The Hinton Ampner: Reimagining a Hampshire Estate project is a long-term commitment to transforming this historic National Trust estate into a more vibrant, accessible and sustainable place where people and nature can thrive.

The main aims of the project are:

Nature recovery and conservation: creating diverse new habitats so wildlife can thrive
Regenerative farming: more environmentally friendly and sustainable practices
Better access to nature: larger, more varied green space with improved access
Involving people: volunteer opportunities, community projects and visitor engagement
Responding to climate change: increased carbon capture and resistance to extreme weather

The work so far

Back in 2021, we began converting 27 hectares of farmland into wood pasture and grassland. We also appointed our farming partner to help us care for our farmland and by introducing a herd of rare breed Sussex cattle. The outcomes are apparent in a greater variety of wildflowers and larger areas of grassland for our cattle.

In 2024, our focus fell upon woodland creation and tree planting. We have welcomed numerous community groups and families to join us in planting 0ver 50,000 new trees including oak, field maple, crab apple and holly.

The local community have been key to delivering woodland creation at such a massive scale, we welcomed 77 groups with 25% of all groups comprising young people, including schools, scouts, colleges & universities.

One of our woodland creation sites, Godwins Park, is adjacent to the local village and nursery. The new woodland will create a welcoming, blossom-rich space for people to come and enjoy.

If you wish to get involved in future tree planting days, please email us: hintoncountryside@nationaltrust.org.uk We intend to run future tree planting days from Autumn 2026.

Preserving Ralph Dutton’s vision

Ralph Stawell Dutton, the 8th Lord Sherborne, was an author, historian and collector, as well as a great supporter of the National Trust. He inherited Hinton Ampner in 1935 and left the entire estate to the Trust on his death in 1985.

Dutton was responsible for expanding the estate and using landscaping and planting to enhance the stunning views from the house over the South Downs National Park.

As the 'Reimagining' project continues, there will be a steady change to the landscape. But 300 new trees planted in the parkland will continue Dutton’s tradition of creating small copses to soften boundaries and give structure and symmetry to these magnificent views.

Hinton Ampner has a vision of creating something really quite special for people and wildlife in the South Downs National Park.

Main aims of the 'Reimagining' project

The project has five main aims, each complementing and supporting the others. Click through to find out more about some of these key areas.

Regenerative farming: By restricting the use of chemicals and following regenerative farming practices, we’ll improve soil quality and reduce the impact on the wider environment. Our farming partner will focus on sustainable, nature-friendly food production rather than commercial targets.Find out more
Better access to nature for everyone: We’ll use some of this land to expand the area of green space where visitors can roam, and create a richer and more varied landscape. A new circular trail with accessible and latch-free gates and improved & extended paths will make nature accessible to everyone.Find out more
Involving the community and visitors: We continue to engage with local communities and volunteers to help plant trees and look after our saplings.
Responding to climate change: Planting trees and regenerative farming practises will increase carbon capture and improve resilience against the impacts of climate change, including droughts and flood events.

Species Highlights

As we near the end of our tree planting season, our running total this winter is officially over 16,000! In addition to well-known trees and shrubs like oak, field maple, and blackthorn, we are also planting some commonly overlooked species. One of these is the Wayfaring tree, named by a herbalist in 1597 who noticed it often appeared near paths. The shrub has clusters of scented white blossom and berries that change from red to black. Another species is Wild Service, a rare tree with jagged leaves whose fruits are loved by birds and are also edible to us, said to taste like dates.

Frequently asked questions

We are keeping 110 hectares of farmland on the estate at Hinton Ampner to grow crops and will be using sustainable practices to improve the soil and make the land more productive in the coming years, decades and beyond.

We will also be rearing native-breed Sussex cattle at Hinton by grazing them on other land around the estate, such as grassland and wood pasture. As well as providing food for the cattle, this will help to create and maintain species-rich wildlife habitats.

Over two-thirds of the UK’s surface area is currently being used for agriculture, and according to the UK Government’s Food Security Report 2021 there is no current food security issue linked with lack of productive farmland.

Instead, the report states that the biggest medium- to long-term risks to the UK’s domestic food production come from climate change and other environmental pressures like soil degradation, reduced water quality and the decline in biodiversity. The steps we are taking at Hinton Ampner will address all of these issues.
At Hinton Ampner, we'll continue to farm livestock and grow arable crops, but less intensively and using sustainable farming practices.

Unproductive field corners have been left to enable trees to self-seed, whilst other fields are being manually planted with saplings. This will lead to significant increases in biodiversity, healthier soils and reduced carbon outputs.

We will also be planting trees and hedges to create new and extended areas of woodland and hedgerow, while focused grazing will help to manage grasslands, another important wildlife habitat.

This is just part of a long-term strategy to improve the estate for people and nature. It has been carefully planned and will be closely managed for years to come.
No. At Hinton Ampner, we'll continue to farm livestock and grow arable crops, but less intensively and using sustainable farming pra ctices. This will lead to significant increases in biodiversity, healthier soils and reduced carbon outputs.

Planting trees and hedgerows may eventually lead to parts of the estate looking ‘wilder’ than they have done for many years but some areas will still be managed with strategic grazing and fencing.

This is just part of a long-term strategy to improve the estate for people and nature. It has been carefully planned and will be closely managed for years to come.

The National Trust is the largest conservation charity in Europe with huge experience of managing the countryside for landscape, wildlife, and public enjoyment. We see room for many different levels of ‘wildness’ and domestication on our land and will always seek to apply these different treatments in a locally appropriate and considered way for the benefit of biodiversity and people.
Much of what are considered by ‘weeds’ by some farmers, are part of our native flora and have significant benefits for wildlife.

One expert study found that the abundance and diversity of pollinating insects visiting these native ‘weed’ species averaged twice that of the plant species recommended for pollinator-targeted agri-environmental schemes. Where these native species labelled ‘weeds’ grow as part of a naturally regenerating community of plants, they indirectly support farming by supporting pollinators.

Only one major 'weed', ragwort, is in any way toxic to livestock and only if eaten in great quantity, which is rare. Harmful situations can sometimes occur when it is included (in high quantities) in hay, or when animals have very little else to eat due to over-grazing. Ragwort germination and growth happen in competition-free gaps in the vegetation; the kind that are produced by cultivation or by heavy grazing from domestic stock like sheep or horses. But in well-managed dense grassland, the amount of ragwort is controlled naturally by competition and reduction of suitable germination sites.

For more information on ragwort and the common myths surrounding it see: https://www.ragwortfacts.com.
One of the key aims of the project at Hinton Ampner is to increase access to green spaces for visitors and the local community.

Around 75 more acres will become available to the public, with a total of 10 km of new paths through the estate. Visitors will be able to roam over a larger and more varied landscape, while a new trail with accessible gates and improved paths will make nature accessible to everyone.

In some cases, we may need to use fencing to separate walkers and dog owners from grazing livestock or breeding wildlife, such as ground-nesting birds, just as any livestock farmer or nature reserve warden would.
Sheep tend to graze very close to the ground, cropping the grass blades short and to the same length. They also prefer the flowering heads and buds of many plants. This can lead to a lack of variation in grass lengths and plant species, which would otherwise provide habitats for many valuable insects and other invertebrates that are the basis of the wildlife food chain.

Cattle are less selective grazers and are likely to graze an area of vegetation to a medium height. They also remove long, coarse grass and use their tongues to pull up tufts of vegetation. When cattle are grazed in responsible numbers, such as at Hinton, this leaves tussocky grasses with a variety of micro-habitats.
By increasing the range and size of habitats at Hinton, and restricting the chemicals that go into the land, we’ll give all kinds of plants and wildlife a greater chance of thriving here.

‘Unimproved’ grassland, and wild field borders on the estate farmland, will support a wider variety of plants and insects.

This in turn will provide food for an array of birds, reptiles and mammals, while extended and joined up woodland and hedgerows will support larger, more sustainable populations.

The overall mosaic of habitats on the estate will provide appropriate breeding, commuting and over-wintering habitats.

As the land becomes healthier, and the landscape more diverse, the growth in the range and number of plant, insect and animals species should start to gather pace.
