What is Upland Hay Meadow?
Upland hay meadows are species rich grasslands dominated by a mix of fine grasses and abundant herbaceous wildflowers such as sweet vernal-grass, wood crane’s-bill, great burnet, pignut, and lady’s mantles.
These meadows have developed through long term traditional management that combines light grazing with a late summer hay cut. Rare species including lesser butterfly-orchid and burnt orchid are sometimes found.
This habitat is a dense mix of grasses and a wide variety of wildflowers, with no single grass species dominating the vegetation.
Why It Matters for BNG
Upland hay meadows deliver very high distinctiveness units and contribute significantly to BNG targets. They showcase visible, species rich outcomes valued in planning.
Traditional hay cutting and aftermath grazing create high value BNG supply. Meadows align with low input upland farming and long-term stewardship.
Where You'll Find It
Upland hay meadows are confined mainly to upland valleys in northern England and parts of Scotland. Key areas include the North Pennines, Lake District and County Durham, with smaller areas in Perthshire and Aberdeenshire.
These meadows typically occur on brown earth soils at altitudes between 200m and 400m and are managed traditionally for hay production or as grazed fields in upland landscapes.
Soil & Site Requirements
Upland hay meadows favour well drained brown earth soils with a pH above 5.5. Nutrient levels must remain low, particularly phosphorus. Sites are usually level or gently sloping and subject to traditional hay meadow regimes. The soil is usually neutral, reasonably fertile, and well-drained, supporting lush vegetation suitable for hay production.
How New Upland Hay Meadow Is Created
Inputs
• Prepare the seedbed carefully before sowing
• Use locally sourced seed or green hay from species rich donor meadows
• Avoid fertiliser and control perennial weeds before seeding
• Encourage natural colonisation where local sources are available
Management
• Cut for hay in late July to early August
• Apply aftermath grazing following the hay cut
• Maintain low intensity management to support establishment
Landscape
• Restore meadows close to existing species rich grassland to maintain local character
• Use green hay from nearby upland meadows to retain local genetic diversity
• Position creation where long term management and monitoring can be secured
How Existing Upland Hay Meadow Is Improved
Inputs
• Control invasive or undesirable species
• Spread green hay to increase species diversity
• Apply small amounts of farmyard manure only where appropriate to maintain structure
Management
• Maintain traditional cutting and aftermath grazing
• Adjust timing to match flowering and seed set in different years
• Avoid overgrazing or complete neglect, both of which reduce species richness
• Protect indicator species such as wood crane’s bill and lady’s mantles
Landscape
• Restore adjacent land to enlarge existing meadows
• Reinstate traditional hay meadow systems to strengthen landscape character
• Improve connectivity across upland valleys by linking species rich fields
Target Condition
Upland hay meadows in their defined BNG condition should:
• Support high plant diversity with a wide range of grasses and herbaceous species
• Maintain low nutrient status with no dominance of coarse grasses or weeds
• Demonstrate continuity of traditional cutting and grazing regimes
• Contain indicator species such as wood crane’s bill and lady’s mantle
• Present a balanced sward structure typical of MG3 grassland
The BNG Value of Upland Hay Meadow
• Distinctiveness: Very high
• Condition Potential: Can be maintained or enhanced through traditional hay cutting and aftermath grazing
• Restoration Pathway: Recognised outcome where traditional upland meadow management is restored or secured
• Strategic Value: Strengthens upland ecological networks and supports specialist plants, insects and birds

Frequently Asked Questions
What is Upland Hay Meadow?
Species-rich hay meadows found in upland areas (often dales), typically on neutral or slightly acidic soils. They are managed by taking a hay crop. It is a very rare priority habitat.
How is BNG measured here?
Condition is assessed based on the presence and abundance of a specific list of positive indicator species (e.g., Globe-flower, Wood Crane's-bill) and the management history.
How can I achieve BNG?
Enhancement requires restoring the traditional management regime: cessation of fertilizer and annual hay cutting after the flower/seed set (usually late July/August).
What is the BNG target condition?
A Very Good condition is the goal, requiring a high diversity and abundance of characteristic upland meadow wildflowers.
What management is required?
Annual late hay cut and removal, followed by aftermath grazing (or no grazing) over winter. Removal of the cuttings is vital for BNG success.
Exploring Other Habitats?
Arable Field Margins Pollen and Nectar
Arable field margins pollen and nectar are grass margins around arable fields sown with wildflowers and legumes managed specifically to provide pollen and nectar resources for invertebrates. The mix must include at least four nectar-rich flowering species and the margin is kept low-input and rotationally cut to maintain flowering through the season. The arable field must remain in a crop rotation including an arable crop.
Unlike wild bird seed margins, the management objective here is flowering continuity for pollinators rather than seed retention for birds. This habitat type sits within the Cropland broad habitat in the BNG metric and is classified separately from tussocky margins, cultivated margins and game bird mix.
Arable Field Margins Game Bird Mix
Arable field margins game bird mix are margins, strips, blocks or corners around arable fields sown with wild bird cover crops and left unharvested over winter so that seed produced by the plants remains available to farmland wildlife. The arable field must be in a crop rotation that includes an arable crop, such as wheat, barley, maize or oats, even if in certain years the field is in temporary grass, set-aside or fallow.
Mixes typically combine seed-bearing cereals, brassicas and oil-rich crops to provide food through the winter hungry gap and standing cover for gamebirds and declining farmland bird species.
Arable Field Margins Cultivated Annually
Arable field margins cultivated annually are strips along the edges of arable fields, typically 2–12 metres wide, managed under a low-input regime to support annual arable plants. They are lightly cultivated each year, usually in late summer or autumn, without herbicide or fertiliser, creating the open, disturbed soil conditions that annual arable flora requires to germinate.
