Heathland Connections: Managing Land for Grayling Butterflies

Managing land for Grayling butterflies

Connecting Surrey’s Heathland

Lowland heathland in Surrey provides a key habitat for important bird, reptile and invertebrate species such as Nightingales, Adders and Grayling butterflies.

Our three-year Heathland Connections project will enhance, restore and connect habitats in the west of the Surrey Hills National Landscape, creating a better experience for people whilst protecting sensitive areas for wildlife.

Key habitats

Improving and better connecting these habitats in the wider landscape can increase the population and resilience of these rare species when faced with habitat loss, climate change and other pressures.

The project area and surrounding buffer zone include nine of Surrey’s Biodiversity Opportunity Areas, designated because improving habitat here is likely to have most impact on the connectivity and recovery of important species, including those which are the focus of this project.

Habitat Species

Why Graylings?

• The Grayling is one of eight butterfly species in Britain at the highest risk of extinction.

• Adults are brown and grey in colour with wings measuring 5 to 6 cm across. They are found from mid-July to midSeptember but their colouring camouflages them, making males difficult to see.

• The Grayling has suffered severe long-term decline in Britain (England) with numbers down by 72% (60%) and distribution by 92% (89%) since 1976.

• This is due to loss and degradation of habitat, scrubbing over of heathland and increased nitrogen levels in soils reducing the amount and quality of key food plants.

• The Heathland Connections project area includes three Biodiversity Opportunity Areas between Farnham and Haslemere where the Grayling butterfly has been identified. One area has a strong population, another a small but stable one and in the final area monitoring during 2022 suggested that the species is now extinct.

• Overall in Surrey the long-term decline has been halted, with numbers increasing since 1990 and up 61% in the five years from 2018 to 2023. Found primarily in the west of the county, the distribution of Graylings has also extended significantly (500%) over the same period with a small decline (16%) from 2018 to 2023. We want to sustain and continue this overall improvement.

Requirements

• Bare ground, tree trunks and rocks for males to bask on while looking for a mate.

• Suitable vegetation for females to hide amongst and lay their eggs. This includes grasses such as Sheep’s-fescue, Red Fescue, Bristle Bent and Early Hairgrass growing in sunny places with adjacent bare ground.

• Abundance of these key grasses throughout the year to provide food for caterpillars when they emerge and a place to hibernate over winter.

• Plentiful supply of nectar for adults to feed on from Bird’sfoot Trefoil, Bramble, Heather, Marjoram, Red Clover, Teasel and Thistles.

Life cycle

• Butterfly banks and scrapes can be seeded or planted with fine grasses - only successful in low-nutrient areas, which prevents rapid re-growth of original vegetation. Rotational topsoil stripping will help reduce nutrient levels.

• Managing woodland, for example by coppicing and creating disturbance along sunny rides/glades (by scarification or general machinery disturbance).

• Low to moderate stock grazing, with cattle or ponies, to create patches of bare ground and short vegetation. Where possible avoid:

• The use of pesticides.

How you can help

• By creating areas of bare ground and scattered vegetation that includes plenty of fine-leafed grasses. The butterfly only moves over short distances, so it requires suitable habitats in proximity for all stages of its lifecycle.

• Creating and maintaining these conditions which are found naturally in Surrey on lowland heathland and sometimes within grassland on chalky soils or in open woodland on stony ground. They can also be found in areas such as old quarries, railway lines and derelict industrial sites.

Habitat maintenance is necessary to retain the characteristics needed by Graylings. This can include:

• Scrub control to maintain a sparse covering to provide shelter through rotational cutting and treating stumps with herbicides if reduction of cover is required. Raking off the litter layer after cutting to expose more bare ground.

• Rotational cutting of small areas of heathland at 5-30 year intervals to create a variety of habitats which includes bare ground and sparse vegetation.

Habitats can also be created in a variety of ways:

• Rotational ground disturbance by scarification or turfstripping areas of grassland or scrub.

• Rotational management on brownfield sites, only parts managed each year to maintain a habitat mosaic.

• Applying topsoil, fertiliser or organic matter.

Grayling butterflies thrive in habitats with a mix of grassy areas and low shrubs. You can encourage or create scrubby or heathland areas with grasses and low-growing plants. This can be achieved by taking unproductive corners out of production, which are perfect for the larvae of Grayling butterflies to feed on.

Grayling butterflies rely on specific grasses, such as fescues and bents, for their larvae to feed on. You can plant and protect native grasses and wildflowers to support the butterfly’s life cycle, providing both food and habitat. Beetle banks, flower rich margins, and other options are a great way to achieve this.

Heathland restoration creates the open, sunny areas that Grayling butterflies need for basking and laying eggs. It also supports the growth of specific grasses, such as fescues, which are crucial for the larvae to feed on. Additionally, restored heathland provides a diverse range of habitats, enhancing the overall ecosystem and supporting the Grayling butterfly’s life cycle.

Graylings prefer open, bare ground for basking and egg-laying. You can leave patches of bare, unplanted soil in sunny areas to provide suitable habitat.

Light grazing can help maintain the open, sparse vegetation that Grayling butterflies prefer, but overgrazing can destroy their habitat. You can manage grazing to maintain the right balance of grasses and bare ground, which supports the butterfly’s habitat.

The Grayling butterfly is highly reliant on sunny spots for basking and warming up. You can create sunny, open spaces by managing vegetation to allow more sunlight to reach the ground, providing essential basking areas.

One of twelve landscape-scale Nature Recovery Projects being delivered collaboratively across England, Heathland Connections is a Natural England funded, partnership-led initiative, which will deliver habitat restoration by supporting landowners to effectively manage adjoining areas of remnant heathland under their care.

This project offers private and public sector landowners and managers of all sizes - from large to small scale farmers, woodland and forestry managers, and businesses such as golf clubs - a range of support to help them work together for nature.
