The Peppering Biodiversity Project

Boosting biodiversity with game cover crops in the South Downs

The Peppering Biodiversity Project is a success story for nature recovery being delivered at a large scale on an arable farm in West Sussex.

The near extinction of the grey partridge population in 2003 was a pivotal moment when the farm owner, the Duke of Norfolk, decided to do everything possible to reverse their fortunes, whilst ensuring a viable farming operation.

A pragmatic approach was needed with 85% of the farming operation focused on food production and 15% dedicated to linked habitats of hedgerow, grass and wild bird cover necessary to support the breeding success of grey partridge and other farmland birds.

The habitat creation figures are impressive. Since 2003, some 30 miles of new hedgerows have been created alongside various types of cover crops under the Countryside Stewardship and Sustainable Farming Initiative agri-environment schemes.

This includes 40 ha of 6m flower margins, 92 ha of 6m winter cover strips and 90 ha of 12m conservation headlands.

The flower margins are made up of native chalk Downland flowers and are full of the insect life so important to wild grey partridge chicks.

The winter cover strips shelter the hedgerow, provide additional nesting habitat for ground nesting birds, over winter cover from raptors and, of course, foraging opportunities.

The conservation headlands are where the farm operation does not use herbicides or pesticides, which means that part of the crop has arable weeds rich in invertebrate life, essential for farmland bird chicks to have sufficient food to grow and thrive.

To walk over Peppering is to witness a vast network of inter-connected ‘nature highways’ spanning the entire farm.

The other essential ingredient is predator management with a focus on fox, rat, stoat, weasel, crow and magpie. 

There is no doubt this a is top-draw project overseen by the Duke of Norfolk and with the support of Defra, Natural England and the South Down National Park. It builds upon the long-term commitment of the late Dr Dick Potts from the Game and Wildlife Conservation Trust.

In numbers, the results are staggering and inspirational. Grey partridge increased from a low of 11 birds to 2,000 by 2014 and have remained stable since. 

Lapwing, skylark, corn bunting, yellow hammer and wintering linnets are all up as well. Moreover, because of that network of linked hedgerow nesting cover and conservation headlands, small mammals are up which has resulted in increases in barn owl and numerous birds of prey making it their home.

We should not forget the invertebrates and plants. The site has over a thousand invertebrate species, over 10% nationally rare. There are over 100 broad leaf weeds and arable flowers found in the field systems managed with nature recovery firmly in mind.

The scale of the operation may perhaps feel out of reach for those of us with more humble means, but what it does do beautifully is evidence how these measures deliver for nature and can serve as an incredible inspiration for people to trust the science and take action at whatever scale they can operate at.
