Key Points

• Reintroduction of Livestock: A flock of rare-breed sheep has been reintroduced to Anthill Meadow on the Hampstead Heath Extension to undergo a two-week conservation grazing trial.
• Project Partnership: The ecological trial is operated jointly by the City of London Corporation, the Heath & Hampstead Society, the Rare Breeds Survival Trust, Mudchute City Farm, and volunteer organization Heath Hands.
• Restoring Historical Practices: The scheme revives traditional land management practices that occurred on the Heath for centuries before stopping in the 1950s.
• Biodiversity Benefits: Selective nibbling by the sheep controls dominant flora species, protects yellow meadow ant mounds, and provides micro-habitats for birds such as the green woodpecker.
• Potential Expansion: Success during the trial could lead to the rollout of similar natural grazing initiatives across other green spaces and parks in London.
• Community Engagement: Over 60 local volunteers are managing two-hour shepherding shifts to monitor livestock welfare and inform members of the public about urban conservation efforts. The Heath & Hampstead Society

Hampstead (North London News) September 12, 2026 – Five rare-breed sheep have returned to the Hampstead Heath Extension as part of an ecological conservation initiative designed to control plant overgrowth, boost local biodiversity, and explore expanded natural land management options across London’s urban green spaces.

Why Have Sheep Been Introduced to Hampstead Heath?

As reported by Francis Read of MyLondon, five rare-breed Norfolk Horn and Oxford Down ewes on loan from Mudchute City Farm in east London were moved onto Anthill Meadow on Wednesday, September 9, 2026. The flock will remain on site grazing between 8:00 AM and 7:00 PM daily through Monday, September 21, before being housed safely in local stables each evening.

The primary purpose of the trial is conservation grazing—an established environmental management technique where livestock selectively trim aggressive grasses and scrub. According to reporting by the Ham & High, the target area on the Hampstead Heath Extension is home to fragile anthills created by yellow meadow ants. The uneven terrain makes mechanical mowing equipment unsuitable, as conventional machinery risks crushing the anthills and destroying critical insect micro-habitats.

The anthills provide a vital foraging resource for species higher up the ecological chain, including green woodpeckers. Natural grazing allows for a mosaic of vegetation heights, prevents aggressive weeds from smothering rare wildflowers, and avoids soil compaction caused by heavy tractors.

What Did Key Officials and Stakeholders Say About the Scheme?

As reported by Ham & High, Alderman Gregory Jones KC, Chair of the City Corporation’s Hampstead Heath, Highgate Wood and Queen’s Park Committee, highlighted both the ecological and historic importance of the project, stating:

“Grazing sheep were a familiar part of Heath life for generations, and archive discoveries have helped us better understand that history. We’ve also learned through recent trials these traditional methods can still deliver real benefits for nature today, particularly in sensitive habitats where grazing offers a low-impact alternative to machinery. By bringing sheep back to the Heath, we’re reconnecting with that heritage while learning how to care for this special landscape in the future.”

Former Committee Chair William Upton KC previously noted during initial trials covered by the City of London News Desk that

“Reintroduction of grazing like this has been an aspiration for many years, as it could play a key role in creating new rich and diverse habitats for the Heath’s wildlife. It also harks back to the Heath’s past, when farmers would bring their flocks to the site before taking them to market in the City.”

Highlighting the specific botanical benefits, John Beyer, Vice-Chair of the Heath & Hampstead Society, detailed the ecological target:

“The sheep have the task of nibbling away at Creeping Cinquefoil and other plants smothering the anthills on that part of the Heath. We are all looking for ways to manage the Heath in a more ecological manner.”

To formally launch the 2026 grazing session, a ceremonial declaration was held in the presence of representatives from the City of London, Tom Davis from Mudchute Farm, and Masters of both the Worshipful Company of Woolmen and the Worshipful Company of Butchers.

How Is the Impact on Biodiversity Being Measured?

As noted by the Ham & High, the London Natural History Society is actively monitoring the environmental effects of the flock. Ecological surveys were conducted across the meadow before the ewes arrived and will be repeated immediately following the end of the two-week grazing period to measure shifts in plant species diversity and structural changes to the habitat.

Additionally, charity organization Heath Hands has mobilized more than 60 community volunteers to act as temporary shepherds. These shepherds work two-hour shifts to monitor the physical condition of the rare-breed ewes, inform curious members of the public about the environmental goals of the project, and remind dog owners to keep pets on leads around the enclosure.

Background of Conservation Grazing on Hampstead Heath

Hampstead Heath, spanning 790 acres in North London, is registered as a Site of Metropolitan Importance for Nature Conservation and receives over nine million visits each year.

Archival research confirmed by The London Archives indicates that agricultural grazing was standard practice on Parliament Hill and the broader Heath terrain dating back to at least the 18th century. Local farmers routinely drove livestock across these pastures to maintain vegetation until the practice was phased out during the mid-1950s.

Without grazing animals or intensive manual labor, open grassland landscapes gradually transition into dense scrubland and secondary woodland. While secondary woodland benefits certain bird and small mammal species, it significantly reduces open meadow flora, butterflies, and burrowing insects.

Following a limited 2019 pilot scheme, the City of London Corporation reintroduced periodic conservation grazing trials in September 2023. These periodic sessions evaluate whether heritage livestock breeds—such as Norfolk Horn and Oxford Down, which are adapted to forage tough vegetation—can reliably manage sensitive micro-environments without disrupting public recreation.

Predictions: How This Development May Affect Urban Visitors, Environmentalists, and Regional Councils

The outcome of the Hampstead Heath grazing initiative is poised to directly influence several primary groups across London and regional urban centers:

• Local Residents and Park Visitors: If natural grazing becomes a permanent fixture of Hampstead Heath’s management plan, park visitors can expect increased seasonal closures of small meadow zones and stricter requirements for dog control. However, visitors will also gain unique educational access to rare livestock breeds and richer wildlife viewing opportunities as insect and bird populations recover. Heath Hands
• Conservationists and Ecologists: Positive data from the London Natural History Society’s surveys could offer a proven blueprint for non-mechanical habitat restoration. A successful trial demonstrates that low-carbon, animal-led land management is a scalable alternative to fossil-fuel-powered lawnmowers and chemical weed suppression in metropolitan areas.

• Local Councils and Park Authorities: Municipal bodies across Greater London monitoring the Hampstead Heath trial may adopt similar livestock grazing strategies in difficult-to-mow municipal parks, riverbanks, and nature reserves. Substituting heavy machinery with seasonal livestock loans from urban farms offers local councils a cost-effective, sustainable approach to achieving biodiversity net-gain targets.
