‘Enormously thrilling’: farm to create largest pure grassland in southern England

The rolling hills south of Salisbury Plain are a bleak scene of huge arable fields and tightly grazed pasture dotted with scores of sheep.

In latest many years, Decrease Pertwood farm has embraced natural rising, producing oats, barley and different crops, whereas boosting numbers of uncommon corn buntings and different wildlife with wildflower banks and newly planted timber.

However as wildlife continues to say no in Wiltshire and the farm’s income plummet amid an more and more unpredictable local weather, the homeowners are turning to farming nature as a substitute.

The two,800-acre arable farm begins its transformation this spring into the largest grassland rewilding mission in southern England, in an try to revive declining crops, bugs and endangered species together with cuckoos, grasshopper warblers and turtle doves.

The “Pertwood Plain” mission, masterminded by Restore, a land administration firm specialising in large-scale restoration led by the naturalist Benedict Macdonald, will in the end see low densities of pigs and cattle roaming free to recreate flower-rich chalk grassland. This naturalistic grazing, alongside interventions comparable to including inexperienced hay and brash piles the place birds perch and excrete seeds into the soil, will give rise to a mosaic of grass and scrubland teeming with invertebrate life.

Sooner or later, guests might benefit from the return of extinct species together with the nice bustard, which has been reintroduced on to close by Salisbury Plain, and the charismatic red-backed shrike, which turned successfully extinct as a breeding fowl in Britain within the Nineteen Nineties.

“It’s enormously thrilling,” mentioned Macdonald. “Salisbury Plain on the horizon is sort of a big, free seed financial institution of species, a few of which – such because the reintroduced nice bustard – would possibly naturally discover Pertwood because it begins to get well.”

Tamara Webster, the director of the family-owned farm, mentioned: “We now have been trying, nearly subconsciously, for a very long time for an all-embracing blueprint for the long run. One that may ship environmental restoration, really sustainable meals manufacturing and obtain monetary stability and profitability. That is why we commissioned the holistic analysis by Restore and we’re extraordinarily enthusiastic about what we hope to attain collectively.”

In 2022, this huge arable farm on grade 3 farmland (a measure of excellent to average rising soils) made £179,000 revenue. The next yr, it posted a £180,000 loss, spending £135,000 on fertiliser, £65,000 on muck and slurry, £43,000 on pink diesel and shedding £113,000 on farm equipment depreciation.

The rewilded farm will lower fertiliser and these different prices to just about zero and dump its costly equipment. Employees numbers are anticipated to stay the identical with some retained for brand spanking new roles comparable to grazier. Sometimes, rewilded estates make use of extra individuals than standard agriculture.

An rising variety of conventional farms are turning to nature regeneration as buyers financial institution on speculative future revenues from carbon and biodiversity credit and funds for biodiversity internet acquire (BNG). That is the place builders are legally obliged to “purchase” or create pure areas to make sure each new housing property results in an uplift in nature.

Pertwood is setting apart a modest 50 acres for BNG and can proceed to supply meals – natural beef and pork – however its transition has been made financially easy by a “wooden pasture” funding choice within the authorities’s countryside stewardship scheme. This ensures the farm annual funds of £300,0000 for 10 years.

The wooden pasture funding is proving fashionable with farmers who’ve been reluctant to fully cease farming and switch land over to forestry to sequester carbon. To create wooden pasture, farmers can proceed low-density livestock farming however permit scrub and woods to naturally regenerate and develop over fields to create a mosaic, which advantages a variety of species and sequesters carbon.

Matt Collis, the lead ecologist at Restore who’s measuring soil well being and biodiversity at Pertwood, mentioned: “Calcareous grassland is at all times probably the most numerous and botanically wealthy soil kind, with 50 or 60 plant species in just a few sq. metres. To get that into its ecological peak could be very thrilling. The chance for surprises could be very excessive right here. The soil needs to be ample, it needs to be wealthy with wildlife.”

However turning food-producing land over to nature is controversial for a lot of farmers and politicians who cite fears over meals safety or argue it is going to trigger extra meals imports and, in impact, Britain exporting its environmental harms.

Macdonald mentioned: “We’re not arguing that the entire of Wiltshire or Britain must be given this therapy. We’re advocating having countywide biospheres which can be massive sufficient to halt or reverse species decline which we’re seeing in Wiltshire – fewer cuckoos and whinchats and insectivorous birds yearly. That may solely actually be addressed with [nature at] scale.

“It’s a delusion that by creating nature we destroy meals manufacturing. The meals manufacturing system is doing a superb job of destroying itself by making itself unsustainable. The concept that taking 2,800 acres of underperforming arable right into a nature-based system goes to hazard the human meals chain or the standard of the meals we eat is solely not true.”

Based on Macdonald, the farm might develop fruits in new orchards, allow foraging for wild fruits and nuts and even truffles, in addition to producing free-range natural beef and pork. In the meantime, the wildlife that it produces – pollinators in addition to pure pest controllers – will assist different farmers within the area.

What’s going to Pertwood Plain seem like in 20 years’ time?

“We all know it’s going to be hotter, we all know it’s going to be drier,” mentioned Macdonald. “To come back right here and stroll by way of a climate-resilient system that is stuffed with life can be the apparent dream – a feathered, multilayered, self-sustaining panorama.

“It will be beautiful to see red-backed shrike perched within the blackthorns skewering beetles once more – these birds had been so frequent within the 1850s they had been breeding in again gardens and we now have eradicated them from the British panorama.”
