterised by a low proportion of rye grasses coupled with a wide range of other grass species.
Squitterbrook
The Trust manages an example of this type of grassland at Squitterbrook, Kemerton, owned by the Overbury Estate. The sward and field margins contain a rich variety of plants, including crested dog’s tail, sheep’s fescue, green-flowered helleborine, bee orchid, lady’s bedstraw, red clover, cowslip, and meadowsweet. The pasture is home to many bird and animal species, including polecat and the BAP priority species barn owl. It is managed traditionally, by summer grazing and occasional cutting. Control of docks, ragwort and creeping thistle is sometimes carried out by a combination of topping, spot-spraying, and roguing.
| Grassland: flood meadows |
‘Unimproved seasonally-flooded grassland’ is a subdivision of the BAP priority habitat ‘lowland meadows’. These include well-known but now very rare Lammas meadows, which are shut up for hay in early spring, cropped in July, and grazed after Lammas Day on 1st August. Nutrients are supplied by flooding episodes in winter. Less than 3,700 acres (1,500 ha) of flood meadow now exist in the United Kingdom.

Twyning Ham and Brookfield Meadows The Trust manages two blocks of Lammas meadow on the banks of the Avon – parts of Twyning Ham and Brookfield Meadows. Together they total around 37 acres (15 ha) of grassland which floods regularly during the year. This constitutes 1% of all the flood meadow surviving in the UK The meadows are dominated by the plant community, defined as MG4 in the National Vegetation Classification, and characterized by the presence of greater burnet. They are managed traditionally, being cut for hay in July, and grazed communally after Lammas Day. Work has been carried out at Brookfield Meadows to improve the habitat by blocking land drains and raising the water table. The flood meadows support important breeding populations of wading birds such as redshank, oystercatcher and curlew, as well as the BAP priority species, corn bunting. They are home to rare plants including fine-leaved water dropwort and mouse-tail. |

| Grassland: hay meadows |
|
‘Hay meadows’ are a subdivision of the BAP priority habitat ‘lowland meadows’, and are characterized by a diverse and colourful flora. In early summer they are carpeted with bulbous buttercup, meadow buttercup and creeping buttercup, interspersed with typical meadow plants including quaking grass, hairy sedge, lady’s bedstraw, yellow rattle, and adder’s-tongue fern. Lowland meadows are an important habitat for skylark, a BAP priority species, and a number of other farmland birds. Long Meadow Long Meadow in Kinsham is a species-rich old hay meadow. In 1987 traditional management was re-introduced to the meadow after a period of decline. The hay is cut in July – later than usual in modern farming – allowing flowers to set seed. The aftermath is grazed by sheep. This regime has brought about a significant improvement in plant biodiversity, thanks in part to the spread of yellow rattle, a plant which parasitizes and suppresses more dominant grass species. The Sling It is hoped that similar progress will be achieved at another species-rich hay meadow in Kinsham, The Sling, which has come under Trust management more recently. This meadow is located between the Carrant Brook and Squitter Brook, and contains greater burnet in some of its wet-lying areas. |

| Grassland: agriculturally improved |
The Trust oversees around 60 acres (24 ha) of ‘improved’ pasture; grassland which has in the past been treated with fertilizer to produce better growth. It may be grazed throughout the summer months, or else cut for silage or hay, to be fed to animals during winter. As with arable land, particular care is taken with the use of herbicides and fertilizers around the margins of fields.
| Grassland: Livestock |
|
Grazing at the correct time with the right number of animals is an
essential element in the management of all the various types of
grassland. Much of the Trust’s grassland is grazed by a Red Poll
single-suckler beef herd, under an independently audited assurance
scheme for livestock – the Assured British Meat (ABM) Beef and Lamb
Quality Assurance Scheme.
The cows and their calves spend the summer months out at grass. They are bulled during July and August. Each November when the grass has stopped growing they are brought in to over-winter inside. At this time the calves are weaned and the cows dried off. All male calves are kept entire and are put onto a diet of rolled barley and beans. These are sold direct to an abattoir when they reach a weight of 600 kg at about 12 months of age. Heifer calves are sold the following spring as ‘stores’, or are kept as herd replacements. The cows calve in the spring and once they have mothered up, they are put out to pasture and the cycle begins again. |

Some Trust grassland is grazed by a herd of North Country Mule sheep. These arrive each October from the Cumbrian highlands as immature ewes. They are too small to have been tupped that year and they spend the winter months grazing on lowland grass. Winter grazing by sheep forms part of traditional pasture and meadow management, and helps to promote a rich and diverse flora.
